In view of the problem of endogenous pollution in Baiyangdian，we carry out experimental research on Baiyangdian water environmental treatment. Ecological dredging is used as the main plan to implement different ecological desilting measures by adopting the environmentally friendly cutter suction boats，mud pumps and dry excavation for different underlying surface types，supplemented by reasonable sediment transportation，dewatering，mud resources and residual water treatment. After implementation of the project，the expected experimental research results are achieved，which provides a strong support for the formation of a feasible and effective Baiyangdian water environmental treatment model.
