摘要
碳源作为反硝化过程的电子供体,是人工湿地脱氮过程的关键性限制因素。合理的碳调控策略被认为是促进人工湿地脱氮的有效手段。介绍了湿地中碳的主要来源和其在脱氮过程中的作用,系统梳理了近年来国内外有关人工湿地碳调控策略的研究成果,阐述了现有碳调控策略的优缺点,最后,对人工湿地碳调控的研究发展方向进行了展望。
As an electron donor in the denitrification process, carbon source is a key limiting factor in nitrogen removal process of constructed wetlands. Reasonable carbon regulation strategy is considered to be an effective way to promote nitrogen removal of constructed wetlands. This paper introduced the main sources of carbon in constructed wetlands and their role in nitrogen removal process, systematically reviewed the research results of carbon regulation strategies in constructed wetlands at home and abroad in recent years,expounded the advantages and disadvantages of existing carbon regulation strategies. Finally, the research and development directions of carbon regulation on constructed wetlands were prospected.
