Method of producing composite and highly effective microorganism preparation for waste water treatment

Abstract

This invention relates to a preparation method for a compound high efficient microbe preparation used in processing waste water including: A, selecting and cultivating, B, fermenting and cultivating the preparation of oxygen and anaerobic compound microbes, C, fermenting and cultivating the preparation of aerobic microbes, D, mixing them. 1, the preparation prepared in this invention is avirulent and will not cause second time pollution, 2, microbes in this preparation can degradate organics and ammonia nitrogen pollutant factors thoroughly due to multikind of microbes and quick speed to degradate pollutants in waste water, 3, output of mud is less, the life time is long and its settlement is good, 4, the preparation method is simple.

Description

technical field [0001] The invention relates to a preparation method of a microbial preparation, in particular to a preparation method of a composite high-efficiency microbial preparation for wastewater treatment; it belongs to the field of environmental protection. Background technique [0002] With the continuous development of human society and the continuous improvement of productivity, the pollution of human production and life to the environment is also increasing. A large amount of unqualified sewage is discharged into the environment, exacerbating the shortage of water resources. Microbial treatment technology is the most effective and economical method to treat sewage. However, the existing microbial treatment system in the industry mainly considers the optimization of processes such as contact oxidation, UASB, oxidation ditch, biological filter, etc., while ignoring the microorganisms as the main body of treatment. Most of these processes are used under natural co...

Problems solved by technology

Compared with wild microorganisms, the activity of the compound microorganisms made by this method has been greatly improved, but this method only adopts special medium to domesticate and cultivate the microorganisms; the activity of microorganisms is still low, and the microorganisms made by this method are mainly Microorganisms that degrade lignin and cellulose can only be used to treat wastewater produced by papermaking, but have no treatment function for other wastewater containing a large amount of complex organic matter and ammonia nitrogen; therefore, the wastewater treatment is not thorough and cannot meet the needs of large-scale production; People cultivate a variety of microorganisms later on, and make a compound preparation composed of a variety of microorganisms, such as a Chinese patent application (01127096.9) a compound microbial bacterial agent and its production method, the method adopts the method of colonizing mainly photosynthetic bacteria , lactic acid bacteria, actinomycetes, filamentous bacteria of the fermentation system and other composite microbial strains are cultivated and multiplied to form a composite microbial bacterial agent. The composite microorganisms made by this method are effective for organic wastewater However, this method adopts the method of ordinary multiplication and cultivation, which does not activate the activity of microorganisms, and the types of microorganisms are relatively single, which cannot form a relatively complete food chain, so it cannot achieve a good treatment effect.
