初雨截留系统在河道水环境综合整治工程中的应用分析——以深圳某河道水环境综合整治工程为例

Application Analysis of Initial Rain Interception System in River Water Environment Comprehensive Improvement Project--Taking a River Water Environment Comprehensive Improvement Project in Shenzhen as an Example

以深圳某河道水环境综合整治工程为例,引入初雨的概念,并重点介绍了初雨截留系统在河道综合整治工程中的应用,通过对某河道初雨系统实施前后不同桩号取样,重点监测了下雨后河道氨氮、溶解氧、氧化还原电位等水质指标的变化,通过数据分析,验证初雨截留系统对河道水质的提升效果,以及论证了部分地区对于水质要求较高的河道建设初雨截留系统的必要性,为其他河道水环境综合整治工程提供技术参考。

Taking the comprehensive improvement project of water environment of a river in Shenzhen as an example,the concept of initial rain and the application of initial rain interception system in the comprehensive improvement project of the river are mainly introduced.Through the sampling of different pile numbers before and after the implementation of the initial rain system of a river,the changes of water quality indexes such as ammonia nitrogen,dissolved oxygen and redox potential after rain are monitored.Through data analysis,the effect of the initial rain interception system on the improvement of river water quality is verified,and the necessity of constructing the initial rain interception system in some rivers with high water quality requirements is demonstrated.Technical reference is provided for other river water environment comprehensive improvement projects.
