NOVELTY - Processing and recycling harmless comprehensive kitchen waste comprises: processing kitchen waste in a material receiving device including a turnover hopper and a preset broken bags host warehouse; pulverizing; sorting; carrying out hydrolytic acidification on processed material to obtain fermented raw material, and passing the fermented material into pre-stored liquid slag pool; pulping; and conducting anaerobic fermentation of fermented raw material, and processing into biogas substances, residual slurry material and biogas residue material.    USE - The method is useful for processing and recycling harmless comprehensive kitchen waste (claimed).    ADVANTAGE - The adoption of mechanical pre-treatment and post-anaerobic fermentation technology, kitchen waste can be treated in a large scale, so that energy resource recovery of kitchen waste can be realized. Various impurities are prevented from causing failure to the operating device to the maximum degree by multiple impurity removing processes, so that the whole flow is smooth, safe and long in service life. Through serial flows, initial kitchen waste is treated as biogas materials and improved soil materials with high value, so that resource utilization of waste is realized. The whole process flow is simple, convenient and reasonable and good in treating effect.    DETAILED DESCRIPTION - Processing and recycling harmless comprehensive kitchen waste comprises: receiving materials and breaking bags: adopting a material receiving device including a turnover hopper and a preset broken bags host warehouse, pouring the external kitchen waste into the preset hopper, allowing the hopper to start flipping prefabricated kitchen waste and dumping into a broken bag host warehouse, and shredding the waste food by built-in bag-breaking device in the broken bags host broken bag host warehouse, so as to obtain bulk waste material; pulverizing: discharging the waste material from lower material outlet conveyor of material receiving device, and passing into the grinder inlet via a conveyor, and starting the grinder to crush the waste material into smaller waste material; sorting: delivering the smaller waste materials into the sorter inlet, where the sorter outlet is divided into organic matter outlet and miscellaneous material outlet, then starting the sorter to process the smaller waste materials into coarse organic matter and sorting mixed substances, and discharging separately from the organic material outlet and miscellaneous substances outlet; hydrolytic acidification: transporting the coarse organic matter into an acidification tank, carrying out hydrolytic acidification on processed material to obtain fermented raw material, and passing the fermented material into pre-stored liquid slag pool; pulping: passing the sorted miscellaneous material into presser inlet, starting the presser for pressing sorted mixed material of raw fermented material and residual material, and storing the pressed raw fermentation material in a liquid tank; anaerobic fermentation: delivering the liquid slag pool fermented raw material to the fermentation tank, processing into biogas substances, residual slurry material and biogas residue material.
