技术领域technical field
本发明涉及生活垃圾处理技术领域，尤其涉及一种集成处理系统。The invention relates to the technical field of domestic waste treatment, in particular to an integrated treatment system.
背景技术Background technique
随着我国城镇化建设和国民经济的发展，城乡居民生活中排放的垃圾和污水也越来越多，严重影响居民的生活环境。目前，处理城乡居民生活排放的垃圾及污水的方法，大多分开处理，其中，对于固体垃圾，通常是收集、运输、集中到垃圾填埋场填埋，或者直接焚烧；对于液体垃圾(污水)，则是通过修建污水收集管网系统，将污水引流至污水处理厂进行处理。对于这种处理方法，无论是固体垃圾的运输，还是污水处理厂的修建，均需花费大量人力和巨额资金。With the development of my country's urbanization and national economy, more and more garbage and sewage are discharged in the lives of urban and rural residents, seriously affecting the living environment of residents. At present, most of the methods for dealing with the garbage and sewage discharged by urban and rural residents are treated separately. Among them, for solid waste, they are usually collected, transported, concentrated in landfills, or directly incinerated; for liquid garbage (sewage), It is through the construction of a sewage collection pipe network system to divert the sewage to the sewage treatment plant for treatment. For this treatment method, whether it is the transportation of solid waste or the construction of sewage treatment plants, a lot of manpower and huge funds are required.
另外，对于农村生活环境，由于我国有些农村地区山地繁多、农户居住分散，难免造成餐厨垃圾、人(畜)排泄物、生物质等各种固体垃圾和生活污水的散排。受农村环境和地理因素影响，无论是固体垃圾的收集和运输，还是污水处理厂的修建，都难以实现。而且，固体垃圾和污水分别单独处理本身就是比较复杂的处理过程。若农村生活垃圾不能集中起来处理，不仅会影响农村的生活环境，而且，垃圾中的有机物很容易滋生病菌，必然会对当地人们的健康造成一定的影响。In addition, for the rural living environment, due to the many mountainous areas in some rural areas of our country and the scattered living of farmers, it is inevitable to cause the scattered discharge of various solid wastes such as kitchen waste, human (animal) excrement, biomass, and domestic sewage. Affected by the rural environment and geographical factors, it is difficult to realize whether it is the collection and transportation of solid waste or the construction of sewage treatment plants. Moreover, the separate treatment of solid waste and sewage is a relatively complicated process in itself. If the domestic waste in rural areas cannot be treated together, it will not only affect the living environment in the countryside, but also, the organic matter in the waste can easily breed germs, which will inevitably have a certain impact on the health of local people.

The biochemical reaction device 100, the waste liquid treatment unit 200, and the biological purification device 250 are sequentially connected through pipelines.
农村环境中排放的生活垃圾包括生活污水、餐厨垃圾、人(畜)排泄物、生物质等，这些生活垃圾可分流输送至生化反应装置100中进行生化反应处理。The domestic waste discharged in the rural environment includes domestic sewage, kitchen waste, human (animal) excrement, biomass, etc., and these domestic waste can be diverted and transported to the biochemical reaction device 100 for biochemical reaction treatment.
另外，集成处理系统300还包括搅拌装置310，生活垃圾中的预定部分在经搅拌装置310搅拌之后再导入到生化反应装置100中进行生化反应处理。具体地，生活垃圾中的预定部分包括生物质、餐厨垃圾等固体类垃圾。换言之，生物质、餐厨垃圾等固体类垃圾在进入生化反应装置100之前，先输送至搅拌装置310中进行搅拌、粉碎后，进而导入生化反应装置100中与生活污水、人(畜)排泄物等垃圾混合，并在该生化反应装置100内进行生化反应处理。In addition, the integrated treatment system 300 also includes a stirring device 310 , after being stirred by the stirring device 310 , a predetermined part of the domestic waste is introduced into the biochemical reaction device 100 for biochemical reaction treatment. Specifically, a predetermined part of domestic waste includes solid waste such as biomass and kitchen waste. In other words, before entering the biochemical reaction device 100, solid waste such as biomass and kitchen waste is transported to the stirring device 310 for stirring and crushing, and then introduced into the biochemical reaction device 100 to be mixed with domestic sewage and human (animal) excrement. and other wastes are mixed, and biochemical reaction treatment is carried out in the biochemical reaction device 100.

In addition, the main component of the waste gas obtained after being treated by the biochemical reaction device 100 is methane, and the methane can be reused.
进一步地，生化反应装置100内适于添加配料，配料包括原料、接种物、菌种、以及酶类等反应物，但不限于此。这样，被输送至生化反应装置100中的生活垃圾会与配料进行混合，从而在生化反应装置100内进行生化反应，反应后得到可达标排放的废气、废渣，以及待进一步处理的废液。Further, the biochemical reaction device 100 is suitable for adding ingredients, and the ingredients include raw materials, inoculum, bacteria, and enzymes and other reactants, but are not limited thereto. In this way, the domestic garbage transported into the biochemical reaction device 100 will be mixed with the ingredients, so as to undergo a biochemical reaction in the biochemical reaction device 100, and after the reaction, waste gas, waste residue, and waste liquid to be further processed can be obtained.

In addition, the oil separation and acidification tank 210 is also suitable for adding organic matter according to the water quality of the introduced waste liquid, so as to carry out sedimentation and sterilization treatment on the waste liquid in the oil separation and acidification tank 210 . Optionally, the organic matter includes a flocculant and/or a bactericide, and the flocculant may be polyacrylamide, but is not limited thereto. According to one embodiment, the oil-separating acidification tank 210 includes an oil-water separator (not shown in the figure), and oil-separating treatment is performed on the waste liquid through the oil-water separator. The oil-water separator can achieve the purpose of oil-water separation by utilizing the different specific gravity of suspended solids and water in the waste liquid.

The second biofilm aeration tank 230 is in communication with the first biofilm aeration tank 112 , and the waste liquid treated by the first biofilm aeration tank 220 is continuously introduced into the second biofilm aeration tank 230 for treatment. The sedimentation tank 240 communicates with the second biofilm aeration tank 230 and the biological purification device 250 respectively, and the waste liquid treated by the second biofilm aeration tank 230 continues to be introduced into the sedimentation tank 240 for sedimentation treatment. Here, the sedimentation tank 240 separates the waste liquid into sludge and sewage after sedimentation treatment. The sludge can be directly discharged up to the standard, and the sewage can be continuously introduced into the biological purification device 250 for further purification and then discharged.
需要说明的是，若经废液处理单元200的沉淀池240处理后得到的污水满足《城镇污水综合排放标准(GB18918-2002)》二级标准，则可直接达标排放，而不用导入生物净化装置250中进一步净化。It should be noted that if the sewage obtained after being treated by the sedimentation tank 240 of the waste liquid treatment unit 200 meets the secondary standard of the "Comprehensive Discharge Standard for Urban Sewage (GB18918-2002)", it can be directly discharged up to the standard without introducing a biological purification device 250 for further purification.

The sewage in the sedimentation tank 240 is suitable for flowing into the valve 245, and the sewage is sampled and tested at the valve 245, and it is determined whether to discharge the sewage according to the test result. If the sewage test is up to standard, then it can be directly discharged through the pipeline connected with the valve 245, without being introduced into the biological purification device 250 for further purification; The biological purification device 250 further filters and purifies the sewage and then discharges it.
