摘　　要：针对农村分散点源生活污水覆盖面广、分散性强、水质水量不均衡、收集处理率低等特点,通过电解-MBBR一体化反应器处理实际村镇分散生活污水。分阶段调整运行条件,重点检测工艺对COD、氨氮、TP的去除效果并分析原因,验证一体化反应器运行效果。结果表明:对COD、氨氮和TP的去除率分别为91.74%、98.32%、90.80%,出水水质达到《城镇污水治理厂污染物排放标准》(GB 18918—2002)一级A标准,为村镇分散点源污水治理提供参考。With the progress of rural construction and the improvement of residents'living standards,the collection and treatment of domestic sewage in rural areas need to be solved.Rural domestic sewage has the characteristics of wide coverage,strong dispersion,uneven water quality and quantity.The electrolysis-improved MBBR process and integrated equipment were used to treat the scattered domestic sewage in villages and towns.The operation conditions were adjusted in stages.The removal effects of COD,NH3-N and TP by the electrolysis-improved MBBR process were mainly detected,and the reasons were analyzed to verify the operation effect of the integrated equipment.The removal rates of COD,NH3-N and TP were 91.74%,98.32%and 90.80%,respectively.The effluent met the first A class standards specified in GB18918—2002 Discharge standard of urban sewage.The paper can provide some reference for decentralized treatment of rural domestic sewage.
