人工湿地污水处理应用现状及发展前景展望

摘要

人工湿地是一种污水生态净化工程技术，因为成本低廉、管理方便、处理效果好而被广泛应用。文章在阐述人工湿地作用原理的基础上，分析了人工湿地在应用研究中出现的问题，探讨了人工湿地在未来科学研究和工程应用中亟需解决的关键技术问题，为人工湿地的研究和工程设计提供一定的参考。%Constructed wetland is a kind of ecological restoration engineering technology which is wide-ly used because of its low cost,convenient management and high efficiency.Based on the principle of con-structed wetland mechanism,this paper analyzes the problems in the application of constructed wetlands, discusses some key technical problems needed to be solved and provides some references to the future sci-entific research and engineering application.
