上海市水功能区纳污能力和分阶段限排总量研究

Study on pollutant carrying capacity of water function zone in Shanghai City and its total pollutant discharge limits of different stages

以COD、NH3-N为控制指标,应用一维感潮河网纳污能力模型计算上海市水功能区水域纳污能力。结果表明,上海市水功能区COD和NH3-N的纳污能力分别为79.96万t/a和7.56万t/a。以水功能区水质和污染物入河量分析评价结果为基础,制定水功能区分阶段达标目标,并从空间和时间上分解,提出每个水功能区分阶段限制排污总量控制方案。

Taking COD and NH3-N as the control index,the pollutant carrying capacity of water function zone in Shanghai were calculated by using the one dimensional tidal river network pollutant carrying capacity model. The results show that the pollutant carrying capacity of COD and NH3-N in the water function zone of Shanghai is 79. 96×104t / a and 7. 56 ×104t / a,respectively. Based on the analysis of the water quality and the pollutant discharged in water function zone,the phase goals of water function zone were set up with the goals decomposed from time and space,and the control scheme of the total pollutant discharge limits in different stages of every water function zones were put forward.
