Problems solved by technology

[0004] However, there are still some problems in the use of biological methods to treat kitchen waste. For example, the treatment efficiency is low. Most of the microorganisms used in the existing kitchen waste treatment are common microbial agents. Long period, low treatment efficiency, and long time-consuming; high treatment cost, the existing kitchen waste treatment cost is high, mainly in the cost of microbial agents, auxiliary material additives, site costs, operating costs, etc.; in addition, In the process of processing kitchen waste, it is necessary to carry out pretreatment processes such as heating to remove moisture in the waste, which increases the process flow and energy consumption

Embodiment 1

[0067] This embodiment provides a composite microbial degradation bacterial agent for kitchen waste treatment, including:

[0068] The effective number of viable bacteria is 3×10 9 16 parts by weight of Bacillus subtilis subsp. cfu / mL, effective viable count is 3×10 8 cfu / mL 5 parts by weight of Bacillus halotolerant, the effective number of viable bacteria is 1×10 9 cfu / mL Bacillus amyloliquefaciens 14 parts by weight, the effective number of viable bacteria is 1×10 9 8 parts by weight of Bacillus cereus in cfu / mL, the number of effective viable bacteria is 3×10 9 7 parts by weight of Bacillus thuringiensis cfu / mL, 250 parts by weight of 4-amino-2-nitrodiphenylamine-4-sulfonic acid modified straw, 100 parts by weight of nano-hydroxyapatite, 64 parts by weight of peptone, L-preserved 26 parts by weight of amino acid, 10 parts by weight of potassium fulvic acid;

[0069] The composite microbial degradation bacterial agent is specifically prepared by the following method:

...

Embodiment 2

[0086] This example provides another compound microbial degradation bacterial agent for kitchen waste treatment. Its components and preparation method are basically the same as in Example 1, except that in this example, unmodified straw is used instead of 4- Amino-2-nitrodiphenylamine-4-sulfonic acid modified straw as carrier.

Embodiment 3

[0088] This example provides another compound microbial degradation bacterial agent for kitchen waste treatment. Its components and preparation method are basically the same as in Example 1, except that in this example, the carrier is only 4-amino-2-nitrate Diphenylamine-4-sulfonic acid modified straw.

Abstract

The invention belongs to the field of biotechnology, and in particular relates to a composite microbial degradation bacterial agent for kitchen waste treatment, a preparation method and an application thereof. The present invention uses Bacillus subtilis subsp. subsp. subtilis, Bacillus halotolerant, Bacillus amyloliquefaciens, Bacillus cereus and Bacillus thuringiensis as composite cells, and 4-amino-2-nitrodiphenylamine-4-sulfonic acid modified Straw and nano-hydroxyapatite are used as carriers, and peptone, L-proline, and potassium fulvic acid are added as auxiliary materials to obtain a composite microbial degradation bacterial agent for kitchen waste treatment. The bacteria have high activity, fast organic matter degradation rate, and carrier ratio The surface area is large, and the bacteria load is high, which can protect the bacteria to maintain a high activity at all times, and the excipients can improve the activity of the bacteria; the mutual cooperation and interaction between the composite bacteria, the carrier and the excipients make the composite microbial degradation bacteria agent can be in the environment. Under normal temperature, it can quickly and efficiently degrade the organic matter in the garbage, and the treatment effect is good.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to a composite microbial degradation bacterial agent for kitchen waste treatment, a preparation method and an application thereof. Background technique [0002] Kitchen waste refers to the dining waste produced by unit canteens, hotels, restaurants, etc., and the waste of discarded vegetables and fruits, discarded meat, fish and shrimp, leftovers and other waste produced by residents' households, which is the most abundant component of urban biomass waste. , is also the main component of environmental pollution and ecological risk caused by perishable deterioration. With the development of my country's economy and the acceleration of urbanization, the discharge of urban domestic waste is increasing. Kitchen waste has seriously affected our environment. Live healthy. [0003] Kitchen waste is an important part of organic waste in urban solid waste. Its phys...
