Embodiment

[0056] First of all, the kitchen waste that has been classified and collected from hotels, restaurants, canteens and food processing places is poured into the heating coarse separation pool. The bottom of the heating coarse separation pool is equipped with a steam heating coil, and the middle is equipped with The upper part of the grille bar is equipped with an automatic reciprocating tooth rake, which continuously rakes the larger debris into the debris pool, and the kitchen waste under the grille bar enters the oil residue separation equipment through the conveyor. In the oil residue separator, the oil and water are separated from the solid organic matter by screw pressing. The solid organic matter is collected and sent to the insect breeding workshop as the main food source of the insects. After 3-5 days, the larvae should be separated from the larvae in time to prevent being bitten by insects. After separation, the pupae should be placed in a ventilated, warm and dry envir...

Abstract

The invention discloses a comprehensive resource treatment method of food waste, relating to the technical field of resource recycle treatment. The comprehensive resource treatment method comprises the technical steps of impurity separation, oil-slag separation, organic solid matter treatment, oil-water separation, liquid grease treatment, wastewater treatment, methane utilization, methane slurry and methane residue utilization, and membrane filtration wastewater treatment. Compared with the traditional treatment process, the comprehensive resource treatment method disclosed by the invention has the advantages that the treated food waste realizes real innocent treatment, the food waste is fully recycled, and organic solid matters, methane, methane residue and methane slurry generated in the treatment process are all most efficiently utilized, thus not only is the food waste hard to be treated in the prior art changed to be valuable, but also the treatment cost is low; and the industrial large-scale production can be realized, and simultaneously great economic and social benefits are also generated.

Description

technical field [0001] The invention relates to the technical field of resource recovery and recycling, in particular to a method for comprehensively recycling kitchen waste. Background technique [0002] Kitchen waste is the most common waste generated in daily life in cities. It belongs to urban domestic waste. Its main components include starchy food, plant fiber, animal protein and fats and other organic substances, with high moisture content, oil and salt content. High, perishable and smelly, which is not conducive to the transportation of ordinary garbage trucks. If this kind of garbage is not classified and specially treated, it will cause great harm to the environment. [0003] Food waste mainly comes from food processing scraps (kitchen waste) and edible residues (swill) generated by the catering service industry, households, and canteens of enterprises and institutions. With the gradual acceleration of urbanization in our country, the output of kitchen waste has ...
