Abstract:
The combined process of anoxic/oxic(AO), membrane bioreactor(MBR) and vertical flow constructed wetlands(VFCW) was adopted to design a domestic sewage treatment project in Batou Village, Luoyang Town, Changzhou City. The removal effects of COD, ammonia nitrogen, total nitrogen, total phosphorus were investigated and the results of one?year project operation show that the average removal rates of them can reach 84%, 97%, 84% and 83%, respectively, and the effluent concentration can reach the requirements of Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area (DB 32/1072-2018). The total investment of the pipeline network and equipment of the demonstration project is about 1.162 5 million yuan, and the operating cost is about 1.125 yuan/m3, which has the advantages of lower investment cost, less operation and maintenance costs, higher ecological and environmental benefits, etc.
