Problems solved by technology

At present, the main bacterial agent of the aerobic digestion method is a single aerobic bacterial agent or a compound bacterial agent composed of multiple aerobic bacterial species. Their disadvantage is that the oxidation process consumes a large amount of oxygen, resulting in a local anaerobic environment. At this time The degradation of aerobic bacteria is inhibited, reducing the rate of decrement

Embodiment example 1

[0023] The compound bacterial agent is prepared according to the following ratio: 80% of Pseudomonas, 10% of Enterococcus and 10% of Enterobacter. After sorting the catering waste, add the compound bacterial agent according to 0.1-8% of the total amount of garbage, turn it over every 0.5 hours, keep ventilation, and react for 24-48 hours at 25-40 degrees Celsius, which can reduce the waste. Volume 99% effect.

After sorting the catering waste, add the compound bacterial agent according to 0.1-8% of the total amount of garbage, turn it over every 0.5 hours, keep ventilation, and react for 24-48 hours at 25-40 degrees Celsius, which can reduce the waste. Volume 99% effect.

Embodiment example 3

[0027] The compound bacterial agent is prepared according to the following ratio: 60% of Pseudomonas, 20% of Enterococcus, and 20% of Enterobacter, and the bacterial agent is sprayed onto a solid bacterial carrier for preservation. After sorting the catering waste, add the compound bacterial agent according to 0.1-8% of the total amount of garbage, turn it over every 0.5 hours, keep ventilation, and react for 24-48 hours at 25-40 degrees Celsius, which can reduce the waste. Volume 99% effect.

[0028] The invention constructs a strain combination reagent capable of efficiently degrading kitchen waste, so as to realize harmless treatment of kitchen waste in a short period of time. The present invention is characterized in that: a composite bacterial agent composed of strict aerobic bacteria and facultative anaerobic bacteria is constructed. The composite microbial agent uses aerobic fermentation as the main method to degrade food waste, and strictly aerobic bacteria undertake ...

Abstract

The invention discloses a compound bacterial agent for efficiently degrading kitchen waste and a preparation method thereof. The compound bacterial agent is prepared from pseudomonas, enterococcus andenterobacter, wherein the pseudomonas is aerobic bacteria, and both the enterococcus and the enterobacter are facultative anaerobic bacteria. Two types of facultative anaerobic bacteria are added asauxiliary components, wherein the enterococcus undertakes the main degradation work in the case of sufficient oxygen, and the enterobacter exerts the main degradation work in the micro-environment inthe case of local hypoxia, thereby making up for the functional defects caused by singly using aerobic bacteria, and greatly enhancing the waste treatment efficiency.

Description

technical field [0001] The invention relates to a composite bacterial agent and a manufacturing method thereof, in particular to a composite bacterial agent capable of efficiently degrading kitchen waste and a manufacturing method thereof. Background technique [0002] Food waste refers to waste and residues generated during food processing and eating. With the expansion of the city scale, the output of domestic waste has increased sharply, reaching more than 200 million tons per year at present, of which 37%-62% is kitchen waste. Food waste has a high water content and is rich in nutrients. It is easy to rot during storage and transportation, causing sour odor and affecting the urban sanitation environment. The spread of diseases and how to deal with food waste reasonably and efficiently will directly affect the development of cities and the quality of life. Traditional food waste disposal methods include feeding livestock, landfilling, incineration and composting. Becau...
