Problems solved by technology

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, most manufacturers cannot bear it, and have to maintain the status quo of excessive emissions for a long time
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

Abstract

The invention relates to a method for preparing biochemical preparations for treating threonine fermentation wastewater. The method includes preparing physical adsorbents and complex microbial inoculants. The complex microbial inoculants comprise, by volume, 6-7 parts of yeast, 5-6 parts of arthrobacter, 5-6 parts of pseudomonas, 4-5 parts of rhodococcus, 4-5 parts of bacillus amyloliquefaciens, 4-5 parts of clostridium and 3-4 parts of scenedesmus obliquus. The method has the advantages that the biochemical preparations contain diversified microorganisms with excellent degradation capacity for refractory pollutants, various strains are reasonably compatible with one another, accordingly, excellent degradation effects can be realized, and the method has a broad application prospect.

Description

Technical field [0001] The invention relates to the clean production field of threonine in the biological fermentation industry, and specifically provides a preparation method of a biochemical preparation for treating threonine fermentation wastewater. Background technique [0002] Threonine (Threonine, abbreviated as Thr), the scientific name 2-amino-3-hydroxybutyric acid, is an aliphatic amino acid, slightly sweet, named because its structure is similar to threose, and is a kind of protein that constitutes humans, animals and plants Essential amino acids are mainly used in medicine, chemical reagents, and nutritional supplements. They can strengthen dairy products and have the effects of restoring body fatigue and promoting growth and development. In recent years, with the development of the economy, the market demand for threonine has continued to grow steadily. It is one of the fastest-growing amino acid varieties, especially in chemical and biochemical, food additives, feed...
