Technical Field
The utility model relates to a sewage treatment technical field, concretely relates to novel sewage treatment integration equipment.
Background
The rural domestic sewage treatment is an important content for improving rural living environment and improving the living standard of rural residents, and is also an important mark for rural modernization. Along with the improvement of the rural living standard, the water-flushing toilet is popularized among farmers, the washing water is increased, the domestic water consumption and the centralized water supply rate in rural areas are increased year by year, and the discharge amount of the rural domestic sewage is increased year by year. In 2015, 7.97 hundred million rural population in China is estimated according to 83L of daily domestic water consumption per capita and 0.8 of discharge coefficient, and 193 billion cubic meters of rural domestic sewage is accumulated all year round and needs to be treated, and accounts for 31 percent of the total domestic sewage discharge amount in China. From the aspect of treatment rate, the treatment rate of municipal sewage is 91.9% at the end of 2015, and the total amount of sewage treatment reaches 428.8 billion cubic meters. The county and city sewage treatment rate is 85.22%, and the total annual sewage treatment amount reaches 78.9 billion cubic meters. The treatment rate of the sewage in the administrative village is 11.4 percent, and a large amount of domestic sewage in the rural village is discharged without treatment, so that the sewage becomes one of the main causes of environmental pollution such as eutrophication of the rural villages, lakes and rivers. At present, China actively and steadily promotes new rural construction, accelerates improvement of living environment, improves quality of farmers in China, and promotes pace of new rural construction. Rural sewage treatment is more and more emphasized, and the construction of beautiful villages does not leave the overall improvement of rural environments. Under the background of 'five-water co-treatment and people participation' proposed by the government in Zhejiang, the problems of wide coverage, high treatment difficulty, more complex treatment conditions, weak rural sewage treatment foundation and the like in rural domestic sewage treatment are found. Most rural areas lack drainage and sewage treatment systems, a large amount of domestic sewage and domestic wastewater are directly discharged into rivers and ponds, water environment pollution and water eutrophication are caused to a great extent, and living environments of the rural masses are influenced.
Development of rural domestic sewage treatment is an important work for improving water environment quality in rural areas. Compared with cities, the treatment of rural domestic sewage has the following characteristics: because the rural economic foundation is relatively weak, the control cost for water pollution is low; the matched infrastructure is poor, and corresponding detection facilities and monitoring personnel are not available; the scale of a single sewage treatment facility is small, but the facility quantity is huge, and the operation and supervision difficulty is large. According to the analysis result of data in 2010 < national urban and rural construction statistics yearbook >, the treatment rate of urban sewage in China reaches 87%, the treatment rate of sewage in county and city reaches 75%, the treatment rate of sewage in construction town reaches 28%, but the treatment rate of sewage in rural area is only 8%. However, under relevant policies and environmental conditions, rural sewage treatment issues have been promulgated and have evolved rapidly with national financial support. According to statistics, the treatment rate of domestic sewage in rural areas in the country in 2016 reaches 22%, but due to the fact that most of rural economic levels are relatively laggard, capital is deficient, investment is insufficient, technical strength is weak, rural residences are scattered, only the traditional urban sewage treatment technology and process are simply applied, and capital cost is generally 1500-2000 yuan/m3(ii)/d, total treatment cost is 0.7-3.0 yuan/m3And rural areas are not affordable due to economic constraints.

Patent 201510183884.3 discloses a decentralized sewage treatment method in rural areas, which is characterized in that the facility consists of a regulating tank and an integrated facultative membrane bioreactor, and adopts continuous water inlet, periodic aeration and periodic water drainage. Patent 201610424762.3 discloses an OMBR integration sewage treatment retrieval and utilization device, its characteristic includes multiple high-efficient biological purification pond, buffer tank, high-efficient sedimentation tank, OMBR pond, backwash pond, adds medicine disinfection system and circulation pond. However, in general, these processes involving membrane treatment technologies have the disadvantages of high energy consumption, high maintenance cost, high replacement cost of membrane materials, high technical requirements for operators, and the like.
According to the development level of rural productivity in China and the characteristics of rural natural climate, relevant organizations put forward that the technology and facilities for treating rural domestic sewage in China should meet four basic requirements of low cost, less maintenance, ecology and good effect.
