摘要：

河流水环境容量是实行污染物排放总量控制的理论依据，也是河流水环境管理的科学基础。本文采用综合标识指数法识别河流水质污染状况及主要污染指标，对寇河水系水生态功能分区进行水质评价，水生态功能分区是基于对流域水生态系统的区域差异的研究而提出的一种分区方法；采用一维稳态水质模型模拟河流水质变化规律，并结合线性规划模型，计算寇河上游水生态较高功能区、寇河中游水生态较低功能区、南城子水生态较高功能区的CODCr和NH4-N的水环境容量。结果表明：寇河上游水生态较高功能区CODCr和NH4-N的水环境容量分别为852.22  t·a-1、47.96  t·a-1；寇河中游水生态较低功能区CODCr和NH4-N的水环境容量分别为410.33  t·a-1、23.09  t·a-1；南城子水生态较高功能区CODCr和NH4-N的水环境容量分别为25.23  t·a-1、1.58  t·a-1。

Abstract:

The river water environmental capacity is a theoretical basis for the implementation of total quantity control on pollutant emission, and it is also a scientific basis for river water environmental management. Using a comprehensive identification index method, water pollution situation of the river and the main pollution indicators were identified, and water quality of different aquatic ecological function regionalizations in the Kou River was assessed. The method on aquatic ecological function regionalization was put forward based on the difference of water ecological system. The variation of river water quality was simulated by a one-dimensional water quality model, and water environmental capacity of CODCr and NH4-N in the Kou River upstream higher aquatic ecological function regionalization, the midstream lower aquatic ecological function regionalization, Nanchengzi higher aquatic ecological function regionalization were calculated combining with a linear programming model. The results show that water environmental capacity of CODCr and NH4-N are 852.22 t·a-1 and 47.96 t·a-1 in the Kou River upstream higher aquatic ecological function regionalization, 410.33 t·a-1 and 23.09 t·a-1 in the Kou River midstream lower aquatic ecological function regionalization, 25.23 t·a-1 and 1.58 t·a-1 in the Nanchengzi higher aquatic ecological function regionalization, respectively.
