Zeolite for removal the phosphorous of wastewater and fabricating method for the same

摘要

PURPOSE: A surface reforming zeolite for removing phosphorus and a manufacturing method of the same are provided to improve the absorption efficiency of phosphorus by being coated with sulfate and exchanging sulfate ions and phosphate ions. CONSTITUTION: A manufacturing method of a surface reforming zeolite for removing phosphorus includes the following steps: zeolite and a sulfuric acid aqueous solution are prepared(S101); the zeolite is immersed in the sulfuric acid aqueous solution(S102); and the zeolite is taken from the sulfuric acid aqueous solution and is plasticized at a temperature between 270 and 300 deg C to form sulfate on the surface of the zeolite(S103). The concentration of the sulfuric acid aqueous solution is in a range between 0.1 and 0.3M. The method further includes a sulfate coated zeolite pulverizing process(S104).
