A kind of method for treating kitchen and kitchen waste

Abstract

A method for treating kitchen and food waste comprises the following steps that the kitchen and food waste is put into a receiving hopper to be subjected to pretreatment including bag breaking and coarse crushing, then fed into a transferring storage bin to be stored, then fed into a crusher to be finely crushed, and then fed into an extruder to be extruded for solid-liquid separation; a leachateand sawdust are mixed and then fed into a treatment pool to be subjected to anaerobic and water treatment; and organic solid waste is fed into a dryer to be dried and collected. The method has the innovation points that the leachate, organic solids and inorganic impurities can be efficiently separated in one extruder, thus the separation efficiency of the waste is improved, and the effect of the waste with different components is better treated in the mode of corresponding to the characteristics of the components is achieved.

Description

technical field [0001] The invention relates to the technical field of kitchen and kitchen waste treatment methods, in particular to a kitchen and kitchen waste treatment method. Background technique [0002] Kitchen (kitchen waste) waste, commonly known as slops, also known as swill and slops, is the domestic waste formed by residents in the process of daily consumption. It is easy to rot and deteriorate, emits foul smell, and spreads bacteria and viruses. The main components of kitchen (kitchen waste) waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, waste tableware, plastics, paper towels, fruit peels, fruit stones and other mixed solids. From the chemical composition, there are starch, cellulose, protein, lipid and inorganic salt. The main characteristics of kitchen (kitchen waste) waste are rich in organic matter, high in water content, and perishable. If it is stored for a long time, it will breed germs, mosquitoes, and...

AI Technical Summary

Problems solved by technology

However, it does not specifically discuss the method of solid-liquid separation. For kitchen waste, it will form a paste after extrusion. How to squeeze this paste from the solid waste to reduce the water content of the solid waste to It is still one of the most difficult problems in kitchen waste disposal

At the same time, the kitchen waste cannot be further finely separated, and it cannot be applied to more and more suitable treatment methods, resulting in a waste of energy and the inability to effectively use the kitchen waste.
