Research On Rural Sewage Treatment Technology In Mei County

With the popularity of tap water, sanitary ware, the use of solar energy water heater andflush toilets, rural sewage emissions increase greatly; while the lag of wastewater collectionand treatment facilities and lack of planning and technical guidance problems tend to be moreserious water pollution in rural area. There are sewage dispersion、complex terrain、pooreconomic conditions and other characteristics in rural areas, applying the method of Terminaltreatment of urban wastewater is inappropriate. Therefore, finding practical applicable sewagetreatment technologies has become important ways to solve the rural sewage treatment.For the rural domestic sewage pollution control, this paper presents three kinds ofcollection, including the collection mode, decentralized collection mode and pipe networksewage collection mode; three types of best feasible rural sewage treatment: biologicaltreatment technologies, eco-technology and physico-chemical treatment technologies.Biological treatment technology is divided into aerobic biological treatment technology(activated sludge, biological contact oxidation, membrane bioreactor) and anaerobicbiological treatment (anaerobic fermentation, anaerobic filter method, the three formatsseptic tank law); ecological treatment technologies include artificial wetland law, landtreatment and stabilization pond method; physico-chemical treatment method mainly ruralsewage coagulation technology.When you select wastewater treatment technology, based on low cost, easy to use, stablewater quality principle, combined with the local land resources, wastewater characteristics,climatic conditions, the main crops and local environmental requirements, the actual situationof sewage discharges, choose the best technologies to safeguard rural sewage treatment workscan be stable, good implementation and operation.This article relies on the Shaanxi province rural environment comprehensive treatmentproject, sewage treatment facilities for sewage treatment Baoji Meixian2013villageconstruction as the research object, using data collection, field surveys and other methods, toanalyze the rural sewage treatment in Meixian county. Guo He and Dong Jia shan village, forexample, under the basis of the existing sewage treatment facility, according to the populationsize, topography, water environment functional requirements and so on, design the programfrom the location of sewage treatment facilities, treatment process selection, facilityparameter estimation and investment.
