Kitchen waste garbage biological treatment integrated equipment and method

Abstract

In order to solve the problems that a conventional kitchen waste garbage biological treatment technique is complex in technology, low in efficiency and the like, the invention provides kitchen waste garbage biological treatment integrated equipment and method. The integrated equipment comprises a magnetic separation unit, a nonmagnetic metal separation unit, a garbage breaking unit, a reaction warehouse and an organic fertilizer breaking and granulating unit, wherein the units are sequentially connected through a transmission pipeline; the reaction warehouse adopts a tank sealing structure; and a liquid collecting pipeline, a liquid spraying pipeline, an air inlet pipeline, an air outlet pipeline, a stirring auger, a heating device, a temperature probe, an oxygen probe, a nitrogen probe and a methane probe are arranged. The integrated method adopts the kitchen waste garbage biological treatment integrated equipment for biological treatment on kitchen waste garbage. The kitchen waste garbage biological treatment integrated equipment and method have the beneficial technical effects that the kitchen waste garbage can be subjected to efficient biological treatment in a disposable manner by the integrated equipment, methane and organic fertilizers are obtained, secondary pollution cannot be caused, and the kitchen waste garbage biological treatment integrated equipment and method are simple to operate and high in practicality.

Description

technical field [0001] The invention relates to the biological treatment technology of kitchen waste, in particular to an integrated equipment and method for biological treatment of kitchen waste. Background technique [0002] Kitchen waste is one of the main components of urban domestic waste, and the catering industry, households, and fruit and vegetable wholesale markets will generate a large amount of kitchen waste. Kitchen waste has the characteristics of high organic matter content, easy to go bad, and easy to breed bacteria and pathogens. Improper disposal will cause a series of environmental and social problems, as well as food safety problems such as "gutter oil" and "garbage pigs". At present, the kitchen waste treatment technologies include incineration, anaerobic digestion, aerobic composting, landfill and crushing straight discharge, etc. Among them, the anaerobic digestion technology oriented to harmless treatment and resource utilization is considered to be th...
