基于两种不同计算模型的丹河水环境容量分析

以水环境功能区区划为基础,进行了丹河流城水系特征、水文特征和入河污染源现状调查,在此基础上,对丹河流域各排污口的排放量及污染物进行分析,以流域各功能区应达到的水质目标和恢复其应有的自然功能为依据,建立一维稳态条件下水环境容量计算两种的模型:完全混合水环境容量模型解析解和非线性衰减、多点容量计算模型,计算出流城内水环境容量.以此为依据可对排入丹河污染物的量进行控制,为总量控制提供了较适用的方法.

An Analysis of Water Environmental Capacity Based on Two Calculation Models in Dan River Valley

The discharging pollutant sources and pollutants of Dan river valley were analyzed,in order to maintenance the water equality goal of each environment function functional zoning or to revivify the river's natural function,two calculation models of water environment ca- pacity were putted forward in case d one dimension,the complete mixture model d water environment capacity and the non-linearity attenu- ation multi-spot model d water environment capacity.The allowable water environment capacity was calculated with the two models.So the quantities of pollutants discharging into Dan River valley could be controlled and it was helpful to total pollutant control.
