The design is feasible in technology and reasonable in economic. The investment cost is about RMB 502 million and the treatment cost of per ton water is RMB 0.24 yuan / day. The entire design process can use less area. The design has the advantages of less cost, stable operation, less secondary pollution to ensure that the treatment water achieves water standard, disposal with good effect, simple process, covering less area, stable operation and less energy consumption.
The treated water is excepted to achieve the effluence standard in the country, which is as 
following: COD≤100mg/L ,BOD≤30mg/L, SS≤30mg/L, TN≤35mg/L, NH3-N≤20mg/L, TP≤3mg/L according to the《Municipal wastewater treatment plant emission standards(GB 18918-2002). It is estimated to reduce discharging to environment each year CODcr 98600ton. aEnvironmental benefits and social benefits are obvious. It will increase the ratio of removal in Shanghai. It will give full play and show the functions completely of defending water body.
