The invention provides a wetland denitrifying filler, which can stably provide a carbon source for a denitrifying process of a wetland, and select different specifications to control the release rateof the carbon source according to different conditions; the spherical shape and the regular multi-via design of the filler can prevent the wetland from being blocked; a material of completely degradable plastic is harmless to the environment, is from stable sources, and can meet the needs of large-scale production; the invention also provides application of the wetland denitrifying filler; by mixing the wetland denitrifying filler and limestone in proportion and filling the horizontal subsurface wetland as the denitrifying carbon source, and denitrifying bacteria complete the denitrifying process through biodegradation and adsorption in an anaerobic environment provided by the horizontal subsurface wetland, and effectively remove total nitrogen; by mixing with a phosphorus removal materialand adding, phosphorus re
