摘要
PURPOSE: A combined treatment system of garbage and sewage sludge is provided to stabilize organic matter of high concentration through anaerobic digestion process by combining the garbage with concentrated sewage sludge after shredding garbage through pre-treatment process and separating miscellaneous materials from the shredded garbage. CONSTITUTION: The combined treatment system of garbage and sewage sludge using automatic crushing and sorting machine comprises a storage tank(20) for preventing cavitation of garbage introduced into a shear shredder(30); a shear shredder(30) and magnetic separator(31) for primarily shredding the garbage transferred from the storage tank(20); first storage tank(40) for temporarily storing the garbage shredded in the shear shredder(30); an automatic crushing and sorting machine(50) for crushing the primarily shredded garbage to a particle size required by the minimum mechanical load and removing miscellaneous materials at the same time; magnetic sorter(51) and second storage tank(54) installed at the lower part of the automatic crushing and sorting machine(50) to finally separate fine metallic materials such as fish-hooks; a fine sorter(60) in which the miscellaneous materials such as vinyl, can, scissors, rubber gloves separated from the automatic crushing and sorting machine(50) are dehydrated and separately discharged by compression of a screw so that the discharged materials can be reclaimed or separately treated; third storage tank(63) for storing a crushing liquid completing the garbage pre-treatment through the above processes; deodorization facility(80) for removing malodor generated from the pre-treatment process; and equipment for producing methane from the pre-treated garbage crushing liquid through operation of an anaerobic digestion tank(70).
