【摘要】 水生植物净化修复是一项绿色环保的生态工程技术,能有效地净化富营养化及受污染水体,而且不带来二次污染,有利于重建和恢复水生生态环境,其技术投资和维护成本低,操作相对简单。该文阐述了水生植物修复水体的净化机理以及水体富营养化的消除、重金属的去除、石油化工类及生活类污水的降解、水生植物耐盐性等相关研究成果;介绍了净化塘、人工湿地、生态浮床技术和根际过滤技术在工程实践中的应用;强调了水生植物在净化应用中需关注的技术问题;最后提出了一些可行方法和建议,展望了这种净化技术的发展前景。更多还原

【Abstract】 Phytoremediation is a bioremediation technology,which can degrade or eliminate contaminants from eutrophic water or polluted water without the secondary pollution. It is the least harmful method because it uses natural occurring organisms to preserve the environment in a more natural state. The cost of the phytoremediation is lower than that of traditional processes and the operation is simple. Purification mechanism and effect of hydrophyte phytoremediation were reviewed. Purification pond,artificial wetland,ecological floating bed technology and rhizofiltration technology applied in engineering cases were introduced. The key points of hydrophyte phytoremediation were emphasized. The feasible methods and suggestions were put forward and prospected.更多还原
