Abstract

The invention particularly relates to a food residue and kitchen waste co-processing system and co-processing method. The food residue and kitchen waste co-processing system comprises a food residue processing mechanism, a kitchen waste processing mechanism, a full-mixing anaerobic mechanism, an incineration mechanism and a grease storage mechanism, wherein the kitchen waste processing mechanism is suitable for carrying out pressure filtration and impurity removal and three-phase separation on slurry produced by the kitchen waste processing mechanism and the food residue processing mechanism so as to obtain solid residue, an organic solid phase, a water phase and an oil phase; the full-mixing anaerobic mechanism is suitable for anaerobic fermentation to obtain biogas, biogas slurry and biogas residue; the grease storage mechanism is suitable for storing grease; and manual sorting is replaced with an efficient and stable automatic sorting assembly, manpower is saved, safety and environmental protection are achieved, the number of food residue processing mechanisms is reduced under the treatment condition of the kitchen waste processing mechanism, the equipment utilization rate is increased, three-treatment of food residue is further deepened, the oil extraction procedure is added, and grease in the food residue is effectively extracted.

Description

technical field

[0001] The invention belongs to the technical field of waste sorting and processing, and in particular relates to a system and method for collaborative processing of kitchen waste and kitchen waste. Background technique

[0002] The existing kitchen waste treatment process is bag breaking + manual sorting + solid-liquid separation by pressing + wet anaerobic / dry anaerobic. Solve the problem of wrapping plastic bags in kitchen waste by breaking bags, sort out inorganic substances in kitchen waste by manual sorting, such as plastic bags, fabrics, plastic bottles, ironware, etc., and the sorted materials enter the pressing equipment The solid-liquid separation is realized, the solid residue is subjected to dry anaerobic fermentation or incineration, and landfill treatment, and the slurry enters the water treatment system or undergoes wet anaerobic fermentation.

[0003] Manual sorting in the prior art has low efficiency, high labor costs, potential safety hazar...
