摘　　要：为治理某农业院校试验田地表径流和水产养殖等面源污染,结合已有面源污染防治技术和水体污染综合治理思路,分析了污染源并制定了综合治理技术方案,应用微生物技术、水生生物系统、曝气技术等技术手段,辅助科学的纳污引水连通及排水工程进行综合治理实证研究,目标是末端排放口水体水质稳定达到地表水Ⅳ类水水质标准。结果表明:通过实施投加微生物菌种、种植挺水植物、种植沉水植物、设立生态浮岛、种植粉绿狐尾藻、增设曝气系统等措施,末端排放口水体中COD、氨氮和TP浓度从治理前的22.10、2.76、0.124mg/L降至治理后的12.02、1.27、0.098mg/L,达到了地表水Ⅳ类水水质标准。The study aims to control aquaculture and other runoff non-point pollution sources in an agricultural college experimental field.The current study analyzed the pollution sources and developed a comprehensive technological treatment.The applied strategy includes applying microbial technology,aquatic biological systems,aeriation technology and other technical means.The study introduced scientific pollution diversandard.The results are as follows:through the implementation of measures such as microbial strain addition,water-lifting plant planting,submerged plant planting,ecological floating island,planting Myriophyllum aquaticum,and adding an aeration system,COD,ammonia nitrogen and TP concentration of the final drainage port decrease from 22.10,2.76,0.124 mg/L at the beginning of treatment to 12.02,1.27,0.098 mg/L after treatment,which meets the discharge requirements.
