Abstract

PURPOSE: To make it possible to select efficiently garbage of high purity, by treating the garbage having been crushed in eddying water in successive steps of removal of metals, removal of rubbers, removal of earth, sand, and glass, and in a concentrating and dehydrating step for the garbage.
CONSTITUTION: Garbage A contained in city refuse is roughly separated by a primary selector 1 of plastics B and inorg. matters C and is delivered as a classified garbage D to a fine selector 2. The selector 2 comprises an impeller crusher, a rotary screen, a rubber-removing screen, a pressure floating-concentrating unit, a centrifugal dehydrator, and separates the garbage from metallic, coarse, heavy materials E, coarse light mateials F such as plastics, rubbish, and inorganic materials G such as glass to form garbage H of high purity. The garbage H is treated anaerobically in a dissolving unit 3 to form a soln. I, which is subjected in a methanizing unit 4 to anaerobic fermentation, hereby methan gas J and a garbage of high purity, contg. 96% fermented material, are obtained in a yield of 90%.
