【摘要】 优化配置入河污染物即是将水环境容量作为一种自然资源进行分配,是缓解和解决河流水污染问题的有效方法之一。河流修建大量闸坝致使河道水流状况发生显著变化,传统的方法无法计算闸坝河流的水环境容量。以辽宁太子河为例,根据当地的自然地理条件及水利工程状况,模拟水体自净能力和污染物迁移转化规律,结合现状排放量以污染物排放总削减量最小为目标,优化配置各河段水体的污染物排放量及污染物削减量,计算闸坝河水段质的达水标环。境容量。经过优化配置后各排污口CODCr排放量总和较现状排放量有所减少,并保证各个水质控制断面更多还原

【Abstract】 Optimization allocation for quantity of pollutant discharged means treating water environmental capacity as a kind of natural resource for distribution.It is an effective method for relieving and solving water pollution problems.Traditional method can’t calculate the water environmental capacity of river with dam,when dam construction in river causes the significant change in flow.Take Taizi River as an example,based on local physical geographical conditions and hydraulic engineering layout,the author simulated the self purification of water bodies and the movement and transformation discipline of contamination.By combining present quantity of pollutant discharged,and minimizing the total amount of reduction,we can get the specific values of pollutant discharged and amount of reduction in different districts,and calculate the water environmental capacity of different reaches.Total emission in all outlets has been reduced under optimization allocation,with each water quality control section up to standard.更多还原
