Perishable Garbage Rapid Degradation Method and Its Application

Abstract

The invention relates to the technical field of perishable garbage treatment, in particular to a method for rapidly degrading perishable garbage and its application. Firstly, a degradation bin with a stirring rod inside is provided. The stirring rod can be driven by a stirring motor arranged outside the degradation bin. There is a discharge port that can discharge the degradation products of perishable garbage; detachably fix the fast-degrading bacterial agent of perishable garbage to the stirring rod; pick out non-degradable substances from perishable garbage, crush them to pass through a 10-mesh sieve, and place them in the In the degradation chamber, the stirring motor is turned on to drive the stirring rod to rotate at 30-120r / min, and the aerobic degradation takes 24-36 hours; after the degradation is completed, the degradation products are discharged through the discharge port, and the slag liquid is separated and processed separately. The method can complete a relatively large amount of degradation treatment of perishable garbage in a short period of time, and degrade it into water and carbon dioxide, and no obvious peculiar smell is generated during the degradation process.

Description

technical field

[0001] The invention relates to the technical field of perishable garbage disposal, in particular to a method for rapid degradation of 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 wastes such as industrial waste and decoction waste, it cannot meet the calorific value of waste incineration for power generation. Moreover, perishable waste with high organic matter content will also produce two when incinerated. Toxic substances such as oxin endanger people's health. The components of perishable garbage mainly include sugar, protein, starch, fat, cellulose and trace elements, etc. It has the characteristics of high organic matter content, rich nutrition, and perishable deterioration. Sanitary landfills are also prone to odor and produce a large amount of leachate and biogas. and other pollution, seriously endangering surface water, g...
