DG-Ca-Based Bio-Filter Media for Denitrification and Phosphorus Removal is specially developed for pollutants such as phosphorus, ammonia-N, and total nitrogen in sewage. Through optimized process formulation, incorporation of special nano-active components, and special processing techniques, this unique bio-filter media is produced with high porosity, high strength, large phosphorus adsorption capacity, and fast adsorption rate. It enables selective adsorption/precipitation conversion of phosphorus on the media surface, thereby achieving the removal of phosphorus from sewage. Meanwhile, this media serves as a carrier for microbial growth; through bio-chemical synergistic effects, it realizes the goals of deep denitrification, phosphorus removal, and decolorization.
