(3) the garbage as resource classification is disposed and is utilized overall process, to the processing of classifying of described inorganic matter, partly plastic paper and humified material, described classification is handled and is comprised: to the direct resource recycling of metal, bottle, jar implementation that sub-elects from described inorganic matter, article to described partly plastic paper class are used for regeneration, to described humified material ferment, compost treatment, output biogas and organic fertilizer;

(4) combustible gas combustion power generation comprises: pyrolysis gas and biogas in step (2) and the generation of (3) back feed combustion power generation in the internal combustion engine.

Municipal refuse has distinct time and space characteristics, and last from the time, it only is present abandoned material, and As time goes on, the use of technology, the discarded object of today just can become the resource for tomorrow; From space angle, the material that rubbish only goes out of use with respect to a certain process or a certain place, and in another occasion, it just can become useful material for certain purposes; And if in addition recycling to municipal refuse, then major part can fully utilize, such as, 87% material can be fully utilized in the municipal refuse of Guangzhou at present, if with the base soil of lime-ash as construction, then can all be utilized.For example, 1 ton of scrap iron and steel of every recovery can be made steel 0.9 ton, and than saving cost 47% with ore smelting, air pollution reduces 75%, and water pollutes and reduces by 97%; The junked tire of " retired " can be reduced into expensive fuel oil on automobile, motorcycle; The fertilizer that utilizes rubbish from cooking to make through the biotechnology compost is the most natural, top quality fertilizer.

The present invention compared with prior art, has following advantage: in the rubbish comprehensive utilization factory that has set up, develop the comprehensive garbage disposal that integrates refuse classification, compost, pyrolytic incineration heat supply, gasifying electricity generation, composting technology and utilized complete set of equipments, formed domestic waste recycling system;

Realize rubbish automation compounding separation simultaneously, by making up refuse classification technology such as big material choosing, broken bag, magnetic separation, screening, selection by winnowing, wet concentration, hook choosing, solved the adhesion of crude waste component height, twined, mixed, not segregative difficult problem, realized effective sorting of rubbish complex component;

Refuse pyrolysis is burned and low heat value gasifying electricity generation combination technique is applied in the processing procedure, solved traditional burning based on the solid phase fuel burning, each component difference burning time is big, fuel incomplete, it is wayward to burn, difficult problem secondary pollution; The generation, the minimizing exhaust emissions amount that effectively suppress dioxin simultaneously, stable heating power and the electric power that capacity is provided of the system that can be;

Domestic waste aerobic-the efficient fermentation technique of anaerobism aspect, solved that urban house refuse fermentation starting is slow, the cycle is long, bacterial classification is cultivated and the circulation difficulty, easily caused an acidosic difficult problem, developed simultaneously at organic fertilizer production technology that can rotten organic matter recycling;
