As an essential component of constructed wetland system, filler combines all reactions into a coherent whole and plays an important role in removal of various pollutants in the wastewater treatment process. This paper reviews the progress of research on filler applications in constructed wetlands. The major types of wetland fillers are natural minerals, industrial by-products and modified media. The characteristics, pollutant removal capacity and mechanism, application feasibility and limitation of the major filler types were compared. The prob...
