模拟不同抽排水方式对封闭性水域环境净化效应的研究

The Purification Effects on Closed Water Area by Different Simulating Methods of Water Pumping and Drainage

针对封闭性水域内水流交换能力低下，易产生富营养化的特点，采用生态模型，对水域内设置抽排水和水质处理设施等情况下水域环境的净化效果，用数值模拟方法进行了探讨。模拟结果表明，湾凹抽水、湾口排水的布置方案，可有效地改善水域环境，防止富营养化产生。

With an aim at lower capacity of water flow exchange in a closed water area characterized by easy occurrence of eutrophication, the mathematical simulation method is used to study the purification effects on water area in different cases of installing water pumping and drainage facitilities and water quality disposal devices in a water area by adopting the bioecological models. The simulating results indicate that this layout scheme of pumping water in narrow area of gulf and draining water in the open of gulf can improve water area environment and prevent the occurrence of eutrophication effectively.
