The invention discloses a method for fermenting and producing a
microbial agent by utilizing cassava
alcohol residues, belonging to the technical field of
microbial agent production, so that the high-quality
microbial agent is produced, and meanwhile, the
pollution caused by the cassava
alcohol residues also can be treated, and the cyclic economy benefit for the cassava
alcohol industry is realized. The method for fermenting and producing the microbial agent by utilizing the cassava alcohol residues comprises the following steps of: mixing the cassava alcohol residues,
humic acid decomposed
coal or grass carbon and dry
straw ash, wherein the
water content of the mixture is controlled to be 33%-70%; adding the microbial agent being 2% of the
mass of the mixture into the mixture, stirring uniformly and quickly, packing the mixture into a seal bag, carrying out anaerobic
fermentation for 10 days at the normal temperature in the southern of China, thereby producing the microbial agent with the number of effective viable
bacteria greater than or equal to 0.3billion /
gram (higher than the
national standard by 0.2 billion /
gram). According to the method, the cost is low; the operation is simple; the product quality is high; the cassava alcohol residues are changed into wealth from waste, and effective
resource utilization is realized; not only is the environment
pollution problem solved, but also high environment-friendly expanse is saved for cassava alcohol enterprises, and meanwhile good economic benefit is brought; an enclosed biological circle of the cassava
alcohol production is formed; and the cyclic economy benefit is created.
