摘　　要：农业面源污染是指在农业生产活动中,氮素和磷素等营养物质以及其它有机污染物、无机污染物、土壤颗粒等沉积物,通过农田的地表径流和地下渗漏造成水域环境的污染。由于涉及范围广、控制难度大,农业面源污染已成为影响水体环境质量的重要污染源。对于农业面源污染的调控治理,目前在国内还没有一套定型的方案。人工湿地由于其投资省、运行维护方便、处理效果好，The effects of agricultural non-point source pollution control by pond-wetland combined system in Shenxi river basin of Anji county were studied based on nearly one-year＇s experiment.The removal rate of total nitrogen（TN）,total phosphorus（TP） and chemical oxygen demand（COD） of the pond-wetland combined system was also studied with different inlet wastewater concentration and time.The results showed that the removal effect of TN,TP,and COD in pond-wetland combined system was fairly good.The removal rate of TN,TP,and COD in the system could respectively reach 96%,98%,82% when the TN,TP,and COD of inlet wastewater reach the highest point 33.3,0.99,and 121.6 mg·L^-1.Generally,the removal effect of the system was better in plant growth season and higher concentration of inlet wastewater period.
