Abstract

The invention relates to the technical field of perishable garbage treatment, in particular to a rapid perishable garbage degradation method and application thereof. Firstly, a degradation bin internally provided with a stirring rod is provided, the stirring rod can be driven by a stirring motor arranged outside the degradation bin, a feeding port capable of feeding perishable garbage is formed in the top of the degradation bin, and a discharging port capable of discharging perishable garbage degradation products is formed in the bottom of the degradation bin; a rapid perishable garbage degradation bacterial agent is detachably fixed to the stirring rod; non-degradable substances are selected from perishable garbage, the perishable garbage is crushed until the perishable garbage passes through a 10-mesh sieve, the perishable garbage is put into the degradation bin, the stirring motor is started to drive the stirring rod to rotate at 30-120 r / min, and aerobic degradation is performed for 24-36 hours; and after degradation is finished, the degradation products are discharged through the discharging port, and residues and liquid are separated and then are treated separately. According to the method, a relatively large amount of the perishable garbage can be degraded in a short time, the perishable garbage is degraded into water and carbon dioxide, and no obvious peculiar smell is generated in the degradation process.

Description

technical field [0001] The invention relates to the technical field of perishable garbage treatment, in particular to a method for rapidly degrading perishable garbage and its application. Background technique [0002] Perishable waste has high water content and low calorific value. If it is incinerated together with other industrial waste and cooking waste, it will not be able to meet the calorific value requirements of waste incineration for power generation. Moreover, perishable waste with high organic matter content will also produce secondary waste when incinerated. Toxic substances such as oxins endanger people's health. The components of perishable garbage mainly include sugar, protein, starch, fat, cellulose and trace elements, etc., which have the characteristics of high organic matter content, rich nutrition, and perishable deterioration. Sanitary landfills are also likely to cause stench, produce a large amount of leachate and methane and other pollution, serious...
