(4) conveying the useful garbage to a compression box of an extrusion device, extruding 80% of water by high-strength extrusion to form a dry cake, and allowing the extruded garbage sewage to flow into a methane tank or a municipal sewage pipe network through a pipeline;
(5) conveying the garbage formed into the dry cake into a cutting box of a cutting crusher for cutting and crushing to obtain powder;
(6) and conveying the powder garbage to a second separation device with the same structure as the first separation device, destroying residual harmful residues in the powder garbage in a tank body of the second separation device, finally obtaining organic composite soil, and conveying the organic composite soil to a stock yard for stacking.
The further technical scheme of the invention is as follows:
the organic composite soil is used for preparing organic fertilizers.
The organic composite soil and the garbage sewage are used for methane fermentation, and methane formed by fermentation is used as fuel of a high-pressure flame thrower.
The organic composite soil is used for landfill and land reclamation and soil improvement.
Compared with the prior art, the invention adopting the technical scheme has the beneficial effects that:
the problems that the existing garbage treatment process is too high in cost, complex in process, high in consumption, difficult to popularize, secondary pollution and the like are solved, particularly, the pollution-free and zero-emission can be realized by adopting the first separating device and the second separating device for twice aerial flame spraying treatment, the garbage treatment can be fully automated, the cost is ultralow, and the garbage treatment can be completed at one time. The invention has the advantages of large or small treatment mode, high popularization rate, applicability to large and small cities and towns, solves the problems of long-distance transportation, overhigh cost and the like in garbage treatment, and has strong popularization operability and practicability.
