Bacterium agent for fermentation treatment of waste organic matters and preparation method

Abstract

The invention belongs to the technical field of treatment of waste organic matters. Aiming at solving the technical problems in the prior art that fermentation is low, manual overturning is needed andthe waste organic matters are easy to corrupt in a fermentation process, the invention provides a bacterium agent for fermentation treatment of the waste organic matters and a preparation method. Thebacterium agent comprises a liquid bacterium agent; the liquid bacterium agent is prepared from the following components in parts by weight: 0.005 to 0.015 part of beef extract, 0.02 to 0.04 part ofpeptone, 0.04 to 0.06 part of glucose, 0.002 to 0.006 part of sodium chloride, 101.2 to 101.8 parts of distilled water, 2 to 4 parts of egg white, 0.05 to 0.2 part of sheep serum, 2 to 4 parts of brown sugar, 0.02 to 0.06 part of metabolite of photosynthetic bacteria, 0.02 to 0.06 part of metabolite of saccharomycetes and 0.2 to 0.6 part of an EM bacterium; the bacterium agent further comprises acarrier; the weight ratio of the carrier to the liquid bacterium agent is (20 to 30) to 1; the carrier is composed of organic matter particles with the mesh quantity of 10 to 20 meshes. The bacteriumagent provided by the invention has the characteristics of manpower saving and capabilities of prolonging the fermentation time and improving the fermentation efficiency, and is suitable for the wasteorganic matters with high aerobic fermentation difficulty.

Description

technical field [0001] The invention belongs to the technical field of waste organic matter treatment, and in particular relates to a bacterial agent used for waste organic matter fermentation treatment and a preparation method. Background technique [0002] At present, with the development of cities and the increase of population, the output of organic wastes is rising rapidly. How to efficiently treat these organic wastes with "reduction, harmlessness, and recycling" has become a common concern of the society. . Among them, organic domestic waste, kitchen waste, leftovers from the food processing industry, organic sludge, and livestock manure all have the common characteristics of high organic matter content and biodegradability, and are collectively referred to as biodegradable waste organic matter. [0003] At present, people often use heap retting method, combustion gasification method, supercritical water oxidation method, incineration power generation mode anaerobic ...

AI Technical Summary

Problems solved by technology

[0004] However, the inoculum used to cultivate fermenting bacteria in the existing biological treatment methods is often not ideal

With the activity of microorganisms, the temperature of the bacterial agent is constantly changing. Due to the poor overall air permeability of the existing bacterial agent, heat accumulates in various parts, which leads to an increase in local temperature and affects the activity of the fermentation bacteria, thereby affecting its effect on the fermentation process. The decomposition of organic substances leads to poor decomposition effect, and the existing bacterial agents are often only conducive to the growth of a single strain. When the local temperature is too high or too low, it will have a greater impact on the fermentation bacteria, and even Stop the fermentation, thereby reducing the fermentation efficiency; in addition, because the treatment process takes a certain amount of time, the discarded organic substances are easy to corrupt and produce odor during the treatment process
