Abstract

The invention discloses a kitchen waste and sludge collaborative treatment system and method. The system comprises screen type separation equipment for screening kitchen waste, crushing and separationequipment for crushing and separating the small kitchen materials obtained after screening, oil-water separation equipment for carrying out oil removal treatment on the kitchen slurry separated out by the crushing and separation equipment, collaborative pulping equipment for mixing the sludge and the kitchen slurry after oil removal treatment and anaerobic digestion equipment for carrying out anaerobic digestion on the mixed slurry prepared by the collaborative pulping equipment. After the kitchen waste is subjected to classification and separation and slag removal, the content of inorganic matter can be reduced, and the anaerobic fermentation efficiency is improved. Meanwhile, the internal abrasion of a tank body is reduced. On one hand, the oil removal treatment can collect the waste oil for reutilization (such as preparing of biodiesel), so that the project benefit is increased; and on the other hand, the grease content and the specific adhesion and isolation characteristics of grease in the slurry can be reduced, and the anaerobic reaction effect is increased after the grease is removed.

Description

technical field [0001] The invention belongs to the technical field of organic solid waste treatment equipment, and in particular relates to a system and method for collaborative treatment of kitchen waste and sludge. Background technique [0002] Kitchen waste, commonly known as swill, also known as swill and swill, 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 food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. From the chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. The main characteristics of food waste are high moisture, high salinity, and high organic matter content. It is easy to rot and deteriorate, and breeds germs. If it is not disposed of properly, it will have a bad impact on the physical and mental health of residents, such as...
