The Efficiency and Research Prospect of the Disposition of Sewage by Constructed Wetland

This paper mainly elaborated the current research situation of the disposition of sewage by constructed wetland and its elimination efficiency of organic substances, nitrogen and phosphorus. It analyzed the factors that may affect the efficiency of disposition of sewage and showed that such factors as the types of constructed wetland, the categories of its plants, the categories and quantity of its microorganism, the temperature, the stay and load of water power as well as the operating management of constructed wetland ect. can influence the efficiency of the disposition of sewage by constructed wetland. According to the current situation of the research and application during which the constructed wetland is used in the disposition of sewage, this paper pointed out the direction for future research.
