Problems solved by technology

[0003] Although there are many methods of using microbial agents for garbage disposal, few of them are actually applied.
And it can’t solve the problem of high humidity and odor. Most of the fungicides are in the small test stage of the laboratory, and the effect is very poor when applied on a large scale. It needs to be pre-treated by heating and removing the moisture in the garbage.
So far, no microbial treatment technology has been found to treat food waste below 45°C and without filtering to remove water.

Embodiment 1

[0020] This example is the preparation of compound microbial bacterial agent.

[0021] (1) Preparation of composite bacteria

[0022] 1) Cultivation of protein degrading bacteria

[0023] The protein-degrading bacteria used in this example is the strain numbered HJK6.2-2 preserved by the Guangdong Provincial Microorganism Preservation and Management Center. It was transferred from the slant medium to a 10ml liquid test tube for shaking culture, and gradually enlarged to a 3L fermenter. Cultivate in functional medium, culture temperature is 30-37°C, culture time is 12-24h, the best is 16-18h. Then the cells were collected by centrifugation.

[0024] The functional medium used was soluble starch 20g, potassium nitrate 1g, sodium chloride 0.5g, K 2 HPO 4 ·3H 2 O0.5g, MgSO 4 ·7H 2 O0.5g, FeSO 4 ·7H 2 O0.01g, 20g agar, 1000ml water, pH7.2~7.4. When preparing, first use cold water to make the starch into a paste, pour it into boiling water, heat it on the fire, add other i...

Embodiment 2

[0043] This example is the preparation of compound microbial bacterial agent.

[0044] (1) Preparation of composite bacteria

[0045] According to the culture method of Example 1, each strain was cultured separately, and then centrifuged to collect the thalline, and mixed according to the following ratio to prepare a composite thallus, protein degrading bacteria: starch degrading bacteria: sugar degrading bacteria: fat degrading bacteria: cellulose degrading bacteria =1.5:1:1.5:1.5:1.5.

[0046] (2) Preparation of carrier materials

[0047] Cinder, zeolite, wood shavings, buckwheat husk, bran, and activated carbon are mixed in the following parts by mass to make carrier material, cinder: zeolite: wood shavings: buckwheat husk: bran: activated carbon=1: 1: 0.5: 0.5: 0.5: 0.05

[0048] (3) Preparation of composite microbial bacterial agent

[0049]The composite microbial bacterial agent is prepared by mixing the composite bacterium with the carrier material, and the composit...

Embodiment 3

[0051] This example is the test of the degradation rate of kitchen waste with the microbial inoculant (powder) prepared in Example 1.

[0052] 1. Composition of kitchen waste:

[0053] For the remaining meals in the cafeteria, remove large and hard parts such as bones.

[0054] 2. Put the composite microbial bacterial agent prepared in Example 1 into a garbage machine, continue to ferment for 24 hours, and then add 1kg of garbage. The mixing ratio of kitchen waste and microbial agent is about 1:6.0.

[0055] 3. Determination of garbage degradation rate:

[0056] Weigh the weight of the garbage machine and the bacterial agent when no garbage is added, and it is 21.07kg. After adding 1kg of food waste every other day, the total weight of the garbage machine, the bacterial agent and the remaining garbage is weighed 10 days later to be 23.15kg. According to the formula of weight average reduction efficiency

[0057]

[0058] B=21.07+1×10=31.07, C=23.15, A=1×10=10

Abstract

The invention discloses a high-efficient restaurant-kitchen waste degrading microorganism bacterial agent and a preparation method and application thereof. The microorganism bacterial agent is prepared by mixing microorganism compound thalli for degrading restaurant-kitchen wastes and carrier materials with high air permeability, and the compound thalli accounts for 5 to 20 percent based on the total mass of the carrier materials. The compound microorganism bacterial agent of the invention can achieve good effect when used in a waste grinder, and the average degradation rate is over 77 percent every day. The microorganism bacterial agent fundamentally solves the problems that the restaurant-kitchen wastes have high humidity and strong peculiar smell, and high-salt and high-oil components are difficultly degraded existing in the prior art. The microorganism bacterial agent has the advantages of stable treating effect, simple preparation method and no environmental pollution.

Description

technical field [0001] The invention relates to the technical field of microbial bacterial agents, in particular to a preparation method and application of a composite bacterial agent, which belongs to the environmental protection field of garbage harmlessness, reduction and resource utilization, and specifically relates to a method for efficiently degrading kitchen waste Preparation and application of microbial agents. 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%-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 atmo...
