Abstract
The present invention provides a mixing strain for treating kitchen waste, and a method for carrying out a kitchen waste treatment by using the mixing strain. The mixing strain comprises Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus cereus, Bacillus megaterium, and Bacillus subtilis. According to the present invention, the strains are mixed with kitchen waste, a water spraying effect is adopted, fermentation decomposition is performed within a water content range of 50-95%, fermentation products are discharged in the form of aqueous solutions, and no solid residue is remained.
Description
Technical field
The present invention relates to a kind of method and mikrobe associate strain that utilizes biological degradation to handle rubbish from cooking; Relate in particular to a kind of method of handling the associate strain of rubbish from cooking and using said associate strain processing rubbish from cooking; Said bacterial classification and method are handled after the rubbish from cooking, not the residual solids residue.
Background technology
Catering trades such as rubbish from cooking (hogwash) general reference restaurant, hotel, and the food blanking and the food residues in canteens such as enterprises and institutions, universities and colleges.Along with the urban economy rapid growth, the rapid expansion of city size, rubbish from cooking grows with each passing day.The generation of China's rubbish from cooking every day surpasses 20Kt, it is reported ton surplus only the generating capacity of Shanghai City hogwash every day just reaches 1300.Because rubbish from cooking is fermented easily, rotten, rot, not only produce a large amount of toxin, distribute foul gas, go back polluted-water and atmosphere, have a strong impact on environmental health, to people's health formation potential threat.Thereby the severe pendulum of hogwash refuse treatment problem is in face of the people.
The traditional rubbish from cooking processing mode of China is directly to deliver to plant to feed live pig, and this kind processing mode exists multiple potential harm to environment, very easily causes transmission of disease.Bird flu in recent years, communicable diseases such as foot and mouth disease are popular on a large scale, and the cross infection between people and animals is to human beings'health, and society stable constituted great threat.At present, Shanghai, cities such as Suzhou have formulated relevant policies in succession, prohibite with hogwash and feed live pig.
The method of this type of countries in the world processing at present rubbish has usually: 1) landfill method: through refuse collection, be shipped to landfill yard and pave compacting.Its advantage is simple and easy to do.Shortcoming is polluted, and is taken a large amount of soils for causing underground water, air, surrounding environment.2) burning method: solid waste high temperature decomposes, the comprehensive treating process process of deep oxidation.Its advantage is eliminated unwanted bacteria for reducing the waste volume rapidly significantly, can also be used for the heat supply generating.Shortcoming is big for investment, to airborne release objectionable impurities ianthone such as dioxin etc.) and scatter bad dust, and generated energy is limited.3) compost: become harmless corruption behind the rubbish fermentation and plant matter, like the disclosed method that rubbish from cooking is converted into fertilizer of patent CN1858027A.But fermentation period is long, and nutrient content is low, and it is big to handle the back volume, is only applicable to ungetable rural area, is inappropriate for the bigger city of rubbish from cooking generation.
In general the rubbish from cooking waste material is abundant, and the contents of saccharide ratio is big, and hogwash is with protein; Starch and animal tallow class etc. are staple, and saliferous, and oil quantity is high; Be unfavorable for direct utilization; But organic content is high, has higher biodegradability, and this also provides feasible approach for the trans-utilization of hogwash.Present topmost transformation technology is a biotransformation method.Bio-transformation is the metabolism that utilizes mikrobe, realizes the stabilization of rubbish, and is innoxious, carries out the recycling of resource simultaneously.Wherein apparatus for disposing of food waste is to handle rubbish from cooking the best way at present, and hogwash and microbial strains are dropped in the special garbage disposer, utilizes multiple aerobic mikrobe that the organism in the hogwash is decomposed.It is low that this method has expense, obvious processing effect with can eliminate rubbish in advantages such as sources, therefore also be one of problem of popular research both at home and abroad in recent years.
The research of Japan aspect biological degradation hogwash rubbish is more successful, and the hogwash handler is in big area popularization in Japan.China also has company to introduce this type handler of Japan; But microbial strains then can only dependence on import, and the microbial strains of Japan is relatively poor to the degradation effect of oils composition in the rubbish, and some fibre-bearing food with high residues can not well be degraded; The diet formula of China has determined that the oils composition is higher in the hogwash rubbish of China; Therefore, the microbial strains of import is when handling domestic hogwash rubbish, and effect is unsatisfactory.
In recent years; China also has some enterprise self-determinings to research and develop microbial strains and the method for handling rubbish from cooking; Microbial preparation like the disclosed degraded hogwash of treatment process, the patent CN101173232A rubbish of the disclosed high concentration swill of patent CN100375723C; Solved the handling problem of rubbish from cooking to a certain extent, but the inferior position of aspect such as its reduction rate is low, the treatment time is long, ambient temperature range is little has also limited its development.
Also having company to choose anaerobion degrades; In the experiment of laboratory lab scale; This bacterial classification has higher degradation rate, but in suitability for industrialized production and practical application, is difficult to reach the anaerobism requirement, so anaerobion is not suitable for present refuse biochemical treatment facility.
At present, still there is following deficiency in the prior art of utilizing biological degradation to handle rubbish from cooking that can industrial application:
1) can not efficient degradation fibre-bearing food with high residue.The high residues of fibre-bearing such as the wild rice stem in the rubbish from cooking, bamboo shoot shell if can not in time degrade, often are deposited on and handle in the trough operation that then hinders whipping device of long duration.
2). the grease in the rubbish from cooking can not effectively be degraded.China's diet formula has determined that grease is high in the hogwash, and grease can not get good degraded then makes matrix be sticked together, and after operation for some time, the matrix in the trough just can be lumpd, and influences the normal operation of machine.
3) degradation time is long, and degradation rate is low.In the daily life, have every day a large amount of new hogwash to produce, if can not be degraded timely and effectively, hogwash is accumulated in to be handled in the trough, the load that then exceeds handler of long duration, and severe patient loses the use of machine.
In sum, the present treatment process of rubbish from cooking still can the lingering section residue, is unfavorable for the work of treatment facility, and residual residue also needs further to handle simultaneously, therefore, still needs mikrobe associate strain, preparation and the method for new processing rubbish from cooking.
