The study aims to control aquaculture and other runoff non-point pollution sources in an agricul-tural college experimental field.The current study analyzed the pollution sources and developed a compre-hensive technological treatment.The applied strategy includes applying microbial technology,aquatic bio-logical 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 Myrio-phyllum aquaticum,and adding an aeration system,COD,ammonia nitrogen and TP concentration of the fi-nal 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.
