水库纳污能力计算是纳污总量控制和水库水环境管理的基本依据。分别运用均匀混合模型、狄龙模型动态计算了不同频率下渔洞水库中CODMn、NH3-N、TN和TP四种污染物的月纳污能力,并将月纳污能力和月污染物入库量进行逐月比较,获得了超标排放时所需削减污染物的量。结果表明,NH3-N、CODMn不是渔洞水库主要污染因子,暂不需要对污染物排放量进行削减;TP在个别月份需要对排放量进行削减;TN的污染形势异常严峻,是渔洞水库最重要的污染因子,几乎全年需要对排放量进行削减。针对水体污染情况,提出了控制渔洞水库面源污染的措施建议。
Calculation of storage capacity of a reservoir is the basic basis for total pollutant discharge control and reservoir water environment management. Using the uniform mixing model, the Dillon model dynamically calculates the monthly pollutant holding capacity of four pollutants CODMn, NH3-N, TN and TP in the Yudong Reservoir at different frequencies. The monthly pollutant insolation capacity and monthly pollutant storage amount Monthly comparisons gave the amount of pollutants that would have been required to reduce emissions when they exceeded the standard. The results show that NH3-N and CODMn are not the main pollution factors of Yudong Reservoir, and the emission of pollutants need not be reduced at present; TP needs to reduce the emission in a few months; the pollution situation of TN is extremely severe, Important pollution factors require reductions in emissions almost the entire year. In view of the pollution of water bodies, some measures to control non-point source pollution in Yudong reservoir are proposed.
