Problems solved by technology

Activated carbon is widely used as an important adsorbent material because of its rich pore structure and huge specific surface area, good chemical stability and strong adsorption capacity, but its cost is high
There are also non-metallic ionic minerals such as attapulgite for adsorption, but natural non-metallic minerals have the following limitations as adsorbents: natural non-metallic minerals have high density and limited specific surface area, and the surface of natural non-metallic minerals is mostly negatively charged. And directly using natural non-metallic powder ore such as clay minerals as the adsorbent will have the problem of difficult separation of solid and liquid after adsorption
However, at present, there is no mature complete set of technology applied to production practice at home and abroad.
The main problem is that the one-time investment is too large, or the daily operation cost is too high, which cannot be afforded by most monosodium glutamate factories, and they have to maintain the status quo of excessive emissions for a long time

Description

technical field [0001] The invention relates to a waste water treatment preparation, in particular to a biochemical preparation for treating glutamic acid fermentation sewage. Background technique [0002] The chemical name of sodium glutamate is monosodium α-aminoglutarate, which is a salt formed by sodium ions and glutamate ions, in which glutamic acid is an amino acid and sodium is a metal element. The main ingredient of seasoning MSG commonly used in life is sodium glutamate. Monosodium glutamate is a commonly used flavoring agent in daily life, which can increase the umami taste of food and help improve the digestibility of food by the human body. In addition, glutamic acid has very important functions and is widely used in food, medicine, industry and agriculture. [0003] The main sources of glutamic acid fermentation sewage are: the waste mother liquor or ion exchange tail liquid after extracting glutamic acid from the fermentation broth; various equipment in the p...
