Pollution Analysis and Control Countermeasures Research of the Key Area of a Lake in Huangpi District,Wuhan City
Huangpi District of Wuhan City is located at the edge of the Jianghan water network,where rivers and lakes are intertwining vertically and horizontally with sufficient water resources.Due to the excessive pollution load that exceeds their own purification capacity,the water environment continues to deteriorate,which is contradictory to people's growing demand for a better life.Therefore,it is extremely urgent to comprehensively treat the water en-vironment.In order to improve the water environment of a certain lake in Huangpi District and control the pollution entering the lake,the present pollution status and clauses of the most polluted area,A industrial park,was priori-tized from the rainwater discharge outlets into the lake.Based on the current distribution of stormwater outlets and land use conditions,the management countermeasures for intercepting sewage during sunny days and controlling the initial rainwater runoff during rainy days were proposed.In order to balance regional flood control safety and project economy,according to the characteristics of rainfall in Wuhan City,the InfoWorks ICM model was used to model the stormwater system after project implementation and determine scale of interception pipe culverts,initial rain regulation & storage,and treatment facilities.The rationality of the management strategies is verified by the analysis of project implementation.
