平原地区新建湖库型水源地生态工程设计关键技术问题及实践

Key technologies of the ecology engineering project design for new lake type water source in plain region and their application

平原地区新建湖库型水源地是改善原水水质、保障供水安全的有效工程措施。围绕河道型与湖库型水流、水动力及富营养化差异,分析了工程选址、工程定位及工艺选择中节能、水质协同性及富营养化防治与水质提升等关键问题的影响因素,并以盐城市盐龙湖工程为例进行了相关设计探讨。

Lake type water resource is an effective way to improve the source water quality and secure the water supply. Based on the differences of water flow, hydraulics, and eutrophication be- tween river type reservoir and lake type reservoir, this paper analyzed the influent factors on key points including project location selection, project positioning, coordination between energy saving and water quality in process selection, eutrophication, and water quality improvement. The Yan- long lake project in Yancheng City was used as a case study to discuss related design.
