摘要/Abstract

摘要： 复杂河湖系统的总量控制需考虑河湖双重控制目标,以太湖西北部竺山湾流域为研究对象,运用排污系数法计算了区域内的入河污染负荷;构建了一维河网和二维湖体水环境数学模型,对水环境数学模型进行了率定;基于多重目标的河网水环境容量计算方法,计算了河网水环境容量,并分配至各控制单元;定量分析了各控制单元各污染物总量达标情况下的削减量及削减率。结果表明:竺山湾流域COD削减量为834.4 t,削减率为13.8%;氨氮削减量为226.1 t,削减率为36.5%;总氮削减量为724.8 t,削减率为55.2%;总磷削减量为108.9 t,削减率为73.4%。论文成果对于开展竺山湾流域污染物总量控制和水环境保护具有重要指导意义,同时为类似的河湖系统水污染物总量控制提供借鉴。

Abstract: Total amount control for a complicated river-lake system should consider water quality objective of rivers and lakes simultaneously. Zhushan Bay watershed to the northwest of Lake Taihu was selected as the research area. Pollution loads discharged into rivers were estimated by the discharge coefficient approaches. Water environmental models for the One-dimensional river network and two-dimensional lake were constructed and calibrated. Water environmental capacity of river network was calculated based on the calculation method of multi-objectives, and assigned to each control unit. The reduction amount and reduction rate under the condition of total amount of each control unit reach water quality standards were quantitatively analyzed. The results showed that the reduction amount of COD, NH₃-N, TN and TP is 834.4 tons, 226.1 tons, 724.8 tons and 108.9 tons, respectively, and the reduction rate is 13.8%, 36.5%, 55.2% and 73.4%, respectively. This paper played a guiding role for total amount control and water environmental protection in the study area, and more importantly, provided important reference for total amount control in a complicated river-lake system.
