Embodiment Construction
[0037] Examples such as figure 1 As shown, a method for treating kitchen (kitchen waste) waste is used for subdividing the kitchen (kitchen waste) waste so as to obtain better economic benefits and better environmental protection. The method can be mainly divided into three steps: enzymatic hydrolysis pretreatment, solid-liquid separation, and anaerobic digestion reaction treatment, and each step is connected by a plate chain machine, a screw or a pipeline. The steps of the present invention and the equipment used are described in detail below.
[0038] The kitchen (kitchen waste) garbage contains a large amount of organic matter, which mainly includes some metals, porcelain pieces, plastics, glass fragments, kitchen knives and the like. The garbage is transported to the factory by a special transport vehicle, poured into the unloading bin, and sent to the bag breaking machine through the conveyor belt for preliminary bag breaking. The broken food (kitchen waste) garbage is ...

Abstract
The invention discloses a kitchen waste (food waste) treatment method which is used for fine treatment and anaerobic digestion of the kitchen waste (food waste). The method mainly comprises three major steps of: enzymolysis pretreatment, solid-solution separation and anaerobic fermentation, wherein the steps are connected through plate chain machines and helixes or pipelines. The major innovationpoint is that an enzymolysis process is added in a kitchen waste (food waste) pretreatment process, and the enzymolysis process can promote hydrolysis of proteins in the crushed kitchen waste (food waste), so that a utilization rate of organic substances and a biogas yield at an anaerobic digestion stage are increased; meanwhile, the method realizes efficient separation of dry and wet materials through a high-pressure extruding mode, and is complete in solid-liquid separation; and moreover, pressure is set for quickly separating out organic substance slurry from the kitchen waste (food waste),so that the separating effect is good, and therefore, the kitchen waste (food waste) treatment method can be widely applied to the kitchen waste (food waste) treatment field.
Description
technical field [0001] The invention relates to the field of garbage treatment, in particular to a method for treating kitchen (kitchen waste) garbage. Background technique [0002] Kitchen (kitchen waste) garbage, 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 bacteria, mosquitoes, and cockroaches, and incr...
