A scattered rural areas because of the residents, mass concentration sewage collection is difficult, also meet the requirement of discharging standard has always been a difficult problem. Therefore, west dongting district in the construction of the first in the province more than the "micro" sewage treatment station, each site is responsible for the collection processing, an area near sewage in this rural green lung, to ensure that the sewage discharging standard.
In west dongting district wish xinfeng Peng Jiazhou village, canna, calamus grew just within the sewage treatment station, the roots of the plants, can adsorption rich nutrients in sewage, the effect of bioremediation. Here, the area surrounding the sewage collection into the sump, first to precipitate removal of solid impurities, deoxidized by microbial phosphorus removal again, and then went into artificial wetland for sand filter, plant adsorption, processing to the standard after discharge of the field ditch.

Water is 20 milligrams per liter of ammonia nitrogen, water is 5 mg per liter of ammonia nitrogen, the effect of sewage treatment is up to standard.
Peng Jiazhou sewage treatment station of life, the daily sewage treatment capacity can reach more than 200 tons, covering more than 2500 rural residents. At the same time, the rural small sewage treatment station, due to realize the miniaturization of the sewage treatment equipment, covers an area of less, low energy consumption, can provide electricity by the photovoltaic panel, greatly reduces the operating costs, reduce the burden on farmers.

At present, the construction of west dongting administrative zone 5 such micro power sewage treatment station, and 1 large centralized sewage treatment plants, more than 5300 sets of retail sewage treatment system, makes the entire district eight village life wastewater treatment rate reached 84.5%. Next, west dongting district will also vigorously promote "micro" rural sewage treatment mode, make the rural "green lung" beautiful country.
