Problems solved by technology

[0003] Although there are many methods of using microbial agents for garbage disposal, they are rarely used, and the problems of high humidity and odor cannot be solved, and most of the agents are in the small test stage of the laboratory, and the effect is poor when applied on a large scale. Pre-treatment processes such as heating to remove moisture in the garbage are required
At present, no microbial treatment technology has been found to degrade food waste at room temperature and without filtering to remove water

Embodiment 1

[0022] Example 1 A Composite Microbial Agent for Degrading Kitchen Waste at Normal Temperature

[0023] The preparation method is:

[0024] (1) Cultivate bacterial strains and prepare composite bacteria

[0025] First, the lyophilized powder of the strain Lactobacillus acidophilus zsq11 was added to a 5mL liquid medium for shaking-table culture, and gradually enlarged to a 100L fermenter functional medium for culture. Cultivate in a fermenter at 28-38°C for 12-24 hours, preferably 16-20 hours, and then collect the cells by centrifugation. The composition of liquid medium and functional medium are: potassium nitrate 1g, sodium chloride 0.5g, yeast extract 0.5g, FeSO 4 ·7H 2 O 0.01g, pH7.2~7.4, when preparing, add water to 1000ml.

[0026] Firstly, the freeze-dried powder of the strain yeast Saccharomyces sp.zsq13 was added to 5ml liquid medium for shaking-table culture, and gradually enlarged to 100L fermenter functional medium for culture. Cultivate in a fermenter at 28-3...

Embodiment 2

[0038] Example 2 A Composite Microbial Agent for Degrading Kitchen Waste at Normal Temperature

[0039] The preparation method of the composite microbial bacterial agent of this embodiment is except that the weight ratio of the Lactobacillus acidophilus zsq11 thallus and the yeast Saccharomyces sp.zsq13 thallus obtained by centrifugation in step (1) is 1.5: 1; Broken peanut shells: sand: shavings: bran=2: 1.5: 0.8: 2; in step (3), except that the mass percentage of the compound thallus accounting for the compound microbial inoculum is 6%, other steps are all the same as in the examples 1 is the same.

[0040] The composite microbial bacterial agent of embodiment 2 is to the degradation rate test of kitchen waste:

[0041] (1) The composition of kitchen waste: the leftover meals in the canteen, remove the large and hard parts such as bones;

[0042] (2) Put the compound microbial bacterial agent that embodiment 1 makes into garbage machine, after continuing to ferment for 24h...

Embodiment 3

[0048] Example 3 A Composite Microbial Agent for Degrading Kitchen Waste at Normal Temperature

[0049] The preparation method of the composite microbial bacterial agent of this embodiment is except that the weight ratio of the Lactobacillus acidophilus zsq11 thallus and the yeast Saccharomyces sp.zsq13 thallus that centrifuges in the step (1) is 2: 3; Broken peanut shells: sand: wood shavings: bran=2.5: 1: 1: 2; in step (3), except that the mass percentage of the compound thallus accounting for the compound microbial bacterial agent is 8%, other steps are all the same as those in the examples 1 is the same.

[0050] The composite microbial bacterial agent of embodiment 3 is to the degradation rate test of kitchen waste:

[0051] (1) The composition of kitchen waste: the leftover meals in the canteen, remove the large and hard parts such as bones;

[0052] (2) Put the compound microbial bacterial agent that embodiment 1 makes into garbage machine, after continuing to ferment...

Abstract

The invention discloses a composite microbial agent capable of degrading kitchen waste at normal temperature, its preparation method and its application, the composite microbial agent is composed of composite thalline and carriers. The composite thalline is composed of lactobacillus acidophilus zsq11 and microzyme Saccharomyces sp. zsp13; the carriers are composed of crushed peanut shells, sands, wood chips and wheat brans. The composite thalline accounts for 5-10% of composite microbial agent by weight percentage. According to the invention, high efficiency complex bacterium and carrier materials with good permeability are mixed to prepare the composite microbial agent, the composite microbial agent is placed in the kitchen waste for treating and acquires good operation effect at normal temperature, the degradation rate of the kitchen waste can reach more than 75%, so that high temperature required in the prior art can be solved. The microbiological treatment processes such as moisture filtering and the like can be omitted. The invention has the advantages of simple processing step, stable effect and no environmental pollution.

Description

technical field [0001] The invention relates to the technical field of microbial bacterial agents, in particular, the invention relates to a composite microbial bacterial agent for efficiently degrading kitchen waste at room temperature and its preparation method and application. Background technique [0002] With the development of my country's economy and the acceleration of urbanization process, the population gathering and urbanization process will be accelerated, and the discharge of municipal solid waste is increasing. 37% to 62%. Since food waste contains a lot of sugar, starch, protein, and high salt and oil content, if it is not treated, food waste is easy to deteriorate, rot, ferment, breed harmful microorganisms and mosquitoes, and produce a lot of toxins and Distributing foul-smelling gas, polluting water bodies and the atmosphere, will seriously affect the appearance of the city, damage the health of residents, and destroy the quality of the environment. Howeve...
