摘要
Abstract
To address the technical bottleneck of efficient and stable phosphorus removal in surface flow wetlands,this study aims to effectively enhance the stable phosphorus removal performance of natural and surface flow constructed wetlands.Bentonite and limestone were used as the main components,and modi-fication was performed through drying and high-temperature calcination.A comparative analysis of the phosphorus removal performance of the modified fillers was conducted.The results showed that the physi-cal structure of the raw material was improved,the specific surface area reached 10～18 m2/g,and the mes-oporous distribution tended to be dense.The removal efficiency of soluble phosphate was up to 70％～90％,and the maximum saturated adsorption capacity was between 0.220 mg/g and 0.992 mg/g.In this study,a new type of environmentally friendly material was developed,which can be used as a reference for improving the phosphorus removal efficiency of natural and surface flow constructed wetlands.关键词
