PURPOSE: A method for preparing a purifying media to which nutrition is supplied for active coherence of microorganisms in an aeration tank is provided to dissimilate sewage, waste water and nitrogen compound for purification by preparing a porous nutrition media in a form of irregularities, thereby irresistibly forming an initial biofilm for early active coherence of microorganisms. CONSTITUTION: The method for preparing a purifying media comprises the processes of mixing waste polyethylene chip, used briquette, quartz sand earth, loess, and chaff in a mixer (1); storing the mixed raw materials in a storage tank; transferring the mixed raw materials stored in the storing process to a hopper (4); extruding the mixed raw materials fed into the hopper for flowing into a dissolving pipe; transferring the raw materials to a primary preheated first solution tank (3) by the extruding process; dissolving the raw materials in a dough state for flowing into a second solution tank (7); adding chaff to the mixed raw material; forming inner and outer surfaces in a form of irregularities by passing the chaff added mixed raw materials through an irregular sponge body porous forming pipe; cooling the formed product in a first cooling water vessel (10); transferring, cooling and forming the formed product again in a second cooling water vessel (12); and detaching the product from a forming frame (9) of the second cooling water vessel (11), packing and transporting the product.
