摘要
堵塞是人工湿地污水处理技术中存在的主要问题。随着人工湿地的不断推广与应用,堵塞问题也受到越来越多人的关注。介绍了人工湿地堵塞的影响因素及相关的数学模型,从物理、化学、生物等3个方面分析了人工湿地堵塞的机理,并提出了在湿地设计与运行中采取的一些避免堵塞的措施,最后,简单介绍了国内外学者采用人工湿地预处理工艺来延缓堵塞发生所取得的研究成果。
Clogging is the main problem of wastewater treatment technologies in constructed wetlands.With the increasing promotion and application of constructed wetlands,more and more people pay attention to this problem.The factors causing the clogging in constructed wetlands,as well as several mathematical models related to the clogging are introduced,and the clogging mechanism of constructed wetlands are analyzed from the physical,chemical and biological aspects.Some measures to avoid clogging during wetland design and operation are put forward.At the end,the research achievements in postponing clogging by the pretreatment technologies in constructed wetlands are briefly reviewed.
