本发明涉及家庭污水处理与回收领域，尤其涉及一种家用水处理控制方法及其装置。The invention relates to the field of domestic sewage treatment and recovery, in particular to a domestic water treatment control method and device thereof.
背景技术Background technique
目前，我国城市居民家庭日常生活中，洗衣、洗菜、洗浴等生活用水均采用自来水，使用一次就倒掉了，而洗衣以及厕所冲洗坐便器使用了大量的清水，消耗大量水资源，又排放大量污水，造成水资源的浪费。实际上除坐便器排放的污水以外，洗衣、洗菜、洗浴等生活废水均有回收利用的价值；回收的污水经处理后可以作为冲洗坐便器用水、洗衣以及清洗地面用水等等。因此，如何对家庭污水进行处理，并使之达到相应的标准的研究备受关注。At present, in the daily life of urban residents in our country, tap water is used for laundry, vegetable washing, bathing and other domestic water, which is poured out after one use, while laundry and toilet flushing toilets use a lot of clean water, consume a lot of water resources, and discharge A large amount of sewage causes waste of water resources. In fact, in addition to the sewage discharged from the toilet, domestic wastewater such as laundry, vegetable washing, and bathing have the value of recycling; the recycled sewage can be used as water for flushing toilets, laundry, and cleaning the ground after treatment. Therefore, the research on how to treat domestic sewage and make it meet the corresponding standards has attracted much attention.
家庭生活用水除冲洗坐便以外主要集中在洗衣、洗碗、洗菜以及洗漱上，现有技术中对洗衣用水的处理再利用大多是通过节水洗衣机或者絮凝洗衣机中水处理装置进行的，处理后的水仅用作洗衣机的漂洗用水，洗碗、洗菜以及洗漱用水往往是集中存放再进行过滤后用作冲洗马桶用水，可见现有的家用水处理是针对不同的污水单独设置处理装置，对于家庭生活中的不同类型的污水，还不能实现无差异化重复利用，使得家用水处理成本高、水处理装置的使用与检修都需要逐个进行，给用户造成了不便，并且处理后的水不能按照用户的需要随意取用。Household domestic water is mainly concentrated in laundry, dishwashing, vegetable washing and washing except for flushing toilets. In the prior art, the treatment and reuse of laundry water is mostly carried out through water-saving washing machines or water treatment devices in flocculation washing machines. The finished water is only used as rinsing water for washing machines. The water for washing dishes, vegetables and washing is often stored in a centralized manner and then filtered before being used as water for flushing toilets. It can be seen that the existing household water treatment is to set up separate treatment devices for different sewage. For different types of sewage in family life, it is not possible to achieve undifferentiated reuse, which makes the cost of household water treatment high, and the use and maintenance of water treatment devices need to be carried out one by one, causing inconvenience to users, and the treated water cannot be used. It can be used at will according to the needs of users.
