摘要
城市河道水环境治理需要有系统思路并采取综合治理措施,本文论述了普陀区外浜水系水环境治理的过程,对技术路线和治理方案进行了阐述,对治理效果进行了对比总结,特别是对于工程中运用到的3项新技术进行了详细说明。结果表明:普陀外浜水系中的4条主要河道经过治理后,氨氮和总磷等主要指标均明显下降,河道透明度大幅提升,低维护长效稳定的水生态系统逐步形成。研究成果为类似城市河道水环境治理提供了较好的借鉴和参考。
The water environment treatment of urban rivers needs systematic thinking and comprehensive treatment measures.This paper discusses the process of water environment treatment in peripheral river system of Putuo District,expounds the technical route and treatment scheme,compares and summarizes the treatment effects,and especially explains in detail the three new technologies applied in the project.The results show that after the treatment of the four main rivers in Putuo peripheral river system,the main indexes such as ammonia nitrogen and total phosphorus are obviously decreased,the transparency of the rivers is greatly improved,and the low-maintenance,long-term and stable aquatic ecosystem is gradually formed.It provides a good reference for river water environment treatment in similar cities.
