宋公河人工湿地设计方案优化探讨

Study on Optimization of Design of Constructed Wetlands in Songgong River

人工湿地是宋公河综合整治工程的重要组成部分,对整体治理方案进行了介绍,重点针对原湿地设计方案存在的水质处理达标难度大、场地景观效果不佳、工程造价高等问题,提出了减小场地填方、优化工艺流程、对湿地单元进行艺术化改造和梯级布置、优化渡槽走向和铺设形式、优化拦水坝形式等措施,对工程进行整体艺术构思和景观设计,最终将湿地打造为工艺功能与景观功能并重的湿地公园,为山地条件下水处理型人工湿地的构建提供了案例借鉴。

Constructed wetlands ( CWs) were the important parts of the comprehensive improvement project of Songgong River. The original CWs design had some disadvantages such as low treatment efficiency, poor landscape function and high project cost. So the corresponding design was revised. In this paper, the revised contents included reducing site fill, optimizing process flow, layout and some facilities ( aqueduct and dam). In addition, the landscape design was also considered and the combined CWs had been built into the wetland park, which could give some suggestions for the similar cases in mountainous regions.
