Problems solved by technology

[0004] The effects of existing deodorant bacteria agents are uneven, the strains of bacteria agents are single, and the pertinence is not strong. There is no specific high-efficiency deodorizer bacteria agent for the deodorization of domestic garbage. Therefore, in view of the above problems, in In terms of domestic waste deodorization, there is an urgent need for a microbial agent that can improve the ecological environment of waste, inhibit the growth of harmful microorganisms, and eliminate the production of malodorous gases

Embodiment

[0013] 1. Selection of deodorizing strains Consult relevant literature, select multiple strains of bacteria, actinomycetes, molds and yeasts with deodorizing effects, and then inoculate each strain on the culture medium in pairs by cross experiment to verify whether there are Antagonism, finally select 7 strains that do not have antagonism: Bacillus licheniformis, Bacillus subtilis, Bacillus natto, Candida utilis, Saccharomyces spp., Thermomonospora chromogenicum and Aspergillus oryzae.

[0014] 2. Preparation of single bacterial agent powder

[0015] (1) Preparation of Bacteria, Actinomycetes, and Saccharomyces

[0016] a. Take one loop of the activated strain on the plate, inoculate it into 250ml of the corresponding liquid medium, put it in a full-temperature shaker cabinet, at the optimum temperature (37°C for bacteria, 45°C for actinomycetes, and 28°C for yeast), Cultivate at 120r / min for 12-36h (12h for bacteria, 36h for actinomycetes, 24h for yeast) until entering the ...

Abstract

The invention relates to preparation and application of a household garbage deodorizing microorganism environmental degerming agent. The household garbage deodorizing microorganism environmental degerming agent mainly comprises bacillus licheniformis, bacillus subtilis, bacillus natto, candida utilis, sporobolomyces, chromogenic thermomonospoaceae and aspergillus oryzae. According to the preparation method of the household garbage deodorizing microorganism environmental degerming agent, bacteria, molds, yeasts and actinomycetes are cultivated in different manners, and through liquid culture and solid culture, are crushed and mixed in proportion to produce the household garbage deodorizing microorganism environmental degerming agent. When added into household garbage at a certain proportion, the household garbage deodorizing microorganism environmental degerming agent can absorb odorous gases such as hydrogen sulfide and ammonia generated during degradation of household garbage to eliminate the odor of the household garbage and leakage liquid, thereby inhibiting growth of putrefying bacteria, promoting decomposition of the household garbage and fundamentally eliminating odors, and during the process, the average removal rate of NH3 is 97.85%, the average removal rate of H2S is 98.12%, the average removal rate of odor concentration is 90.12%, and the average removal rate of other microorganism.

Description

technical field [0001] The invention belongs to the field of environmental protection, and relates to a preparation method and application of a microbial environmental protection bacterial agent used for deodorization of domestic garbage Background technique [0002] With the development of social economy and the enhancement of people's awareness of environmental protection, the requirements for environmental quality are getting higher and higher. With the increase in population and the acceleration of urbanization, the amount of urban domestic garbage is increasing day by day, and the ensuing environmental problems caused by garbage collection points and garbage disposal sites in urban centers have become increasingly prominent. It will seriously affect and endanger the ecological environment, and will also cause unhappiness and disgust to nearby residents, and endanger people's health. Therefore, if eliminating the stench that effectively and safely removes house refuse t...
