Historical Review and Water Environment Improvement Project Planning of Shahu Lake in Wuhan

Shahu Lake; water environment treatment; pollution sources quantification; project planning; long-term management

With the development of urban, there was some problems of urban lake pollution in Wuhan which is famous for the large number of lakes. Taking the inner lake of Wuhan —Shahu Lake as an example ， its historical situation and pollution control process were reviewed， and its current situation was investigated, analyzed and evaluated. Then, the corresponding measures including the improvement of the peripheral wastewater treatment system ， the control of outside source pollution， the control of sediment， vegetation recovery and other aspects were proposed ．To ensure that the level of management could be maintained in a good degree for a long time, a long-term management scheme combining automatic monitoring, remote scheduling, multi-party cooperation and hydraulic dispatching was proposed based on the existing engineering schemes. The water body treatment and ecological restoration mode of the project could provide reference for the treatment of other similar lakes.
