摘要
人工湿地作为近20年来发展起来的一种传统的污水处理技术是一种廉价的替代方案,已越来越受到各国的普遍重视。在本文中,笔者详细介绍了人工湿地的定义、分类、基本构造类型与工艺流程及其在污水净化中的应用领域和应用前景。同时还详细论述了人工湿地的污水净化机理,并对今后研究的方向进行了展望,可为人工湿地污水净化技术的应用研究提供参考。
As a low-cost alternative to conventional sewage treatment, the technology of constructed wetlands developed in recent 20 years has been paid more and more attention to by many countries. In this article, the author provides a detailed review on the definition, composition, design, application of constructed wetlands. At the same time, the paper specifies the mechanism of sewage purification of constructed wetlands and the study trend of constructed wetlands is also discussed.
