摘要
人工湿地作为近20年来发展起来的一种廉价的替代传统污水处理技术的方案,越来越受到世界各国的普遍重视。与传统的污水处理法相比,人工湿地具有基建和运行费用低,操作与维护简单等优点。介绍了人工湿地污水处理技术的机理和优缺点,以及人工湿地在我国的研究和应用,并对其未来的发展趋势和可能改进的方向做了分析。
As a low cost alternative to traditional wastewater treatment process, the technology of constructed wetland （CW） had been used in wastewater treatment for the last 20 years, and got growing attention worldwide. This paper reviews the mechanisms and advantages and disadvantages of the constructed wetland specialized in wastewater treatment. Compared with conventional treatment systems, constructed wetland technology is cheaper in construction and maintenance and easier to operate. The current situation of research and application of the CW system was summarized in China. The future development and the possible ways to improve the system were also discussed.
