摘　　要：人工湿地作为一种绿色生态、低成本的污水处理技术,其应用日渐广泛。随着应用和机理研究的深入,传统湿地在运行过程中也涌现出各种问题。本文总结了近几年来人工湿地污水处理所出现的堵塞、脱氮效率低、污染负荷小、受温度影响大等问题,综述了国内外学者针对这些问题采取的内部系统强化、工艺改进以及与其他工艺类型组合等措施,并对今后人工湿地技术的发展方向进行探讨。As a green and low-cost wastewater treatment technology, constructed wetlands are widely applied in many fields in recent years. However, previous research also revealed that some problems occurred frequently during the running process of constructed wetlands. This paper summarized these problems such as clogging, low nitrogen rembVal efficiency, low pollution load, and temperature dependence. Meanwhile, methods to strengthen treatment efficiency, like intern intensification, technique improvement and instrument assembly, were also reviewed in this paper. Furthermore, the trend of technology development was discussed.
