- Abstract:
- The project scale of Shenshuiwan wastewater treatment plant in Shenyang City is 200 000 m3/d. It covered an area of 6.58 hm2, and originally adopted FLOOBED technology. The current effluent was subject to the secondary standard of Integrated Wastewater Discharge Standard (GB 8978-1996). The terminal water discharged directly into Hunhe River. In order to reduce the pollution to the receiving water and raise the effluent standard to the first class A standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), the wastewater treatment plant was upgraded. The upgrading project adopted anaerobic zone + anoxic zone + aerobic zone with filler(A2/O-MBBR process), built new anaerobic and anoxic tank, transformed the present biochemical tank into aerobic MBBR tank, and transformed the blower room and aeration system, etc. After upgrading and reconstruction, the effluent indicators stably met the design standard, the operating cost was only 0.373 yuan/m3.
