南门河水环境容量的确定

Determination of water environment capacity of Nanmen River

在搜集水文水质等参数的基础上,利用"水环境容量分析系统"提供的一维水质模型,对南门河的水质现状进行了评价,并采用正向方法进行了河流水环境容量的计算。结果表明:由于河流本身流量不大,导致在现状排污条件下,水体水质严重超标,必须对该河流进行总量控制。

Based on collected hydrological and water quality data,using one-dimensioual water quality model provided by water environment capacity analysis system,the paper has evaluated the present water quality in Nanmen River.In addition,the water environment capacity of the river was calculated by using forward-computing approach.The result showed that the small flow rate of river has resulted in heavy pollution of watershed.It must be necessary to control the total amount pollutant resource.
