调控碳氧水平促进人工湿地脱氮的研究进展
|
摘要
介绍了溶解氧和碳源的主要来源及两者对人工湿地脱氮产生的重要作用;阐述了间歇增氧及补充碳源对湿地碳氧水平的促进机制。认为调控碳氧水平成为促进人工湿地脱氮的有效手段,但亟需经济高效的方法提升人工湿地的碳氧水平。利用藻塘出水可生态调控人工湿地中的碳氧水平,提升湿地脱氮效能。开发利用藻类物质将为优化人工湿地脱氮提供新的研究点,相关技术方法还有待深入研究。
The main source of dissolved oxygen and carbon source and their effects on nitrogen removal by constructed wetlands were introduced; the promotion mechanisms of intermittent aeration and carbon source supplement on carbon and oxygen level of constructed wetlands were explained.Regulation of carbon and oxygen level was considered as an effective method to promote nitrogen removal of constructed wetlands; however cost-effective ways to increase carbon and oxygen level of constructed wetlands were in desperate need. Carbon and oxygen level of constructed wetlands were regulated by utilizing algal substances, which increased the nitrogen removal efficiency of constructed wetlands. Exploitation and utilization of algal substances would provide new research points for nitrogen removal of constructed wetlands, and relevant techniques were still to be deeply explored.
