摘要
基于生态学原理的人工湿地污水处理技术已成为人们竞相研究开发的热点。介绍了人工湿地的分类,论述了污染物包括有机物、氮磷污染物、重金属的去除机理的研究进展,分析了湿地植物种类与根系量对污染物去除效果的影响,讨论了湿地结构以及工艺设计的研究情况。最后以人工湿地处理生活用水和工业用水为例综述了人工湿地目前在国内应用的状况。通过以上分析评述发现,人工湿地运行费用低,操作简单,是一种具有前景的污水处理技术, 但在污染物去除机理和实践应用方面还需做更深入的研究。
Constructed wetlands based on the ecological principles are becoming an active research field because of widely applications in wastewater treatment. Firstly introduce the classification of constructed wetlands simply. Then review the research progress on the removal mechanisms of organic pollutants, nitrogen, phosphorus and heavy metal ions by constructed wetlands in detail; analyze the effect of water plants species and biomass of roots to the pollution removal rate also; additionally, discuss the research progress of configures and process design too. At last illuminate applications of constructed wetlands by treating municipal wastewater and industry wastewater. Through analysis, constructed wetlands have widely applied prospects because of low operation fee and simple operation. But do more researches on pollution removal mechanisms and applications in the future.
