Wet garbage large-capacity centralized treatment three-waste-free rapid decomposition system and rapid decomposition method

Abstract

The invention discloses a wet garbage large-capacity centralized treatment three-waste-free rapid decomposition system and a rapid decomposition method. The system comprises a wet garbage temporary storage pool, a sorting platform, a crushing extruder, a biodegradation system and a waste gas purification system, wherein the biodegradation system comprises a biodegradation bacteria bed and a turning and throwing machine; the biodegradation bacteria bed comprises a padding layer and a wet garbage layer; a mixture of padding and biodegradation flora is laid on the padding layer; the biodegradation flora is mainly a mixture of bacillus subtilis, bacillus pumilus, bacillus licheniformis and acinetobacter calcoaceticus; and the turning and throwing machine is an automatic bottom-making turning and throwing machine with a gear and a shovel, and materials on the biodegradation bacteria bed are turned and thrown once at certain intervals. The wet garbage biodegradation rate can reach 99%, the problem of wet garbage large-capacity centralized treatment is thoroughly solved, the problem of three-waste storage in wet garbage treatment is thoroughly solved, and the three wastes are not reducedbut almost not quantified; and one-time treatment is achieved to reach the standard.

Description

technical field [0001] The invention belongs to the technical field of wet garbage treatment, and relates to a wet garbage treatment system and a treatment method, in particular to a large-capacity centralized treatment of wet garbage without three-waste rapid decomposition system and a rapid decomposition method. Background technique [0002] Wet garbage is garbage that will rot, including leftovers, rotten vegetable leaves, animal and fish viscera, waste residue of melon skin and fruit core, expired food and other food waste produced in the kitchen of family life. At present, the processes of on-site and nearby treatment facilities for wet garbage mainly include: microbial fermentation to make fertilizer, microbial degradation (decomposition, elimination type), physical crushing and extrusion dehydration, natural fermentation after crushing, etc. [0003] The existing wet garbage microbial degradation method is difficult to achieve centralized large-capacity treatment (mor...

AI Technical Summary

Problems solved by technology

[0003] The existing wet garbage microbial degradation method is difficult to achieve centralized large-capacity treatment (more than 100 tons per day), and there are problems in the process of treatment, such as the emission of odor to the environment, the existence of a large amount of waste water and waste residue, and the low utilization rate of resources; and , the larger the treatment capacity, the more the three wastes (waste water, waste gas, waste residue), the longer the treatment cycle, the lower the efficiency, and the higher the cost
