【摘要】：为实现浑太河流域经济社会可持续发展、排污口排污权最大程度优化、工业及农业合理布局,通过区域水环境容量优化配置,分区段对浑河上游主要排污口、太子河流域生活排污口的交易情况进行优化计算,采用"排污口(直排口)—子流域(支流)—流域/干流"的分配过程对陆域、入河排污口、污染源的水环境容量总量进行分配。结果表明:(1)在考虑安全余量的情况下,对流域COD、氨氮水环境容量总量进行初次分配,分配总量分别为141 343 t、13 636 t,削减量分别占污染物应削减量的44.4%、47.7%,污染物治理总投入为2.18亿元,基本上能够实现流域污染物削减50%的控制目标。(2)通过加大污水处理厂建设力度以及污水达标处理力度进行二次削减,COD、氨氮排放总量分别为208 832 t、17 177 t,分别是流域水环境容量的1.48倍、1.26倍。(3)借助流域水量调整和下泄方式转变对流域污染物最大允许排放情况进行优化控制,得到COD、氨氮的最大允许排放量分别为158 313 t、14 796 t。重新分配后的水环境容量能够保证污染物入河后的水体浓度达标。
[Abstract]:In order to realize the sustainable development of economy and society in Hun Tai River Basin, optimize the sewage discharge right of sewage outlet to the maximum extent, optimize the layout of industry and agriculture, and optimize the water environment capacity of the region, the main sewage outlet in the upper reaches of the Hunhe River can be divided into sections. The transaction situation of domestic sewage outlet in Taizi River Basin is optimized and the distribution process of "sewage outlet (direct outlet / sub-basin) (tributary / main stream)" is used to distribute the land area and the river discharge outlet. The results show that the total environmental capacity of COD, ammonia and nitrogen in the watershed is initially allocated with the consideration of the safety allowance. The total amount of distribution was 141,343 t / t ~ 13,636 t, respectively, and the reduction amount was 44.4% of the total amount of pollutants to be reduced, and the total investment for pollutant control was 218 million yuan. Basically, the control target of 50% reduction of pollutants in the basin can be achieved.) by increasing the construction of sewage treatment plant and the treatment of wastewater up to standard, the total amount of ammonia nitrogen discharge is 208,832 t / t 17 177 t, respectively. The maximum allowable discharge of pollutants in the basin is controlled optimally with the help of water volume adjustment and drainage mode change of water environment capacity of 1.48 times and 1.26 times of water environment capacity. The maximum allowable discharge of ammonia nitrogen was 158,313 t ~ (14 796) t, respectively. The water environmental capacity after redistribution could ensure the concentration of pollutants to reach the standard after entering the river.