为解决上述问题，技术人员着手研究针对家庭生活中的不同类型的污水统一进行处理再利用的装置，申请号为CN201020588377.0的中国专利公开了一种生活用水处理装置，用于小水量生活用水处理，主要由除砂器、臭氧反应装置、臭氧发生器、加压泵、絮凝加药箱、多介质过滤器、活性炭吸附器、中间水罐、精密过滤器、反渗透装置、储水罐和变频供水泵组成，处理工艺流程中包括混合、絮凝、沉淀或澄清、过滤及消毒，使得处理后的出水达到并高于生活饮用水水质标准。但是，用户对于经过处理后的家用水通常不会将其用作饮用水，而是满足一些要求不高的用途即可如擦地和冲洗坐便等。所以上述的生活用水处理装置就存在结构复杂、占地面积大、造价高、维修不便等问题。并且如果将家庭生活中的污水汇总到一起统一进行处理，由于污水的类型不同，无法像处理某一种污水时如处理洗衣水时可以根据洗涤水进水量或者洗涤衣物的重量或者材质来确定絮凝剂的投放量与絮凝处理次数，但是上述的生活用水处理装置无法确定絮凝剂的投放量与絮凝处理次数，所以难以达到预期的处理效果，并且如果为达到水处理效果，增加絮凝剂的投放量与絮凝处理次数，将会造成很大浪费。In order to solve the above-mentioned problems, technicians set out to study a device for unified treatment and reuse of different types of sewage in family life. The Chinese patent application number CN201020588377.0 discloses a domestic water treatment device for small-volume domestic water Treatment, mainly consists of desander, ozone reaction device, ozone generator, booster pump, flocculation dosing box, multimedia filter, activated carbon adsorber, intermediate water tank, precision filter, reverse osmosis device, water storage tank and Composed of variable frequency water supply pumps, the treatment process includes mixing, flocculation, sedimentation or clarification, filtration and disinfection, so that the treated water reaches and exceeds the quality standard of drinking water. However, users usually do not use the treated domestic water as drinking water, but to meet some less demanding purposes such as wiping the floor and flushing the toilet. Therefore, the above-mentioned domestic water treatment device has problems such as complex structure, large footprint, high cost, and inconvenient maintenance. And if the sewage in family life is collected together for unified treatment, due to the different types of sewage, it is impossible to treat a certain kind of sewage, such as washing water. The flocculation can be determined according to the amount of washing water inflow or the weight or material of the laundry. The amount of flocculant and the number of flocculation treatments, but the above-mentioned domestic water treatment device cannot determine the amount of flocculant and the number of flocculation treatments, so it is difficult to achieve the expected treatment effect, and if the water treatment effect is achieved, increase the amount of flocculant And the times of flocculation treatment will cause a lot of waste.
有鉴于此特提出本发明。In view of this, the present invention is proposed.

具体实施方式detailed description
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention , but not to limit the scope of the present invention.
现有技术中往往是针对某一种类型的污水，根据该类污水的脏污来源并且参考待处理的污水量等因素，确定絮凝剂的投放量，进行一次或者固定次数的絮凝处理。但是当需要对混合污水进行处理时，由于污水的类型不同，采用上述方法无法通过污水的脏污来源和污水量等因素确定絮凝剂的投放量，对其进行絮凝处理时，可能会出现絮凝剂的投放过量的情况，不但对水质造成影响，而且也导致絮凝剂浪费、水处理成本大的问题。In the prior art, for a certain type of sewage, the amount of flocculant is determined according to the pollution source of this type of sewage and with reference to factors such as the amount of sewage to be treated, and the flocculation treatment is performed once or for a fixed number of times. However, when it is necessary to treat mixed sewage, due to the different types of sewage, the above method cannot be used to determine the amount of flocculant based on factors such as the source of sewage and the amount of sewage. Excessive use of water not only affects water quality, but also leads to waste of flocculant and high cost of water treatment.
针对以上问题，本发明所述的方法对家庭生活中汇总的不同类型的污水统一进行处理，采用进行多次絮凝处理的方法，每次进行絮凝处理前检测水的浊度或电荷量，或者每次进行絮凝处理前同时检测水的浊度和电荷量，根据检测的值确定每次絮凝处理的絮凝剂的投放量，使得现有技术中一次投放絮凝剂的投放量存在的较大误差，被上述多次絮凝处理过程中依据水的检测结果确定每次投放量的方法所修正，既保证了处理后的水质达到要求的同时，又实现了对絮凝剂投放量的精确控制。In view of the above problems, the method of the present invention uniformly treats different types of sewage collected in family life, adopts the method of performing multiple flocculation treatments, and detects the turbidity or charge of the water before each flocculation treatment, or every time Before the first flocculation treatment, the turbidity and electric charge of the water are detected at the same time, and the amount of flocculant for each flocculation treatment is determined according to the detected value, so that there is a large error in the amount of flocculant once in the prior art, which is regarded as The above-mentioned multiple flocculation treatment process is modified by the method of determining the dosage of each time according to the test results of water, which not only ensures that the water quality after treatment meets the requirements, but also realizes the precise control of the dosage of flocculants.
