Biological agent for processing glutamic acid fermentation waste water

Abstract

The invention relates to biological agent for processing glutamic acid fermentation waste water. Mycoprotein is separated from glutamic acid fermentation liquid through a high-speed disc separator, bacteria removing liquid is gathered, the mycoprotein is precipitated, compound seed liquid is added to the mycoprotein for preparing probiotics, the waste water generated by extracting glutamic acid from the bacteria removing liquid is drained into a sewage processing system, compound microorganism bacterium agent is added to the waste water to perform advanced treatment, and the waste water is discharged after reaching the standard. The biological agent for processing glutamic acid fermentation waste water is economical and environmental friendly and has broad application prospect.

Description

technical field

[0001] The invention relates to the field of glutamic acid extraction technology in the biological fermentation industry, and specifically provides a biological preparation for treating glutamic acid fermentation wastewater. Background technique

[0002] With the rapid development of the economy and the continuous improvement of technology, my country has become a major producer and consumer of monosodium glutamate, but the amount of wastewater discharged during the production of monosodium glutamate is large, and the mother liquor discharged from the monosodium glutamate fermentation broth after isoelectric extraction of glutamic acid has CODCr High, high BOD5, high bacteria content, high sulfate radical (chloride ion before pH adjustment with sulfuric acid) content, high ammonia nitrogen content and low pH value (1.5-3.2) are characterized by "five highs and one low". It is a kind of industrial wastewater that is very difficult to treat. Due to the ineffec...
