EXPANDED POLYPROPYLENE MEDIA IMPREGNATED WITH ACTIVATED CARBON POWDER TO IMPROVE ADSORPTION CAPACITY, POROSITY AND SURFACE AREA, MANUFACTURING METHOD THEREOF, AND BIOFILM FILTRATION APPARATUS USING THE SAME

摘要

PURPOSE: To provided a biofilm media having organic matter adsorption function and maintaining durability manufactured by optimally mixing polymer resin with inorganic material and foaming the mixture, a manufacturing method thereof, and a floating type biofilm filtration apparatus for treating sewage and wastewater more economically and efficiently using the same. CONSTITUTION: The manufacturing method of a media for biofilm process comprises a step of preparing an activated carbon master batch by mixing polypropylene resin with activated carbon powder in a certain ratio; and a step of manufacturing an expanded polypropylene media by injecting and foaming the activated carbon master batch, wherein the activated carbon master batch is prepared by mixing 100 weight parts of the polypropylene resin with 1 to 20 weight parts of the activated carbon powder, wherein the activated carbon powder has a particle size of 10 to 300 m, and wherein the manufacturing method comprises a raw material throwing process(S210), a composite material(activated carbon master batch) preparation process(S220), a mixing process(S230), an ejection process(S240), a foaming process(S250), and a product obtaining process(S260).
