Biofilm media having elemination function of nitrogen waste water and its preparing method

摘要

A carrier for purifying wastewater having a removal property of nitrogen and phosphorous and a manufacturing method thereof are provided to remove the nitrogen and the phosphorous steadily by using fiber having an anion-exchange function and a ceramic member. A manufacturing method of a carrier for purifying wastewater comprises the following steps of: producing an ion adsorption and removing pad having an ion-exchange function(S100); producing a ceramic member including magnesium and calcium composition(S200); and filling the ceramic member into a fabric pad(S300). The polymeric fiber used for the fabric pad is the fiber made of animal hair like wool and synthetic fiber including natural fiber or polypropylene, polyethylene, and nylon etc.
