技术领域technical field
本发明涉及汽车清洗技术领域，具体涉及一种用于汽车清洗的污水处理系统。The invention relates to the technical field of car cleaning, in particular to a sewage treatment system for car cleaning.
背景技术Background technique
现有洗车行业污水处理系统有如下缺陷：The existing sewage treatment system in the car wash industry has the following defects:
一、一般洗车行店污水处理技术大多采用沉淀、过滤加活性炭吸附工艺，沉淀池占地面积大、容量大(一般沉淀时间要达到4小时以上，沉淀池容量要10立方米以上，不然达不到沉淀的效果)，一般挖坑后混泥土浇筑建设而成，建设成本高昂。1. The sewage treatment technology of general car wash shops mostly adopts sedimentation, filtration and activated carbon adsorption process. The sedimentation tank covers a large area and has a large capacity (generally, the sedimentation time should be more than 4 hours, and the capacity of the sedimentation tank should be more than 10 cubic meters, otherwise it will not reach To the effect of sedimentation), it is generally constructed by pouring concrete after digging a pit, and the construction cost is high.
二、建设场地必须要连接进水管网和排放污水的管网以及相关的行政许可手续。2. The construction site must be connected to the water inlet pipe network and the sewage discharge pipe network, as well as related administrative licensing procedures.
三、过滤器精度一般为5微米到50微米，有些还不配置过滤器，不能过滤微生物和有机物，洗车液中有机物和细菌没有办法去除，过滤器冲洗水没有经过处理直接排放。3. The filter precision is generally 5 microns to 50 microns. Some of them are not equipped with filters, which cannot filter microorganisms and organic matter. There is no way to remove organic matter and bacteria in car wash liquid, and the filter rinse water is discharged directly without treatment.
四、吸附罐中的砂虑材料更换时一般都直接丢弃或不装填。由于成本原因，活性炭一般装填容量不够或者根本就不装填。4. When the filter material in the adsorption tank is replaced, it is generally discarded directly or not filled. Due to cost reasons, activated carbon is generally not filled enough or not filled at all.
五、清除沉淀物必须进行人工清除，清除时必须先要把沉淀池的水抽干排放后才能进行清除作业。清除出来的沉淀物含水率高，呈泥浆状态，少部分进入城市垃圾系统，绝大部分排入下水道管网系统。5. To remove the sediment, it must be removed manually. When removing it, the water in the sedimentation tank must be drained before the removal operation can be carried out. The removed sediment has a high moisture content and is in the state of mud. A small part enters the municipal waste system, and most of it is discharged into the sewer pipe network system.
六、活性炭吸附可以吸附部分微生物细菌和有机物，但是由于成本原因，活性炭填装容量普遍偏少，或者根本就不装活性炭，即便按照设计要求填装了活性炭，在洗车污水高含量洗车液、高含量车蜡、高含量固体颗粒、油脂、有机磷等有机物的情况下，活性炭一般使用几天就已经饱和，就根本起不到吸附的目的，造成洗车水异味发臭、酸化的情况发生，洗车场不得不排放洗车循环水，添加或更换新水才能进行正常洗车作业，排放的洗车循环水中的污染物直接进入城市下水道，对环境有极大的污染。如果活性炭按照要求进行定期更换或者从新活化，成本高昂，洗车店经济上是不能接受的，并且生产或活化活性炭的过程本身就是对资源的浪费和环境的污染。所以现在的洗车行业存在以下缺陷或不足。6. Activated carbon adsorption can adsorb some microorganisms, bacteria and organic matter. However, due to cost reasons, the filling capacity of activated carbon is generally too small, or no activated carbon is installed at all. In the case of high content of car wax, high content of solid particles, grease, organic phosphorus and other organic substances, the activated carbon is generally saturated after a few days of use, and it cannot achieve the purpose of adsorption at all, resulting in odor and acidification of the car wash water. The field has to discharge the car washing circulating water, and add or replace new water to carry out normal car washing operations. The pollutants in the discharged car washing circulating water directly enter the urban sewer, which has great pollution to the environment. If the activated carbon is regularly replaced or reactivated according to the requirements, the cost is high, and the car wash shop is economically unacceptable, and the process of producing or activating activated carbon itself is a waste of resources and environmental pollution. Therefore, the following defects or deficiencies exist in the current car washing industry.
七、消耗巨大的水资源，洗车店一般每辆车洗车排放污水30-50升左右，2018年1月全国有53个城市的小汽车保有量超过100万辆，24个城市超过200万辆，7个城市超过300万辆，而且每年还在以超过10％的速度增长，现在按照中国50个中等以上城市平均200万辆家用轿车，每个月洗车一次计算，每年将消耗掉30升/辆车*200万辆车/城市*12月*50个城市＝3600万立方米水资源，同时也排放了3600万立方米的洗车污水，每年不光消耗了大量水资源，同时污水排放也对环境产生极大的影响。7. Huge consumption of water resources. Car wash shops generally discharge about 30-50 liters of sewage per car wash. In January 2018, there were 53 cities across the country with more than 1 million cars and 24 cities with more than 2 million cars. There are more than 3 million cars in 7 cities, and it is still growing at a rate of more than 10% every year. Now, based on the average of 2 million family cars in China's 50 cities above the middle level, the car wash once a month will consume 30 liters per car per year Cars * 2 million vehicles/city * December * 50 cities = 36 million cubic meters of water resources, and also discharge 36 million cubic meters of car wash sewage, which not only consumes a lot of water resources every year, but also pollutes the environment. huge impact.
