Compound microorganism preparation, preparing method and application of compound microorganism preparation to processing animal carcasses

Abstract

The invention discloses a compound microorganism preparation. The compound microorganism preparation comprises thermophilic fat bacillus, pseudomonas aeruginosa, streptococcus thermophilus, bacillus megatherium and bacillus flexus. The invention further discloses a preparing method of the compound microorganism preparation and application of the compound microorganism preparation to processing animal carcasses. Compared with the prior art, the compound microorganism preparation has the beneficial effects that macromolecular compounds, such as fat and celluloses in the animal carcasses and straw auxiliary materials, which are difficult to decompose can be efficiently and rapidly decomposed through the compound microorganism preparation, and the animal carcasses are converted into organic fertilizers with the low fat content; and the compound microorganism preparation further has the efficient deodorization function, the release amount of NH3 and H2S in the processing procedure can be effectively reduced, the stink concentration is reduced, and odorless processing is achieved. Finally, the animal carcasses are efficiently and safely processed into the organic fertilizers in an environmental protection manner, and resource utilization of the animal carcasses is achieved.

Description

technical field [0001] The invention relates to the technical field of microbial environmental protection, in particular to a compound microbial preparation, a preparation method and an application in treating animal corpses. Background technique [0002] With the continuous expansion of the breeding industry, animals in large-scale animal breeding factories are susceptible to various epidemic diseases, which can easily lead to large-scale death of animals. It may flow into the market, cause food safety problems, and seriously threaten people's health. How to properly dispose of dead animal carcasses has become an urgent problem to be solved. [0003] According to the "Pilot Program for Establishing a Long-term Mechanism for the Harmless Treatment of Sick and Dead Pigs" issued by the Ministry of Agriculture in 2013, the methods for the harmless treatment of sick and dead pigs mainly include deep burial, incineration, high temperature and high pressure production, and biologi...

Problems solved by technology

[0005]The above-mentioned technologies all belong to the traditional biological fermentation method. The animal carcass and straw auxiliary materials are mixed, cut, minced and then added with a compound microbial preparation. This method can make the animal carcass have been effectively treated, but there are still some problems in the current compound microbial preparations: first, a large amount of NH3 and H2S and other malodorous gases pollute the surrounding environment; secondly, the use of current compound microbial preparations to treat animal carcasses cannot effectively degrade the fat in animal carcasses, and the organic fertilizers produced have high oil content, which is not conducive to crops If the fertilizer is applied to the paddy field, a layer of water film will be formed on the water surface, causing the root system of the plant to rot due to anoxic
