不同人工湿地基质除磷效率研究
Removal Rate of Phosphorus by Different Constructed Wetland Substrates
摘要
Abstract
[ Objective ] The study aimed to discuss the removal rate of phosphorus by different constructed wetland substrates. [ Method ] Based on a static experiment, we analyzed the removal rate and characteristics of phosphorus by different constructed wetland substrates like steel slag, cinder slag, shale, boiler slag, soil and gravel. [ Result ] The maximum adsorption of phosphorus by various substrates showed as follows: steel slag > cinder slag > shale > boiler slag > soil > gravel. When the initial concentration of phosphorus was 5 mg/L, the removal rate of the six substrate was 99.76%, 85.8%, 71.2%, 63.0%, 46.8% and 11.7% respectively. Shale and boiler slag can be used as a substrate under constructed wetland. Cinder slag could be chosen as a renewable substrate for intensifying phosphorus removal. Steel slag could be used at the end of constructed wetlands to treat TP in outflows. [Conclusion] The research could provide theoretical references for choosing a suitable substrate for constructed wetlands to remove phosphorus in future.关键词
