基于耦合模型的河网湖泊污染物输移扩散效果分析

Analysis of Pollutant Transport&Diffusion Effect in Rivers&Lakes Based on Coupling Model

针对补水循环及水系贯通工程2种水环境治理工程中常用手段,以老港基地水系为例,基于一、二维耦合的水动力及水质模型,对其治理效果进行研究。研究表明:补水循环和水系贯通工程对于改善区域水环境状况非常有效,可促使水系内水流单一方向流动的工程方案治理效果较好,贯通断头河道可改善水系局部水动力条件。研究结果可为工程规划提供依据,也为类似工程提供借鉴。

Aiming at the two common means of water environment treatment engineering:water replenishment cycle&water system connection engineering,taking the water system of Laogang base as an example,the treatment effect is studied based on 1D&2D coupled hydrodynamic&water quality models.The research shows that the water replenishment cycle&water system connection project are very effective to improve the regional water environment,and the engineering scheme that can promote the flow in a single direction in the water system has a good treatment effect.Connecting the broken river channel can improve the local hydrodynamic conditions of the water system.The research results can provide basis for engineering planning&reference for similar projects.
