摘要

[目的] 对太湖流域河网水体生态修复工程及其效果进行对比分析

为该流域环境管理及水质改善提供基础。[方法] 以太湖流域的夏庄浜、洛西河、凤沟河三条河流为例

通过在河道中分别实施复合塔式生物滤池处理工艺、五级负荷削减治理工艺、生态景观修复工艺

对3个工程的运行效果进行比较

研究出适用于流域河网地区的生态修复技术。[结果] 三条河流生态修复工程的处理效果由强到弱依次为:夏庄浜 >洛西河 >凤沟河

由此可得3种生态修复工艺的去除污染物能力顺序为:复合塔式生物滤池处理工艺 >五级负荷削减治理工艺 >生态景观修复工艺。[结论] 污染物去除效果表明

3种工艺对河道中氮、磷等污染物质的去除效果均较好

并具有良好的生态景观效果

通过进一步优化

可形成适用于河网地区的水质改善关键技术。

Abstract

[Objective] The ecological restoration project for the river network of Taihu Lake basin and its effects were analyzed and compared in order to provid some bases for the environmental management and water quality improvement of the catchment.[Methods] Xiazhuang River

Luoxi River

Fenggou River of Taihu Lake basin were selected to carry out three projects as composite tower bio-filter treatment process

five-levels-load reduction treatment process and ecological landscape restoration process

respectively. After three rivers' operation

the effects of these three demonstration projects were compared.[Results] The three ecological restoration projects had a effectiveness rank of Xiazhuang River >Luoxi River >Fenggou River. Thus

the ability of remove pollutants of the three ecological restoration processes ranked as:composite tower bio-filter treatment process >five-levels-load reduction treatment process >ecological landscape restoration process.[Conclusion] The three technologies can all effectively remove nitrogen

phosphorus and other pollutants of watercourse; They also have good ecological landscape. Considered the room of design and use optimization in river network

they could formed the key technologies of water quality improvement for river network.
