摘要：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。

Abstract：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 79.96×10`4t/a and 7.56×10`4t/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.

上海市地处长江三角洲前缘,滨江临海,属典型的平原感潮河网地区,城市化水平高,经济社会发达。随着上海经济社会的快速发展和水环境综合治理力度的不断加大,尤其是经过4轮“环保三年行动计划”以及“黑臭河道整治”、“万河整治”的实施,全市水环境质量明显改善。但是,上海市水环境综合治理任重道远,污染源彻底控制还需要一个较长过程,同时受上游省际边界来水变化的影响,全市水环境质量不容乐观,现状水质与水功能区的水质要求还有较大差距,水体使用功能仍受到严重影响,水资源开发利用与保护仍不相协调。上海市作为全国实行最严格水资源管理制度的试点城市之一,迫切需要从严核定纳污能力,建立以限制排污总量为控制核心的水功能区限制纳污制度[1]。……
