Compound microbial agent and preparation method thereof

Abstract

The invention discloses a compound microbial agent which comprises a main strain and one of an air purification strain, a water quality purification strain and a soil improvement strain, and the main strain comprises photosynthetic bacteria, saccharomycetes, lactic acid bacteria, actinomycetes and bacillus; the air purification strains comprise neosphingolipid, acidithiobacillus thiooxidans, thiobacillus denitrificans, rhodococcus purpureus, comamonas testosteroni and pseudomonas; the water quality purification strains comprise nitrifying bacteria, aerobiotic denitrifying bacteria, aeromycete, rhodobacter sphaeroides, bacillus subtilis, bifidobacterium longum and pseudomonas testosteroni; the soil improvement strains comprise nitrogen-fixing pantoea, azotobacter chroococcum, rhizobium, nitrosomonas, thermomonas and alcaligenes. The compound microbial agent disclosed by the invention can inhibit various bacteria, can degrade harmful substances, and has an obvious use effect.

Description

technical field [0001] The invention relates to the technical field of composite microbial strains, in particular to a composite microbial bacterial agent and a preparation method thereof. Background technique [0002] With the acceleration of my country's urbanization process, the urban population is increasing day by day, followed by the rapid increase of urban domestic waste. According to incomplete statistics, in recent years, the annual growth rate of my country's waste has reached more than 10%, and nearly 150 million tons of waste are generated every year. , at present, domestic municipal solid waste has accumulated as much as 7 billion tons, of which 80% to 90% come from large and medium-sized cities, but the treatment rate is only about 50%, and two-thirds of the more than 600 cities in the country Mid-sized cities are surrounded by domestic waste. At present, my country's urban domestic waste is dominated by "end-of-life treatment", mainly using landfill, incineratio...

Problems solved by technology

[0002] With the acceleration of my country's urbanization process, the urban population is increasing day by day, followed by the rapid increase of urban domestic waste. According to incomplete statistics, in recent years, the annual growth rate of my country's waste has reached more than 10%, and nearly 150 million tons of waste are generated every year. , at present, domestic municipal solid waste has accumulated as much as 7 billion tons, of which 80% to 90% come from large and medium-sized cities, but the treatment rate is only about 50%, and two-thirds of the more than 600 cities in the country Mid-sized cities are surrounded by domestic waste. At present, my country's urban domestic waste is dominated by "end-of-life treatment", mainly using landfill, incineration and composting. A large amount of malodorous gas is produced, which seriously plagues the daily life and health of residents. Gas chromatography detection shows that the main component of municipal solid waste odor is ammonia gas

[0003] Microbial deodorization technology uses the physiological metabolic activities of microorganisms to degrade odorous substances to achieve the purpose of deodorization. Compared with other deodorization methods, microbial deodorization method has investment less, low processing cost, simple maintenance and management, convenient operation, etc.; the existing general compound microbial deodorant also has poor coexistence of various strains, poor strain stability, poor effect of degrading hydrogen sulfide and ammonia, and cannot inhibit other The growth of miscellaneous bacteria has limited the further application of compound microbial deodorant