八、液体废物(洗车液、车蜡、油脂、有机磷、微生物等有机物)不能进行单独收集，随污水排放到城市污水管网系统，对环境有极大影响。8. Liquid waste (car wash liquid, car wax, grease, organic phosphorus, microorganisms and other organic matter) cannot be collected separately, and will be discharged into the urban sewage pipe network system along with the sewage, which will have a great impact on the environment.
九、固体废物不能自动收集，含水率高，呈泥浆状态，人工收集后极少部分进入城市垃圾系统外，绝大部分还是随污水排放到城市污水管网系统，污染环境。9. Solid waste cannot be collected automatically. It has a high water content and is in a muddy state. After manual collection, a very small part enters the urban waste system, and most of it is discharged to the urban sewage pipe network system with sewage, polluting the environment.
十、污水处理中过程成本高，特别是活性炭的生产或者再生过程既消耗资源，也对环境有影响。10. The process cost of sewage treatment is high, especially the production or regeneration process of activated carbon not only consumes resources, but also has an impact on the environment.
十一、循环用水不能长时间重复循环使用，洗车店必须建设在有进水和污水排放管网条件的地方。连接进水和污水排放管网，办理用水和污水排放许可，增加了建设难度和成本。11. Circulating water cannot be reused for a long time. Car wash shops must be built in places with water inlet and sewage discharge pipe network conditions. Connecting the water intake and sewage discharge pipe network, and applying for water and sewage discharge permits increase the difficulty and cost of construction.
综上，现有自动洗车技术的水资源循环利用效率不高。In summary, the water recycling efficiency of the existing automatic car washing technology is not high.

根据洗车区集水池中的水位高低将洗车污水抽到调节水箱中，调节水箱中的污水经过水泵加压后进入第一过滤器、第二过滤器和第三过滤器进行过滤，经过滤器过滤器后分为过滤水和过滤器冲洗水两部分进行处理：According to the water level in the sump of the car washing area, the car washing sewage is pumped into the regulating water tank. After being pressurized by the water pump, the sewage in the regulating water tank enters the first filter, the second filter and the third filter for filtration. Finally, it is divided into two parts: filtered water and filter flushing water for treatment:
第一部分，过滤器过滤水的处理，洗车污水经过过滤器中空纤维精滤滤芯进行过滤，过滤精度为0.01微米，过滤后的过滤水清洁度已经能达到洗车用水要求，但是还含有少部分洗车液、水蜡、微生物、有机物，将这部分过滤水进入气浮破泡消毒灭菌水箱，进行有机物微生物的杀灭和气浮收集去除，微生物的杀灭利用水中紫外线灯光进行，洗车液、水蜡、微生物等有机物的去除利用压缩空气气浮产生的气泡带到水面，然后利用气泡收集和破泡成液体废物收集进入液体废物收集箱，液体废物收集箱有重量传感器，会通过远程监控系统自动发送废物清理信息。该部分洗车污水经过过滤、微生物杀灭、有机物分离收集后，进入洗车储水箱进行酸碱度检测和调节，这样处理过的污水能够达到洗车用水的要求。这部分污水由于经了过滤、微生物杀灭、有机物去除、酸碱度调节处理，长时间循环使用也不会发生异味、酸化等不良现象。The first part is the treatment of filter water. The car wash sewage is filtered through the hollow fiber fine filter element of the filter. The filtration accuracy is 0.01 microns. The cleanliness of the filtered water after filtration has reached the requirements of car wash water, but it still contains a small amount of car wash liquid. , water wax, microorganisms, and organic matter, this part of the filtered water is put into the air flotation foam-breaking disinfection and sterilization water tank, and the organic matter and microorganisms are killed and air flotation is collected and removed. The microorganisms are killed by ultraviolet light in the water. The removal of microorganisms and other organic matter is brought to the water surface by the air bubbles generated by compressed air flotation, and then the bubbles are collected and broken into liquid waste and collected into the liquid waste collection box. The liquid waste collection box has a weight sensor and will automatically send the waste through the remote monitoring system Clear information. This part of the car washing sewage is filtered, microorganisms are killed, and organic matter is separated and collected, and then enters the car washing water storage tank for pH detection and adjustment, so that the treated sewage can meet the requirements of car washing water. Because this part of sewage has been treated by filtration, microbial killing, organic matter removal, and pH adjustment, it will not cause odor, acidification and other adverse phenomena after long-term recycling.
