Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the existing microbial preparations have poor garbage degradation effect and the preparation of fermentation agent is tedious due to too many strains, and provide a kind of fermentation agent with high bacterial concentration and good swill degradation effect to degrade swill garbage. Microbial agents

Embodiment Construction

[0032] The technical contents of the present invention will be further described below in conjunction with the examples; the following examples are illustrative, not restrictive, and the protection scope of the present invention cannot be limited with the following examples.

[0033] The present invention isolates and obtains bacterial strains with relatively high amylase activity, protease activity, cellulase activity and lipase activity from compost soil samples, and studies the high-density cultivation process of each bacterial strain, through seed cultivation, fermentation cultivation, Spray-drying and other methods prepared the bacterial cell concentration at 1.0×10 11 Individual / g or more high-concentration microbial preparations. Then the bacterial powders of different strains were mixed according to the optimal ratio, and then the degradation experiment was carried out on a 1.5kg processor to observe the degradation effect.

[0034] The seven strains described in the ...

Abstract

The invention relates to the microorganism agent for degrading hogwash garbage and the preparation craft, which is formed by mixing seven active germ powders in certain matching. The seven germs are as following: Bacillus subtilis E4, H11, Bacillus licheniformis A2, I1, Bacillus cereus F3, F6 and Bacillus stearothermophilus H13. The invention resolves the problems of bad degrading result and complicated preparation of the hametz due to overfull germ sorts existing in the import microorganism agent degrading the oil component in the garbage, and adopts bacillocin as the strain to obtain the germ powder through the crafts of seed culturing, fermentation culturing and sponging drying. The invention has the advantages of small sorts of germ, simple fermenting process, high concentration of germ in the germ powder and good degrading result, and can achieve minimization treatment, innocent treatment and treatment of being turned into resources, therefore can not only improve the environment sanitary of the city, but also lay a solid foundation for large-scale commercial process. The invention also has an advantage of good economic benefit.

Description

technical field [0001] The invention belongs to the field of microorganisms, in particular to a microbial preparation for degrading swill waste and a preparation process thereof. Background technique [0002] Slop, that is leftovers, is a kind of domestic waste formed by residents in the process of living consumption. With the development of social economy and the improvement of people's living standards, the amount of slops is increasing. In Shanghai alone, the amount of slops has reached more than 1,300 tons every day, which has seriously affected urban environmental sanitation and people's health. [0003] At present, the treatment methods of slop waste mainly include: composting treatment, anaerobic fermentation treatment, vacuum frying technology, microbial and earthworm treatment, EATAD process (high temperature aerobic pollution-free biological treatment method) and aerobic bioreactor treatment method. Among them, the aerobic bioreactor treatment method is to put the...
