湖泊富营养化的生态修复研究进展

近年来.随着人口增长和经济的迅速发展.以及对水资源的不合理开发利用,使水域环境富营养化呈现加剧恶化的趋势,鉴于传统物理、化学方法所带来的难操作、成本高、易产生二次污染等问题,人们越来越多的将目光转向利用人工湿地、生态浮床、生物操纵等生态修复技术的研究中.这类技术通过植物、动物、微生物间的协同作用,达到净化水质的目的,同时可获得一定的经济效益和社会效益。本文综述了人工湿地技术、生态浮床技术、生物操纵技术的研究现状.讨论了各项技术的不足之处,提出需根据不同湖泊的特性,利用模型研究确定不同的组合技术,以达到最佳的处理效果。

The Researching Process of Ecological Restoration of Lake Eutrophication

In recent years,with population growth and rapid economic development,and the water resources development and utilization in a irrational condition,the waters became eutrophication as soon as possible.In view of the traditional physical and chemical methods brought about the difficult operation,high costs and easy to produce second-pollution problem,a growing number of people turning to study the ecological renew techniques,such as artificial wetlands,ecological floating bed,biomanipulation,which primary u...
