摘要
运用一维水质模型,分别计算出大富水在50%,75%,90%三种保证率最枯月平均流量下的纳污能力,化学需氧量(chemical oxygen demand,COD)为12512.3t/a,8927.8t/a,5898.5t/a;氨氮为614.6t/a,392.1t/a,311.2t/a。根据大富水近年来实际水量和污染情况,采用90%保证率计算得到的纳污能力最为合理,能最大程度地起到限排减排及保护水资源的作用,最后,针对大富水实际情况提出建议。
The one-dimensional water quality model was used to calculate the pollutant capacity of Dafushui at the guarantee rate of 50%, 75% and 90%, The evaluation index values of chemical oxygen demand（COD） were 12512.3 t/a, 8927.8 t/a and 5898.5 t/a; The other evaluation index values of ammonia nitrogen were 614.6 t/a, 392.1 t/aand 311.2 t/a. According to the actual water volume and pollution situation in recent years, the author selected 90% as the most suitable guarantee rate. The pollutant capacity of Dafushui at the guarantee rate of 90% could not only play the role of emission reduction but also protect water resources, which might achieve the best results. Finally, the author put forward some suggestions in view of the actual situation of Dafushui.
