摘　　要：农村生活污水污染问题日益严重,如何根据农村现状选择合适的处理技术显得尤为重要。通过比较上海南汇地区4种已经运行污水处理工艺的效果、管理、投资等,以期为类似地区农村生活污水处理工艺的选择提供参考。结果表明,一体化生物集成工艺可保障废水处理效果,而一体化集成工艺与人工湿地组合工艺则具有很强的耐冲击能力,处理效果稳定;两种方式都可以获得75%以上COD和BOD5去除率,对氨氮去除率超过70%,出水达到上海市污水综合排放标准(DB 31/199-2009)二级标准。农村生活污水治理应因地制宜采用不同的处理工艺,并尽可能集中建污水处理设施以降地建设成本和运行成本。Sewage pollution in rural areas has become increasingly serious,it is very important to choose a suitable technology based on the current status of rural areas.By comparing the effect,management and investment etc.of 4 kinds of sewage treatment process which has been operated in Nanhui District,Shanghai,some references in choice of sewage treatment technology in some rural areas may be given.Results showed that integral biological technology could improve treatment effect,and integral biological technology combining with constructed wetland had good resistance to shock loading,stable treatment effect.The removal efficiencies of COD and BOD5 were more than 75% in both processes,and the removal efficiency of ammonia nitrogen was over 70%,the effluents could meet the second standard issued by Shanghai integrated wastewater discharge standard（DB 31/199-2009）.Sewage treatment technology should be chosen according to the actual local conditions in rural areas,and centralized treatment patter was proposed to reduce the investment and operating cost.
