Kitchen waste treatment method and equipment

Abstract

The kitchen waste treatment method comprises the following steps of S1, crushing; S2, blending of additional waste materials; S3, aerobic fermentation; and S4, microbial deodorization. Kitchen waste treatment equipment used in the S3 comprises a shell and a control cabinet, and a reaction bin, a discharging bin and an air distribution chamber are arranged in the shell; the reaction bin is provided with a cover plate, and a first partition plate and a second partition plate are arranged in the shell; the cover plate is provided with a feeding port, a waste gas discharging port, a temperature probe and a humidity probe, and the cover plate is provided with a gear motor; the gear motor is connected to a stirring paddle; an electric heating resistor is arranged in the reaction bin; the first partition plate and the second partition plate are provided with air holes, and the first partition plate is further provided with a discharging hole; a discharging valve is arranged on the outer side of the shell; and a discharging port is formed in the side wall of the discharging bin, and an air blower is arranged on the outer side of the air distribution chamber. When the kitchen waste treatment method and equipment are used for treating the kitchen waste, the whole process is high in fermentation rate, free of waste water, small in waste gas amount, high in integration degree, and very suitable for kitchen waste treatment.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and relates to a garbage treatment method and equipment, in particular to a low-energy kitchen waste treatment method and equipment without waste water generation. Background technique [0002] At present, with the continuous in-depth promotion of waste classification policies across the country, higher requirements are put forward for waste management technology. According to the survey, kitchen waste (community households, vegetable markets, leftovers, fruit, vegetable and melon skins and other perishable organic matter) accounted for about 59% of urban domestic waste, and there is an increasing trend year by year. Kitchen waste contains oil and water. , high salt content, high content of organic matter such as crude protein and crude fiber, but it is not resistant to storage and transportation, and it is easy to rot and deteriorate to produce odor, viruses and pathogenic bacteria. If...

AI Technical Summary

Problems solved by technology

Among them, the general development trend of sanitary landfill technology is that its proportion is getting smaller and smaller due to problems such as explosion caused by the accumulation of biogas, site leakage or secondary pollution of leachate; There are also problems that unstable incineration affects power generation production, unfavorable flue gas treatment leads to air pollution, and organic waste has low calorific value and needs pretreatment before incineration
