Through the indoor static simulation test on the nitrogen and phosphorus released characteristics of the sediment in Chaohu Lake, the released characteristics of TN and TP in the sediment of Chaohu Lake under different conditions such as different temperatures, different pH values and the disturbance of overlying water and whether the aquatic plants were planted on the sediment were analyzed or not. The results show that, it is beneficial to the release of sediment contaminants with increasing temperature. When pH is neutral, which is not adverse to the release of sediment pollutant, while disturbing overlying water can accelerate the release of pollutant in the sediment, and the effect of eliminating the water body TN is obvious, but the effect of eliminating the water body TP is not obvious.When we plate the aquatic plants, it is good for the release of pollutant in sediment and the improvement of water quality,This can provide a theoretical basis for the control of sediment pollution in Chaohu Lake through the above test.
