湖水生态修复与水质改善方法设计

Design of Ecological Restoration and Water Quality Improvement Methods for Lake

湖水生态修复与水质改善具有重要现实意义。本研究以南湖水质改善项目为例,以2017年水质监测数据为依据分析了项目改造以前的水质情况,发现南湖水质处于Ⅴ类和劣Ⅴ类之间,水体主要超标因子为总磷,水体处于轻度、中度富营养状态。并从污水截流与水体连通、湖泊水质修复工程、水位调控、重点区域强化净化以及湖泊生态基质修复等方面介绍了南湖水质改善项目的具体措施,以期为其他湖水生态修复与水质改善工程提供一定借鉴。

The ecological restoration and water quality improvement of lake water have important practical significance.This study takes the Nanhu water quality improvement project as an example and analyzes the water quality situation before the project renovation based on water quality monitoring data in 2017.It is found that the water quality of Nanhu is between Class V and inferior to Class V.The main exceeding factor of the water body is total phosphorus,and the water body is in a mild to moderate eutrophication state.And specific measures for the Nanhu water quality improvement project were introduced from aspects such as sewage interception and water body connectivity,lake water quality restoration engineering,water level regulation,strengthening purification in key areas,and lake ecological matrix restoration,in order to provide a reference for other lake ecological restoration and water quality improvement projects.
