摘　　要：南畬塱排渠流域水系污染较严重,水质大部分属于劣V类,部分水体出现黑臭。本文采用水动力水质软件对河道水质状况进行模拟,建立污染物排放与水质达标的响应关系,主要考虑在水体不黑不臭和水质达到V类水这两种情况下,南畬塱排渠能容纳的最大日负荷量。根据水质现状,选取污染严重的NH3-N作为评价水体黑臭的指标,选取COD、NH3-N作为评价水体达V类水标准的指标,计算得出各对应指标的环境容量,进而提出流域污染削减方案。The water pollution in the drainage basin of nanshelang is serious, and the water quality is basically inferior to class v,part of the water is black and smelly. In this paper, the hydrodynamic water quality software is used to simulate the water quality of the river, and the response relationship between water quality and pollutant discharge is established. The main consideration is the maximum daily load that can be accommodated by the drainage channel of nanshelang when the water is not black or odorous and the water quality reaches class v. The seriously polluted NH3-N is selected as the index to evaluate the black and odorous water body, and the COD and NH3-N are selected as the indexes to evaluate the water body reaching the class V water standard. The environmental capacity of each corresponding index is calculated, and then the pollution reduction scheme of the basin is put forward.
