摘　　要：根据农村生活污水的特点,采用格栅-隔油池-1#表流人工湿地-潜流人工湿地-2#表流人工湿地的方法处理了农村生活污水,处理规模100 m^(3)/d,进水水质COD为200~250 mg/L、BOD_(5)为100~125 mg/L、NH_(3)-N为25~30 mg/L、SS为100~150 mg/L、TP为2~3 mg/L。结果表明:处理后出水水质满足河南省地方标准《农村生活污水处理设施水污染排放标准》(DB41/1820-2019)一级标准。该工艺具有投资小、出水水质稳定、具有景观效果等优点,同时减少了农村生态环境的污染。可供参考。According to the characteristics of rural sewage,the combined process of grid,oil separation tank,1# surface flow constructed wetland vertical subsurface flow constructed wetland and 2# surface flow constructed wetland was used to treat rural domestic sewage with a treatment capacity of 100 m^(3)/d.The influent COD,BOD5,NH_(3)-N,SS and TP are 200 to 250 mg/L,100 to 125 mg/L,25 to 30 mg/L,100 to 150 mg/L and 2 to 3 mg/L.After treatment,the effluent quality meet the first level standard in the Discharge Standard for Water Pollution of Rural Domestic Sewage Treatment Facilities(DB41/1820-2019)of Henan provincial local standard.The combined process has the advantages of small investment,stable effluent quality,landscape effect and reduced the pollution of the ruralecological environment.
