摘　　要：设计了一种模块化生物滤池—人工湿地相结合的农村生活污水处理新工艺。通过实验研究,探讨了脱氮池、模块化生物滤池和人工湿地在不同运行条件下对COD,NH_(4)^(+)-N,TN,TP等污染物的去除效果。实验结果表明:在回流比300%、布水时间2 min、布水间歇8 min条件下,模块化生物滤池—人工湿地组合工艺对COD,NH_(4)^(+)-N,TN,TP去除率分别达到87.76%,93.62%,89.03%,92.76%,出水水质均符合贵州省DB 52/1424—2019《农村生活污水处理水污染物排放标准》一级排放标准。为农村生活污水处理提供了一种高效、稳定的解决方案,具有良好的应用前景。A novel rural domestic wastewater treatment process combining a modular biofilter with a subsurface flow constructed wetland was designed.This study systematically investigated the removal efficiencies of COD,NH_(4)^(+)-N,TN,and TP under varying operational conditions in the denitrification tank,modular biofilter,and constructed wetland.Results showed that at a reflux ratio of 300%,a water distribution time of 2 minutes,and an interval of 8 minutes,the combined system achieved removal efficiencies of 87.76%,93.62%,89.03%,and 92.76%for COD,NH_(4)^(+)-N,TN,and TP,respectively.The effluent quality consistently met the Grade A discharge standards of DB 52/1424-2019 for rural domestic sewage treatment in Guizhou Province.This study provides an efficient and stable solution with promising application prospects for rural wastewater management.
