Kitchen garbage high-temperature aerobic composting system

Abstract

The invention discloses a kitchen garbage high-temperature aerobic composting system. The system comprises a garbage crushing assembly, an oil and salt removal assembly, an iron removal assembly and a composting system. According to the kitchen garbage high-temperature aerobic composting system, sufficient pretreatment of kitchen garbage is realized, the treated garbage is completely crushed, the subsequent aerobic composting process is facilitated, the composting time is greatly shortened, the effect is obviously improved, and recycling of the kitchen garbage is realized.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a high-temperature aerobic composting system for kitchen waste. Background technique [0002] Kitchen waste refers to perishable organic waste such as fruits and vegetables, food scraps, leftovers, melon and fruit peels, and other metal, glass and other wastes discarded in daily life. Kitchen waste has the characteristics of high organic matter content, high moisture content, high oil and salt content, etc., and needs to be properly treated. [0003] The increasing production of kitchen waste is placing a heavy burden on the environment's ability to heal itself. How to effectively dispose of kitchen waste and how to dispose of it in a green and sustainable manner has become one of the current environmental problems. [0004] In addition to being "hazardous", kitchen waste also has the characteristics of "resources". Proper disposal will produce good environm...

Problems solved by technology

[0006] Feed treatment technology has the advantages of high degree of mechanization, high degree of resource utilization, and small footprint, but it cannot avoid the problem of protein homology, which is controversial in the industry. At the policy level, there is no decision on the use of food waste as feed. As the main promotion process of kitchen waste treatment

Composting treatment technology has the advantages of simple composting technology; but it is easy to produce unpleasant smell, affect the surrounding environment, and cause soil salinization

Aerobic biological treatment technology has the advantages of short processing time and high degree of automation; but the input cost is high and the processing capacity of a single device is limited

Anaerobic fermentation treatment technology can realize harmlessness and resource utilization, comply with the national energy policy, maximize the recovery of oil in kitchen waste, purify or process it into industrial raw materials, and prevent waste oil from returning to the dining table; The process is relatively complex, the investment recovery period is long, and the stability of equipment operation in the process of industrial utilization is high. The degree and adequacy of garbage crushing will directly affect the treatment effect. The crushing and cleaning effects in the process are not good, which restricts the subsequent fermentation process
