In order to study the dehydration and solidification with consolidation agent on the lake bottom mud dredging in application quantitafively,to random sampling the constituent parts of silt cake and the water quality of filtration after treatment is carried out;and long-term fixed-point monitoring the lake water quality in the water of Moshui Lake restoration project.And the purpose is achieved by analyzing the monitoring data.After the examination,the various indices of silt cake and filtration both are up to the relevant standard for the comprehensive treatment of mud environment of the lake.It is indicated that the disposal of silt cake and the discharge of filtration will not cause damage and pollution to the environment.And there are dramatic decline in the water quality indices such as TP,TN and COD with long-term monitoring of the water quality of the lake.It is indicated that the technology can improve the lake's water quality.