现实生活中，用户对于经过处理后的水质要求并不完全相同，有些用户对于处理后的水质要求较高，大部分用户对于处理后的水通常不会将其用作饮用水，而是满足一些水质要求不高的用途即可，如擦地和冲洗坐便等。要使脏污程度不同的污水经处理后达到某一水质标准，直接影响到水处理效率和处理成本，其差异较大，具体来说，第一种情况，当待处理的污水脏污程度较小时，仅需要进行一次或者少数次絮凝处理、投放少量絮凝剂就可以达到水质要求，此时水处理效率较高、处理成本较低；第二种情况，当待处理的污水脏污程度较高时，需要进行多次絮凝处理、投放大量絮凝剂才可以达到水质要求，此时水处理效率较低和处理成本较高。对于用户来说，将处理水用于水质要求不高的如擦地和冲洗坐便时，第二种情况水处理的效率低且成本高，并不符合用户对于家用水处理经济实惠的要求，此时对于用户来说，待处理的污水过脏已经不具备处理再利用的价值，但是用户无法判断家庭生活汇总的污水是否具备处理再利用的价值。In real life, users have different requirements for the treated water quality. Some users have higher requirements for the treated water quality. Most users usually do not use the treated water as drinking water, but satisfy some It can be used for purposes that do not require high water quality, such as mopping the floor and flushing the toilet. To make sewage with different levels of pollution reach a certain water quality standard after treatment will directly affect the efficiency and cost of water treatment, and the difference is large. Specifically, in the first case, when the level of pollution Hours, only one or a few times of flocculation treatment is required, and a small amount of flocculant can be used to meet the water quality requirements. At this time, the water treatment efficiency is high and the treatment cost is low; in the second case, when the sewage to be treated is highly polluted At this time, multiple flocculation treatments and a large amount of flocculant are required to meet the water quality requirements. At this time, the water treatment efficiency is low and the treatment cost is high. For users, when the treated water is used for low water quality requirements such as mopping the floor and flushing toilets, the efficiency of water treatment in the second case is low and the cost is high, which does not meet the user's requirements for economical and affordable household water treatment. At this time, for the user, the sewage to be treated is too dirty to have the value of treatment and reuse, but the user cannot judge whether the sewage collected from family life has the value of treatment and reuse.
为解决上述问题，本发明通过采用多次投放絮凝剂处理水，并计絮凝处理次数，直到达到设定的条件结束水处理的方法，设定两个优先级条件，第一优先级条件为絮凝处理后水质达到预设定的水质标准，如果水质达标则结束水处理，如果未达标再用第二优先级条件进行判断，直至达到第二优先级条件，则停止水处理并报警，并且在多次投放絮凝剂处理水中，每次絮凝剂的投放量根据投放絮凝剂前检测的水质确定，采用上述方法就可以根据对处理后的水质标准的不同要求以及待处理的污水的脏污程度，进行合理次数的絮凝处理，当待处理的污水过脏不具备处理再利用的价值时，将会停止水处理并报警，这样避免了由于絮凝处理次数过多以及絮凝剂投放过多而造成的水处理效率低，成本高的问题。In order to solve the above problems, the present invention treats water by using the flocculant for many times, and counts the number of times of flocculation treatment, until reaching the set condition to end the water treatment method, sets two priority conditions, the first priority condition is flocculation After treatment, the water quality reaches the preset water quality standard. If the water quality reaches the standard, the water treatment will end. If the water quality does not meet the standard, then the second priority condition will be used for judgment. Each time the flocculant is used to treat the water, the dosage of each flocculant is determined according to the water quality detected before the flocculant is put in. The above method can be used according to the different requirements of the treated water quality standard and the degree of pollution of the sewage to be treated. Reasonable times of flocculation treatment, when the sewage to be treated is too dirty to have the value of treatment and reuse, the water treatment will be stopped and an alarm will be issued, thus avoiding the water treatment caused by too many times of flocculation treatment and too much flocculant The problem of low efficiency and high cost.
