Abstract

The invention relates to a method and equipment for storing and pre-treating kitchen wastes. The equipment comprises a shell; a pre-treating unit, a compressing unit, a liquid storing unit, a solid storing unit and an air storing unit are arranged inside the shell, wherein the pre-treating unit is used for crushing the kitchen wastes, the compressing unit is used for compressing the crushed kitchen wastes and realizing solid-liquid separation of the kitchen wastes, the liquid storing unit is used for storing liquid generated by the pre-treating unit and the compressing unit, the solid storing unit is used for storing solids generated by the compressing unit, and the air storing unit is used for storing air generated by the liquid storing unit. By integrating kitchen waste crushing, solid-liquid separation and smelly air collection, the equipment disclosed by the invention is used for pre-treating and storing the kitchen wastes; the pre-treatment is more beneficial for transportation and subsequent anaerobic treatment; the equipment can be widely applied to foodservice industries such as family, community, restaurant and large hotel so as to realize source treatment of the kitchen wastes; the source of kitchen waste pollution is cut off so that bad influences of the kitchen wastes to environment are reduced, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to garbage treatment technology, in particular to a method and equipment for temporarily storing kitchen garbage and pretreating it to realize solid-liquid separation. Background technique [0002] With the improvement of my country's economic strength, people's living standards continue to improve, and the kitchen waste generated by households and catering industries also increases. At present, the amount of kitchen waste produced has a geometric growth trend compared with decades ago. The generation of a large amount of kitchen waste will inevitably bring great harm to the environment. However, my country's food waste treatment industry is in its infancy. The method of anaerobic fermentation capacity treatment is one of the key points of future development. This technology is an advanced treatment of kitchen waste, and there are already mature technological processes and solutions. However, this technology has higher requirem...
