太湖流域产业、人口集聚,水环境污染已经成为整个太湖流域经济可持续发展的制约因素之一,为解决经济发展引起的环境问题,对污染物排放实行总量控制至关重要.为此以太湖流域梅梁湾、竺山湾上游集水区域(重污染区)为研究区域,全面调查区域社会经济、产业结构、土地利用以及各类污染源现状,构建重污染区套网格水文、水质数学模型,计算区域水环境容量与污染物削减量,依据水功能区划与水域面积分配到各镇(街道),确定重污染区以镇(街道)级为基本单位的分阶段总量控制目标,制订主要污染物控制与负荷削减综合系统方案,提出2015年各类污染源重点工程措施,方案实施后区域河网水质平均达标率达80%,为太湖流域水环境管理提供技术支撑.
As industry and population increase rapidly,the pollution of water environment has become a main factor influencing the sustainability of economic development in Taihu Basin.In order to achieve the integrated development in economy and environment protection,the implementation of total quantity control of pollutant discharge is important.In the study areas of Meiliang Bay and Zhushan Bay,we made a comprehensive research on situations of area economy,industrial structure,landuse and status of pollutant sources.Nested grid hydrology model and water quality model have been established to calculate regional water environmental capacity and pollutant reduction.Based on the water function and water areas,the water environmental capacity was assigned to every town(settlement).Thus the aim of total quantity control in different periods of each town and the plan of control and reduction of main pollutants have been established.The solution of pollutant control of each source in different periods has been proposed.Qualifying rate of regional water quality in river network areas will reach 80% by the year of 2015 after the plan implemented.The plan will provide technical support for the water environmental management of Taihu Basin.
