Abstract

The invention discloses a composite microbial deodorizer and a preparation method thereof. According to the invention, thiobacillus ferrooxidans, rhizobium sludge, bacillus amyloliquefaciens, rhodopseudomonas palustris, pseudomonas stutzeri, bacillus coagulans and hansenula polymorpha are selected for use; liquid fermentation is performed respectively, and then compounding is performed in proportion; then linalool is added in proportion and the substances are fully mixed to prepare a composite microbial deodorizer capable of effectively expelling flies and insects, inhibiting growth and propagation of harmful flora and reducing and removing foul gas in the environment. The thiobacillus ferrooxidans (CFU / g) in the product is greater than or equal to 2.95*10<8>; the rhizobium sludge (CFU / g)is greater than or equal to 1.05*10<8>; the bacillus amyloliquefaciens (CFU / g) is greater than or equal to 1.73*10<8>; the rhodopseudomonas palustris (CFU / g) is larger than or equal to 2.55*10<8>; thepseudomonas stutzeri (CFU / g) is larger than or equal to 1.15*10<8>; the bacillus coagulans (CFU / g) is larger than or equal to 2.86*10<8>; the hansenula anomala (CFU / g) is larger than or equal to 2.97*10<8>; and the total amount of organic acids is larger than or equal to 25.8 g / L. The product provided by the invention has an obvious deodorization effect, the NH3 removal rate is greater than or equal to 78.14%, the H2S removal rate is greater than or equal to 71.64%, the odor concentration elimination rate is greater than or equal to 84.95%, and the mosquito and fly expelling rate is greater than or equal to 74.16%.

Description

Technical field: [0001] The invention relates to the technical field of environmental bioengineering, in particular to a compound microbial deodorant and a preparation method thereof. Background technique: [0002] With the rapid development of social economy and the continuous acceleration of urbanization, the problem of indoor and outdoor environmental pollution has become increasingly prominent. As one of the environmental hazards, stench and bacteria breeding in the environment directly affect people's quality of life and even endanger people's health, which has attracted more and more people's attention. [0003] At present, there are more than 4,000 kinds of odorous substances perceived by human sense of smell, which can be divided into domestic sources and industrial sources according to the source of production. The source of life refers to the stench produced in daily life, such as household toilets, public toilets, sewage treatment plants, garbage transfer station...
