通吕运河控制断面水质达标分析

文章通过通吕运河规划区域内南通主城区、通州区、海门市、启东市污染物现状入河量和预测量的计算,将通吕运河全线划分为四个水质控制断面,并采用河流一维稳态水质模型对通吕运河沿程水质变化情况进行数值模拟,进行通吕运河四个控制断面水质达标分析,得出选定的四个控制断面水质在不同的污染物入河量时达到地表水环境功能区水质目标需要削减的化学需氧量、氨氮、总磷的排放量,为通吕运河的水环境综合整治提供技术支撑。

Tong Lv Canal Water Quality Control Section Analysis

The calculation of the amount of pollutants into the Tonglv Canal region,the simulation of using river water quality model of the one-dimensional steady-state Tonglv changes in water quality along the canal,the analysis of water quality control section,the COD,NH3-N,TP amount are required to reduce about the selected four control sections obtained at different water quantities of pollutants into the river water quality targets to achieve functional area,in order to pass the canal Tonglv comprehensive improvement of water environment to provide technical support.
