人工湿地对污水脱氮除磷的研究进展

onstructed wetlands，as a new kind of wastewater treatment technology ,are widely studied and used in Nitrogen and Phosphorus removal. On the basis of introducing the mechanism of Nitrogen and Phosphorus removal and connecting the latest research achievements of the study of constructed wetlands, the paper systematically described the development about the study of influencing factors in Nitrogen and Phosphorus removal to wastewater. Influencing from the microorganisms and substrate in the constructed wetland were emphasized in the paper, with DO, pH, temperature , and influencing of organic acid to Phosphorus removal was added. The paper will facilitate using all kinds influencing factors, better and comprehensively, and provided reference for designing and optimizing the wetlands, and enhanced capability of N and P removal.