其中，设定条件包括：第一优先级条件为絮凝处理后水质达到预设定的水质标准，第二优先级条件为絮凝处理次数达到预设定次数。采用本发明的方法对家用水进行处理时，可根据预期的处理后的水质要求，设定与该水质对应的水的浊度值M或者水中电荷量值Q作为水处理完成的标准，根据用户期望的处理效率与处理成本预设定絮凝处理的次数N，开始处理后，计絮凝处理的次数X，每次絮凝处理后判断是否达到了预设定的絮凝处理的次数N。Wherein, the setting conditions include: the first priority condition is that the water quality after flocculation treatment reaches a preset water quality standard, and the second priority condition is that the number of times of flocculation treatment reaches a preset number of times. When adopting the method of the present invention to process domestic water, according to the expected water quality requirements after treatment, the turbidity value M of the water corresponding to the water quality or the charge value Q in the water can be set as the standard for the completion of water treatment, according to the user Expected treatment efficiency and treatment cost The number of times N of flocculation treatment is preset. After the treatment starts, the number of times X of flocculation treatment is counted. After each flocculation treatment, it is judged whether the number of times N of flocculation treatment has been preset.
如果X＝N，即絮凝处理的次数达到了预设定的次数，则停止水处理并报警，此时说明待处理的污水脏污程度较高，需要进多次絮凝处理并投放大量絮凝剂才可以达到水质要求，此时水处理效率低于用户期望，处理成本高于用户期望，用户收到报警提示后，仍可选择继续进行水处理，如果认为不具备处理再利用的价值时可放弃水处理。If X=N, that is, the number of times of flocculation treatment has reached the preset number of times, the water treatment will be stopped and an alarm will be issued. The water quality requirements can be met. At this time, the water treatment efficiency is lower than the user's expectation, and the treatment cost is higher than the user's expectation. After the user receives the alarm prompt, he can still choose to continue the water treatment. If he thinks that there is no value for treatment and reuse, the water can be discarded. deal with.
如果X<N，即絮凝处理的次数未达到预设定的次数，则每次絮凝处理进行水处理后，检测水的浊度或电荷量，或者检测水的浊度和电荷量，若低于设定的浊度值或电荷量值，或者既低于浊度值也低于电荷量值，则水处理结束，处理后的水达到预期的水质要求；否则继续絮凝处理，直至X＝N，即絮凝处理的次数达到了预设定的次数。If X<N, that is, the number of flocculation treatment does not reach the preset number of times, after each flocculation treatment, the turbidity or charge of the water is detected, or the turbidity and charge of the water are detected. If the set turbidity value or charge value, or is lower than both the turbidity value and the charge value, the water treatment ends, and the treated water meets the expected water quality requirements; otherwise, continue the flocculation treatment until X=N, That is, the number of times of flocculation treatment has reached the preset number of times.
需要说明的是，一次絮凝处理包括投放絮凝剂、进行搅拌、搅拌后静置。其中在本次絮凝处理开始前，根据上一次絮凝处理后检测水的浊度或电荷量，或者同时检测水的浊度和电荷量，根据检测的值确定本次絮凝处理的絮凝剂的投放量。It should be noted that the primary flocculation treatment includes adding a flocculant, stirring, and standing still after stirring. Before the start of this flocculation treatment, the turbidity or charge of the water is detected after the last flocculation treatment, or the turbidity and charge of the water are detected at the same time, and the amount of flocculant for this flocculation treatment is determined according to the detected value .
