Impacts of aeration on transport and transformation of pollutants between the sediments and overlying water in the tributary of Dianchi Lake was researched by simulated experiments. Results showed as following: (1)Aeration caused pH value of overlying water increased; (2) Total nitrogen(TN) and Total phosphorus(TP) in overlying water presented similar decreasing trends in the case of continuous aeration., and the average variation rate of TN and TP were -0.156 mg·L^-1·d^-1 , -0.060 mg·L^-1·d^-1. But for the non-aeration condition, ...
