The diameter of the sieve hole of the bouncing sieve is 2-3mm, and the bouncing sieve is suitable for bouncing and screening materials pulped by the hydrapulper, so that paper pulp and sewage flow down from the sieve hole of the bouncing sieve, and the rest materials are bounced and separated from the upside. The mesh openings of the inclined screen are 60-80 meshes, the inclined screen is positioned below the bouncing screen and is suitable for separating paper pulp and sewage flowing down from the mesh openings of the bouncing screen, wherein the sewage flows out from the mesh openings of the inclined screen, and the paper pulp slides downwards along the upper surface of the inclined screen. It should be noted that the inclined screen is an obliquely arranged screen, and the pulp herein includes paper and leaves, but the content of the leaves is relatively small, and is referred to as pulp herein.

The pulp press is suitable for pressing pulp separated by the inclined screen to obtain finished pulp and extrude sewage. The sewage treatment unit is suitable for performing sewage treatment on sewage flowing out of meshes of the inclined screen and sewage generated by extrusion of the pulp press to obtain clear water and sludge; wherein fresh water is suitable for being supplied to the washing unit for washing. The sewage treatment unit can realize the cyclic utilization of sewage, and is very environment-friendly.

The fermentation unit is suitable for fermenting the residual materials sorted by the second negative pressure adsorption sorting unit and the residual materials sorted by the bouncing screen.

The third negative pressure adsorption sorting unit is suitable for performing negative pressure adsorption sorting on the materials fermented by the fermentation unit so as to sort out fibrous organic matters, kitchen waste organic matters and granular inorganic matters.

And the electromagnetic eddy current sorting machine is suitable for performing electromagnetic eddy current sorting on the residual materials sorted by the third negative pressure adsorption sorting unit so as to sort out non-magnetic conductor metals.

The landfill treatment unit is suitable for landfill of the residual materials separated by the electromagnetic eddy current separator, the sludge treated by the sewage treatment unit and the residual materials separated by the manual separation unit. It should be noted that, because the materials such as plastics and metals are sorted out, part of the landfill is the materials such as silt which can be directly buried, and the environment is not affected.

The process completes the terminal accurate classification of the garbage, and realizes the reduction discharge, the harmless treatment and the resource utilization.