实施例一Embodiment one
如图1所示，在本实施例中，家用水处理控制方法的具体步骤如下：As shown in Figure 1, in this embodiment, the specific steps of the domestic water treatment control method are as follows:
步骤S101，将污水通入水处理装置并检测水位；Step S101, passing the sewage into the water treatment device and detecting the water level;
步骤S102，达到预设水位值时，停止通入污水并检测水的浊度；Step S102, when the preset water level is reached, stop feeding the sewage and detect the turbidity of the water;
其中，为提高水处理效率，通入的污水的水量达到预设定的水量后再进行絮凝处理，预设定的水量可以由用户直接设定，通入的污水的水量经水处理装置中设置的水位检测装置检测得出，预设定的水量与水处理装置中絮凝处理的容器大小有关。并检测水的浊度记为M1。Among them, in order to improve the efficiency of water treatment, flocculation treatment is carried out after the water volume of the incoming sewage reaches the preset water volume. The preset water volume can be directly set by the user, and the water volume of the incoming sewage is set by the water treatment device The water level detection device detects that the preset water volume is related to the size of the container for flocculation treatment in the water treatment device. And detect the turbidity of water and record it as M1.
步骤S103，根据检测的水的浊度确定初次絮凝处理絮凝剂的投放量，投放絮凝剂；Step S103, according to the detected turbidity of the water, determine the dosage of the flocculant for the primary flocculation treatment, and inject the flocculant;
絮凝剂初次投放量与浊度值M1有关，根据浊度值M1选择对应的絮凝剂投放量，一般的，根据M1所在的区间确定对应的絮凝剂投放量。The initial flocculant dosage is related to the turbidity value M1, and the corresponding flocculant dosage is selected according to the turbidity value M1. Generally, the corresponding flocculant dosage is determined according to the interval where M1 is located.
步骤S104，进行初次絮凝处理，搅拌水处理装置中的水t1时间，再静置t2时间；Step S104, perform initial flocculation treatment, stir the water in the water treatment device for t1 time, and then let stand for t2 time;
絮凝剂投放后，对水进行搅拌，使得絮凝剂快速溶解并均匀分布，生成絮凝物，搅拌预设定的t1时间，停止搅拌后静置t2时间，进一步进行絮凝反应。After the flocculant is put in, the water is stirred, so that the flocculant is quickly dissolved and evenly distributed, and flocs are formed, stirred for a preset time t1, and left to stand for t2 after the stirring is stopped to further carry out the flocculation reaction.
步骤S105，静置后检测的水的浊度值，若低于设定的浊度值，执行步骤S109；否则执行步骤S106；Step S105, if the turbidity value of the water detected after standing still is lower than the set turbidity value, perform step S109; otherwise, perform step S106;

When the measured turbidity value M2 after treatment is less than the set value M, the water quality of the water treatment reaches the standard , the water treatment ends. The treated water is filtered and discharged for other purposes; when the measured turbidity value M2 after treatment is greater than or equal to the set value M, the water quality of the water treatment has not reached the standard at this time, and whether to continue the flocculation treatment needs to be judged whether the number of flocculation treatments is Reach the set value N.
如果X1＝N，即絮凝处理的次数达到了预设定的次数，则停止水处理并报警，此时说明待处理的污水脏污程度较高，不具备处理再利用的价值时可放弃水处理。If X1=N, that is, the number of flocculation treatment reaches the preset number of times, stop the water treatment and give an alarm. At this time, it means that the sewage to be treated is highly polluted, and the water treatment can be abandoned when it does not have the value of treatment and reuse. .
如果X1<N，即絮凝处理的次数未达到预设定的次数，则可继续絮凝处理，再次执行步骤S105，再次执行絮凝处理计次数为X2，直至计数等于N。If X1<N, that is, the number of times of flocculation treatment has not reached the preset number of times, the flocculation treatment can be continued, step S105 is executed again, and the number of times of flocculation treatment is X2 until the count is equal to N.
