|
摘要
介绍了厦门市海沧区新阳主排洪渠基本情况和水环境现状,分析了新阳主排洪渠污染治理面临的主要问题。结合流域污染控制方案,提出了新阳主排洪渠生态修复工程的设计思路、主要目标和生态修复工程方案:在内源清理、源头面源污染控制和污水有效截留的基础上,制定了改造入渠排水口,设置渠道水生态循环处理台地,增加必要的人工推流曝气设施等综合处理方案。经过一定时间的调试运行,目前水质有明显改善,已基本消除黑臭,为河道水系修复和治理提供了新思路。
The basic situation and water environment of Xinyang main flood drainage channel in Haicang District of Xiamen City is introduced,and the main problems faced by pollution control of Xinyang main flood drainage channel is analyzed.Combining with the pollution control scheme of the river basin,the design idea,main objectives and ecological restoration project scheme of Xinyang main flood drainage channel are put forward.On the basis of non-point source pollution control at the source and effective interception of sewage,comprehensive treatment schemes such as reforming the intake and drainage outlet,setting up ecological recycling treatment wetland for channel water,and adding necessary artificial push-flow aeration facilities are put forward.After a certain period of debugging and operation,the water quality of the main flood drainage channel in Xinyang has been significantly improved,and the black odor has been basically eliminated.While improving the water environment,the landscape function of both sides of the channel has been upgraded to increase peoples sense of happiness and acquisition,which provides a new idea for river system restoration and management.
