The role of fillers is the main mechanism of phosphorus removal in constructed wetland system.The phosphorus removal target of constructed wetland can be achieved through the interception and adsorption of fillers and complexation precipitation.Therefore,the key to improve the phosphorus removal capacity of constructed wetlands is how to select fillers with high phosphorus removal function.This paper reviews the research progress of phosphorus removal fillers in constructed wetlands at home and abroad,introduces the types of phosphorus removal fillers at home and abroad,their application advan...