上述步骤S103至步骤S107为一次絮凝处理，水处理絮凝过程中按上述步骤S103至步骤S107处理重复执行，每处理一次水处理的絮凝处理次数累加一次，至絮凝处理次数达到X＝N时，絮凝处理过程结束；其中，絮凝处理次数N，根据用户期望的处理效率与处理成本确定。The above step S103 to step S107 is a flocculation treatment.

实施例二Embodiment two
在上述实施例的基础上，本实施例所述的方法是将上述检测絮凝后水的浊度值替换为检测絮凝后水的电荷量值，或者既检测絮凝后水的浊度值同时也检测检测絮凝后水的电荷量值，其中浊度与电荷量通过水处理装置中设置的浊度检测装置和电荷检测装置检测得出。On the basis of the above embodiments, the method described in this embodiment is to replace the above-mentioned detection of the turbidity value of the water after flocculation with the detection of the charge value of the water after flocculation, or to detect both the turbidity value of the water after flocculation and also to detect The electric charge value of the water after flocculation is detected, wherein the turbidity and electric charge are detected by the turbidity detection device and the electric charge detection device arranged in the water treatment device.
在絮凝反应过程中，这些脏污粒子会絮凝剂结合在一起形成大的絮凝物。在搅拌的作用下，当絮凝物中包裹较多气体时的其重力小于其所受的浮力，此时絮凝物上升，在絮凝反应桶中水与絮凝物分离的效果。通过大量实验发现，絮凝剂超量投放与絮凝剂欠量投放都会造成水的浊度升高，而当投放量差值超过一定范围时浊度会急剧上升，此时再通过检测絮凝后水的浊度值确定絮凝剂的投放量则会存在较大误差，将影响再一次的絮凝效果或者絮凝剂投放过量造成浪费。During the flocculation reaction, these dirt particles combine with the flocculant to form large flocs. Under the action of stirring, when the flocs are wrapped with more gas, their gravity is less than their buoyancy, at this time the flocs rise, and the water and flocs are separated in the flocculation reaction barrel. Through a large number of experiments, it has been found that the turbidity of the water will increase when the amount of flocculant added and the amount of flocculant under-dosed will increase, and when the difference between the amount of flocculants exceeds a certain range, the turbidity will rise sharply. There will be a large error in determining the dosage of flocculant by the turbidity value, which will affect the flocculation effect again or cause waste due to excessive flocculant dosage.
由于污水中的主要脏污粒子主要有以下成分，泥沙、粘土、不溶性物质以及一些可溶性的盐类等。而这些杂质绝大部分都是带负电荷的粒子，而絮凝剂水解后形成带正电荷的粒子，因此，絮凝剂所带的正电荷能中和水中脏污粒子所带的负电荷，当絮凝剂添加最适量时，水中剩余电荷数为0。所以为解决上述问题，可以在检测水的浊度值的基础上进行水中电荷量的检测，当检测到水中的正电荷过剩时，说明上一次絮凝剂过量投放，当检测到水中负电荷过剩时，说明上一次絮凝剂欠量投放。以该检测结果确定絮凝剂的投放量，可根据检测值范围所对应的适宜的絮凝剂量投放，减少絮凝剂投放量的误差。Because the main dirty particles in the sewage mainly include the following components, silt, clay, insoluble substances and some soluble salts, etc. Most of these impurities are negatively charged particles, and the flocculant is hydrolyzed to form positively charged particles. Therefore, the positive charge of the flocculant can neutralize the negative charge of the dirty particles in the water. When the agent is added to the optimal amount, the residual charge in the water is 0. Therefore, in order to solve the above problems, the detection of the amount of charge in the water can be carried out on the basis of the detection of the turbidity value of the water. When the excess positive charge in the water is detected, it means that the flocculant was excessively injected last time. When the excess negative charge in the water is detected , indicating that the flocculant was under-administered last time. The flocculant dosage can be determined according to the detection result, and the appropriate flocculant dosage corresponding to the detected value range can be used to reduce the error of the flocculant dosage.
