Demonstration Project of Domestic Sewage Decentralized Treatment in Dongsheng Village, Kangping County, Shenyang City

Project Background

Every family in Dongsheng Manchu and Mongolian Townships in Kangping County has a big yard, and most of the villagers have the habit of raising cattle and sheep in their yard. In the summer, flies are unavoidable, and sewage flows and even pollutes the groundwater.

With little rain and water, the villagers in Kangping have been drinking from their own small wells for a long time. This kind of shallow surface water is seriously polluted and has very pool quality. It also needs to settle for several hours before boiling.

The domestic sewage after toilet modification in this area contains relatively high concentration of pollutants such as CODCr, BOD5 and TN. Once these pollutants directly enter the natural environment, they will have potential impact on the surrounding ecology. The pollution sources of farmers in this area are relatively scattered, no supporting pipe network is built. Thanks to the relatively concentrated residents, it is convenient for laying the pipe network. Therefore, a centralized sewage treatment terminal should be constructed to treat the domestic sewage generated.

Solution

For domestic sewage treatment in such areas, we adopt small integrated sewage treatment equipment to treat sewage, which can effectively address the problem of domestic sewage treatment in this area. The quality of the treated water has reached the Grade B in the "Discharge standard of pollutants for municipal wastewater treatment plant" GB18918-2012, which can be directly discharged into natural water bodies or reused for farmland irrigation in the area.
