A/O+人工湿地工艺处理四川丘陵地区农村生活污水应用
Study on Treatment of Rural Domestic Sewage in Sichuan Hilly Area by A/O + Artificial Wetlands
摘要
Abstract
[Objective] To analyze the topography of Sichuan hilly areas and the characteristics of rural domestic sewage in reconstruction region. [ Method] The methods of A/O and artificial wetlands were combined to treat rural domestic sewage. [ Result] Operating at 22 h hydraulic retention time of A/O and a hydraulic loading rate of 0.6 Mv(m2 · H) ,under the average concentrations of COD≤60 mg/L,NH3 -N≤8 mg/L,TP ≤1.0 mg/L,SS≤20 mg/L in the effluent, the average removal efficiencies of COD,NH3 - N,TP and SS were 81. 4% ,84. 1% ,83. 3% and 90.0% ,respectively. [ Conclusion ] The effluent indexes could reach the first level B discharge criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918 -2002).关键词
