水利水电工程设计

针对城市河道雨水排口污染问题，提出一种生态景观式净化系统的构建体系。该系统结合生态功能和景观美学，通过布置由堆石消能段、生态沉砂池、生态旱溪、生态植物塘组合形成的多级净化单元的设计，能有效去除雨水径流中的污染物，同时具有良好的景观效果。本研究为城市河道雨水排口治理提供了新的思路和技术支持，对改善城市水环境质量具有重要意义。

This article proposes a construction system for an ecological landscape based purification system to address the pollution problem of rainwater discharge outlets in urban rivers. This system combines ecological functions and landscape aesthetics, and is designed with multi-level purification units composed of stone energy dissipation sections, ecological sedimentation tanks,ecological dry streams,and ecological plant ponds. It can effectively remove pollutants from rainwater runoff and has a good landscape effect. This study provides new ideas and technical support for the management of urban river rainwater discharge outlets,which is of great significance for improving the quality of urban water environment.
