摘要
武汉市黄陂区处于江汉河湖水网的边缘地带,境内河流湖泊纵横交织,水资源丰富。由于水体承载了过多超自身净化能力的污染负荷,导致区域内水环境不断恶化,这与人民日益增长的对美好生活向往的需求相悖,因此对水环境开展综合治理迫在眉睫。为改善黄陂区某湖水环境,控制入湖污染量,优先对污染最重的A工业园区雨水排口入湖污染现状及成因进行分析,结合现状雨水排口分布及用地条件,提出晴天污水截流及雨天初雨控制的治理对策。为兼顾区域排涝安全及工程经济性,根据武汉市降雨特征,采用InfoWorks ICM对工程实施后雨水系统建模,据此合理确定截流管涵、初雨调蓄及处理设施的规模。通过对工程实施效果进行分析,验证了治理对策的合理性。
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 environment.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 prioritized 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.
