GARBAGE DISPOSAL METHOD, GARBAGE DISPOSAL SYSTEM, AND HEAT TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a garbage disposal method which enable the complete vanishment of garbage over a shorter period of time compared with a conventional method, a garbage disposal system preferable for executing the garbage disposal method, and a heat treatment apparatus utilized in the garbage disposal system.;SOLUTION: In the heat treatment apparatus 15, the garbage heated by superheated steam with the temperature of 180-300°C while stirring and conveying the garbage by a screw conveyer 33, thereby making the garbage low molecular weight without carbonizing polymeric materials contained in the garbage. The garbage heat-treated in the heat treatment apparatus 15 is charged in a decomposition apparatus 17, and a stirring blade 51 is rotated and driven, thereby mixing the garbage with porous ceramic particles 53 with the inhabitation of organic matter degradable microorganisms, and stirring them under the aerobic atmosphere, thus vaporizing, decomposing, and vanishing the garbage.;COPYRIGHT: (C)2006,JPO&NCIPI
