摘要
水体纳污能力的计算是河流污染物总量控制及水环境管理的基本依据。在统计湘江流域污染物排放量的基础上,选用一维河流水环境数学模型,按照流域内各水功能区水质目标要求,计算得出湘江会昌流域段水体纳污能力,并与现状污染物排放量进行了对比。结果表明:湘江会昌段CODcr、NH3-N、TP纳污能力分别为6 862.83,1 559.96,208.31 t/a,湘水会昌工业用水区CODcr、NH3-N削减量分别为239.67,90.07 t/a,削减率分别为25.12%,50.75%;湘水寻乌-会昌保留区TP削减量为72.51 t/a,削减率为29.5%。
The pollution bearing capacity calculation of water bodies is the basis for the total pollutant control and environmental management of rivers. On the basis of counting the pollutant discharge amount in Xiangjiang River Basin and referring the water quality control goal of water function zones,the bearing capacity of Huichang reach of Xiangjiang River was calculated with one dimensional river environmental mathematical model and the results were compared with current pollutant discharge. The calculation results show that the bearing capacities of CODcr,NH3- N,TP of Huichang reach are 6862. 83,1559. 96,208. 31 t / a,the reductions of CODcr、NH3- N in Huichang industrial water zone are 239. 667,90. 07 t / a with reduction rate of 25. 12%,50. 75%. The reduction of TP in Xunwu- Huichang water conservation zone is 72. 51 t / a with reduction rate of 29. 5%.