第二部分，过滤器冲洗水的处理，过滤器的冲洗水处理第一步进入沉淀水箱进行混凝沉淀，在沉淀水箱中加入沉淀剂，经过一定时间沉淀的上部污水进入调节水箱，再次进入污水处理系统。沉淀水箱的下部的沉淀物间歇通过旋转排污阀送入皮带脱水机进行脱水，脱水后的固体废物落入固体废物收集箱，固体废物收集箱有重量传感器，达到一定重量自动远程通知进行清理。皮带脱水机脱水过程中的分离水进入调节水箱，从新进入污水处理系统进行处理。The second part is the treatment of the filter flushing water. The first step of the filter flushing water treatment is to enter the sedimentation tank for coagulation and sedimentation. A precipitant is added to the sedimentation tank. After a certain period of precipitation, the upper sewage enters the adjustment tank, and then enters the sewage again. processing system. The sediment in the lower part of the sedimentation tank is intermittently sent to the belt dehydrator through the rotary drain valve for dehydration, and the dehydrated solid waste falls into the solid waste collection box. The solid waste collection box has a weight sensor, and when it reaches a certain weight, it will be automatically notified remotely for cleaning.

Controller connection.
气浮破泡装置是利用压缩空气经过箱底的气管上的气孔进入水中，水中的洗车剂、水蜡、微生物等有机物随气泡一起带到水面，并高出水面一定高度进入破泡箱，气泡进入破泡箱后进行自然破裂，当泡沫的高度达到一定高度时，通过气泡高度检测传感器向高压电发生器控制箱发送信号，产生高压电，通过破泡箱中的高压电极间歇放电产生电火花使泡沫变成液体，顺着破泡箱底部流入液体收集箱中。同时在气浮破泡装置中装有紫外线光灯管，将水中的微生物杀死后经气泡带到水面，随气泡进入液体废物收集箱，达到了对洗车水进行消毒、杀菌、去除洗车液、水蜡、油脂和有机物消除异味的目的，并能保证洗车用水的长期循环使用。The air flotation foam breaking device uses compressed air to enter the water through the air holes on the air pipe at the bottom of the tank, and the car wash, water wax, microorganisms and other organic substances in the water are brought to the water surface together with the air bubbles, and enter the bubble breaking tank at a certain height above the water surface, and the air bubbles enter After breaking the bubble box, it will be broken naturally. When the height of the foam reaches a certain height, the bubble height detection sensor will send a signal to the high-voltage generator control box to generate high-voltage electricity. The spark turns the foam into a liquid, which flows down the bottom of the bubble breaker into the liquid collection tank. At the same time, an ultraviolet light tube is installed in the air flotation bubble breaking device, which kills the microorganisms in the water and brings them to the water surface through the air bubbles, and enters the liquid waste collection box with the air bubbles, so as to disinfect and sterilize the car wash water, remove the car wash liquid, Water wax, grease and organic matter eliminate odor, and can ensure the long-term recycling of car wash water.
利用泡沫高出水面的高度由泡沫的特性决定外，还由气流上升的速度与泡沫在上升通道中的自然破裂速度的比值决定，比值越大泡沫高出水面高度的越高的原理，在水面上部设立专门的破泡箱，破泡箱底部封闭，上口高出水面一定高度，破泡箱中设立一定直径的短管作为泡沫上升引导筒，与破泡箱上口齐平，利用气泡在短管道中的快速上升，将气泡带到上部破泡箱中，破泡箱上部面积大，气流不再快速上升，泡沫在破泡箱中自然破裂成液体，当泡沫自然破裂速度慢到泡沫高度高于设定高度时，传感器发出信号，启动高压电发生器产生高压电，使高压电极放电，利用电火花强制泡沫破裂成液体，然后通过破泡箱外缘底部的管道流入液体废物收集箱，完成破泡目的。The height of the foam above the water surface is determined not only by the characteristics of the foam, but also by the ratio of the rising speed of the airflow to the natural bursting speed of the foam in the ascending channel. The larger the ratio, the higher the height of the foam above the water surface. A special bubble-breaking box is set up on the upper part, the bottom of the bubble-breaking box is closed, and the upper opening is a certain height above the water surface. A short tube with a certain diameter is set in the bubble-breaking box as a foam rising guide tube, which is flush with the upper opening of the bubble-breaking box. The rapid rise in the short pipe brings the bubbles to the upper bubble breaking box. The upper area of the bubble breaking box is large, the air flow no longer rises rapidly, and the foam naturally breaks into liquid in the bubble breaking box. When the height is higher than the set height, the sensor sends a signal to start the high-voltage generator to generate high-voltage electricity, so that the high-voltage electrodes are discharged, and the foam is forced to break into liquid by electric spark, and then flows into the liquid waste collection through the pipe at the bottom of the outer edge of the bubble breaking box Box to complete the purpose of breaking bubbles.
