摘　　要：浙江省于2003年通过全面推进“千村示范、万村整治”工程和美丽乡村建设,不断加大农村环境综合整治力度,有效改善了农民的生产生活条件。目前,浙江省污水处理终端运行最长时间高达5年,以浙江省某县681个农村生活污水处理终端为研究对象,统计分析1年内各终端运行效果、出水水质。结果显示,研究区域内,终端出水平均达标率为87.7%;导致终端出水水质不达标的污染物指标主要为氨氮、总磷,其占比分别为34%、27%;在人工湿地、PKA湿地、微动力、自然湿地4种工艺中,PKA湿地处理效果最佳,人工湿地、微动力、自然湿地处理效果相差不大。研究结果可为农村生活污水处理工艺的选择、运行维护提供参考借鉴。In 2003,Zhejiang Province continuously strengthened the comprehensive improvement of rural environment by comprehensively promoting the project of“demonstration of thousands of villages and renovation of thousands of villages”,and the construction of beautiful villages,effectively improved the production and living conditions of farmers.At present,the longest operation time of the terminal in Zhejiang Province is as long as 5 years.Taking 681 rural domestic sewage treatment terminals in a county of Zhejiang Province as the research object,the operation effect and effluent quality of each terminal in one year are statistically analyzed.The results show that in the study area,the average rate of terminal effluent is 87.7%.The effluent from the sewage treatment terminal that does not reach the standard because of the main pollutants NH 3-N and TP accounted for 34%and 27%respectively.Among the four processes of constructed wetland、PKA constructed wetland、micro power and natural wetland,the treatment effect of PKA wetland is the best,and there is little difference between constructed wetland,micro-power wetland and natural wetland.The results of this study can provide reference for the selection,operation and maintenance of rural domestic sewage treatment process.
