人工湿地用于城市污水厂尾水深度处理及其脱氮效能强化研究

Study on advanced treatment of tail water from wastewater treatment plant by constructed wetland and enhancement in denitrification efficiency

综述了人工湿地(constructed wetland,CW)用于城市污水处理厂尾水深度处理的效能,面向CW用于城市尾水强化脱氮需求,从溶解氧调控、基质优化、微生物强化、碳源投加等方面分析了强化途径,为进一步研究及CW在城市污水厂尾水深度处理应用提供了借鉴。

This paper summarizes the effectiveness of constructed wetlands for advanced treatment of tail water from urban sewage treatment plant.In order to meet the enhanced demand for denitrification in urban sewage treatment,the enhancement approaches are suggested,including regulation of dissolved oxygen,optimization of matrix,enhancement by microbial and addition of carbon source.It aims to provide a reference for further research and application of constructed wetland in deep treatment of tail water from urban sewage treatment plant.
