该文研究了长寿城市污水处理厂在平水期和枯水期的尾水排放对三峡水库的水质影响，结果表明，在平水期，水流状态更不利于污染物的输移，使其污染带范围大于枯水期的污染带范围；平水期，TP因人流背景浓度已达到Ⅲ类水质标准，能形成700m的超标（Ⅲ类）污染带，CODMn、NH4-N虽能形成超背景污染带，但不会超出Ⅲ类水质标准；枯水期NH4-N在排污口汇流I断面附近出现了长约50m，宽约50m的超标（Ⅲ类）污染带，CODMn、TP在超背景污染带内的浓度仍满足Ⅲ类水质标准要求。

This paper studied the impact of tail water from Changshou Urban Wastewater Treatment Plant in normal water season and dry season on the water quality of Three Gorges Reservoir. The results showed that the water flow in normal water season was not conducive to the transport of pollutants, leading to a polluted zone wider than in dry season; during normal water season, inflow background concentration for TP reached Class Ⅲ water quality stand- ard, forming a 700 m over-standard （Class Ⅲ ） polluted zone; CODMn and NH4-N might form a polluted zone above its background but not over Class Ⅲ water quality standard; in dry season, NH4-N formed an over-standard （Class Ⅲ） polluted zone 50 m long and 50m wide; CODMn and TP concentrations in the backgrourd polluted zone still met Class Ⅲ water quality standard.
