Pretreatment method before biochemical treatment of fermentation mother liquor

Abstract

The invention provides a pretreatment method before biochemical treatment of fermentation mother liquor. In the method, two high-temperature sterilizations are carried out on the fermentation mother liquor through waste gas and waste residues generated by an industrial boiler, and meanwhile, organic matters contained in the fermentation mother liquor are precipitated and adsorbed by directly utilizing the waste residues. The treated fermentation mother liquor is precipitated, and the fermentation mother liquor can be directly drained into an environment-friendly pool and subjected to biochemical treatment, which can not only meet the requirement of industrialized mass production, but also can reduce pollutions, the energy consumption, the investment cost of equipment and the occupation area of workshops.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a pretreatment method of fermented yeast liquid before biochemical treatment. Background technique [0002] In industrial production, when bio-fermentation method is used to make pharmaceuticals, if the residual fermented yeast liquid after extraction and separation is directly discharged, it will have a serious impact on the environment. Therefore, for a long time, the treatment of biological fermentation yeast liquid has been using traditional methods such as incineration, deep burial, and powder spraying and drying. However, incineration and deep burial will cause air and water pollution, while powder spraying drying has high costs, high energy consumption, high treatment costs, and a small daily treatment volume of mother liquor, making it difficult to meet the requirements of large-scale production. [0003] In addition, the biological fermentation yeast liq...

Problems solved by technology

However, incineration and deep burial will cause air and water pollution, while powder spraying drying has high costs, high energy consumption, high treatment costs, and small daily treatment of mother liquor, which is difficult to meet the requirements of large-scale production

[0003] In addition, the biological fermentation yeast liquid contains mycelium, which is a kind of filamentous bacteria, and the increase of filamentous bacteria can inhibit the growth of useful microorganisms in biochemical treatment of sewage, thereby reducing the removal rate of sewage COD, so it cannot Discharge the fermented yeast liquid directly into the environmental protection sewage pool for biochemical treatment
