【摘要】 湖泊富营养化是重大水环境污染问题,目前我国正在开展富营养化的研究及其综合治理。本文分析了底泥疏浚工程、生态引水工程和水生植物修复三种典型的内陆湖泊内源污染治理工程技术在治理湖泊富营养化过程中的作用,综述了三种工程措施在国内外的运用现状,比较了三种措施在改善湖泊水环境过程中的优点和不足,指出在解决湖泊富营养化问题时单独使用其中一种方法都存在的局限性,在此基础上,以滇池为例,对三种工程措施的治理效果和结合途径进行探讨。更多还原

【Abstract】 Lake eutrophication is a serious environmental problem.China is carrying out research on eutrophication and its comprehensive treatment at present.The effects of three typical inland lake internal source pollution treatment projects,such as sediment dredging engineering,ecological diversion project and aquatic phytoremediation,were analyzed in this paper.The operating status of these three methods both at home and abroad,and their merits and demerits in treating lake pollution were illustrated.Simultaneously,the authors pointed out that there are limitations when one kind of method is used alone in solving the problem of eutrophication.On this basis,taking the water quality control project of the Dianchi Lake for example,the treatment effect and the combined use of the three engineering projects were investigated.更多还原
