【摘要】 采用人工湿地/稳定塘工艺处理农村生活污水,结果表明,系统对COD、BOD5、SS、TN、NH4+-N、TP和粪大肠杆菌的平均去除率分别达到(75.1%～87.3%)、(75.2%～94.3%)、(90.2%～97.6%)、(50.2%～67.8%)、(65%～75.3%)、(70.6%～85.9%)和98.7%～100%,出水水质达到《污水综合排放标准》(GB8978—1996)的一级标准。该工艺投资少、处理效果好、操作简单、维护成本低。更多还原

【Abstract】 The constructed wetland/stabilization pond process was applied to treat rural domestic sewage.The results show that the average removal rates of COD,BOD5,SS,TN,NH+4-N,TP and faecal coliform bacteria are 75.1% to 87.3%,75.2% to 94.3%,90.2% to 97.6%,50.2% to 67.8%,65% to 75.3%,70.6% to 85.9% and 98.7% to 100% respectively.The effluent quality meets the first class criteria specified in the Integrated Wastewater Discharge Standard(GB 8978-1996).This process has characteristics of low investment,good treatment effect,simple operation and low maintenance cost.更多还原
