Compound microbial agent solid particle product for environment protection and preparation method thereof

Abstract

The invention relates to the technical field of biological fermentation and in particular relates to a compound microbial agent solid particle product for environment protection and a preparation method thereof. The method comprises the following steps: (1) carrying out high-density fermentation culture on a compound microorganism for the environment protection, so as to obtain a high-density fermentation solution; adjusting the solid content of microorganisms in the high-density fermentation solution; (2) adding a drying protection agent into the adjusted high-density fermentation solution, wherein the adding amount of the drying protection agent is 0.1 to 10 percent of the weight of the adjusted high-density fermentation solution; uniformly mixing to obtain bacterial vaccine; (3) mixingthe bacterial vaccine and auxiliary materials and granulating to obtain solid particles; (4) drying the solid particles at 25 to 80 DEG C to obtain the compound microbial agent solid particle productfor the environment protection, wherein the drying time is 8 to 48h. According to the preparation method provided by the invention, raw materials are low in price, technological operation is simple and the production efficiency is high; the economical and efficient compound microbial agent solid particle product is provided for the environment protection industry.

Description

Technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a composite microbial inoculum solid particle product for environmental protection and a preparation method thereof. Background technique [0002] With the rapid development of my country’s industry, environmental pollution has become more and more serious, and environmental pollution control has become more and more difficult. Traditional physical and chemical treatments are difficult to meet the discharge standards. The application of targeted microbial agents to control environmental pollution has a good effect and operation People are paying more and more attention to stability, and the use of environmentally friendly microbial agents is also increasing year by year. [0003] Existing environmentally-friendly microbial inoculants usually have great production limitations, which are mainly manifested as: low mechanization in the production process, difficult to achieve...

AI Technical Summary

Problems solved by technology

[0003] Existing environmentally friendly microbial agent products usually have great production limitations, mainly as follows: the degree of mechanization in the production process is low, and it is difficult to achieve process control; the fermentation cycle is long and the output is low; due to limited conditions, it is not suitable for large-scale production; Due to incomplete sterilization, there is often contamination by miscellaneous bacteria, which affects the efficacy of the product, making the efficacy unstable or not obvious, or even ineffective, and the current environmental protection microbial agent products are mainly liquid products, the product performance is unstable, the shelf life is short, and transportation is difficult. Inconvenient, thus affecting its application
