为了实现农村分散式污水处理工艺节约占地面积、稳定净化效果、简化管理、降低运行和建设费用的目标,采用厌氧/好氧/人工湿地组合工艺进行工程设计。在各污水处理设施运行良好的情况下,污水经人工湿地组合工艺处理后,出水水质各项指标达到《城镇污水处理厂污染物排放标准》一级B的排放标准。
為瞭實現農村分散式汙水處理工藝節約佔地麵積、穩定淨化效果、簡化管理、降低運行和建設費用的目標,採用厭氧/好氧/人工濕地組閤工藝進行工程設計。在各汙水處理設施運行良好的情況下,汙水經人工濕地組閤工藝處理後,齣水水質各項指標達到《城鎮汙水處理廠汙染物排放標準》一級B的排放標準。

In order to meet the technical requirements of smaller occupancy area , good treatment effect, easier maintenance and lower operation and construction cost in the treatment of rural decen -tralized sewage , a full-scale project design of the combined process of anaerobic /combined process of anaerobic/constructed wetland was introduced .The practical operation result shows that the process has high efficiency and stability , the effluent quality could meet the first level B criteria specified in“Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant” ( GB 18918-2002 ).
