摘要:
我国许多历史上水质优良的湖泊水源区已遭污染或严重污染,净化饮用水源刻不容缓.本文介绍了自1991年以来在太湖进行的物理-生态工程(PEE)的部分研究成果.着重介绍在太湖的重富营养湖湾──五里湖无锡中桥自来水厂水源区的静态和抽水动态实验.阐明了PEE净化水质的原理,示范工程结构,若干水生植物生长规律,螺对水的净化作用及工程效果等.PEE能有效地除藻和净化水质.工程对水的浊度、铵氮、亚硝酸氮和色度的降解效果较好,1994年8月-1995年6月间工程输出水比工程外原水分别平均削减82%,60%,69%和46%.

Abstract:
Water quality was very good in many middle-large scale lakes and urben lakes in China before 1970s. These lakes were selected as the raw water sources for advanced treatment of drinking water and/or recreation lakes. But the eutrophication process developed rapidly and the water quality in more and more lakes is lower than the standard for drinking and recreation recently. Purifying raw water quality in lakes is an urgent problem faced in many regions for sustainable development. Some Physico-Ecological Engineering (PEE) experiments in Taihu Lake have been doing since 1991. The research results were summarized partly in this paper, including the principles for purifying water quality, the construction of the model engineering, the growth laws of some species of floating plants, the roles and effects of snail (Bellarnya aeruginosa) in purifying water quality, and the efficiency of PEE. The experiment took place in the hypertrophic bay of Taihu Lake -Wulihu Lake, in the intake area of Wuxi Zhongqiao Drinking Water Supply Plant (ZDWSP), with an experiment area of 2200m2 and depth of about 1.6m. The static and dynamic pumping experiments have been doing since August 1994. The PEE may effectively remove algae and purify water quality. The mean reducing rates of PEE for turbidity, NH4+-N, NO2+-N, and colour are 82%, 69%, 69%, 46% respectively during August 1994-June 1995.
