Description
Technical field
The present invention relates to biofermentation industry xanthan gum clean manufacturing field, a kind of xanthan gum production waste water is specifically provided
Biochemical preparation and preparation method thereof.
Background technique
Xanthan gum (xanthan gum) is the northern research department (Northern of United States Department of Agriculture's the 1950s
Regional Research Laboratories, NRRL) from sarson Huang sporangium (Xanthom onas cam
Pestris) NRRLB21459 has found the neutral water soluble polysaccharide of secretion, also known as xanthan gum.It is by glucose, mannose
The outer heteroglycan of a kind of extracellular microbial formed with glucuronic acid with 218: 2: 2 molar ratio, " pentasaccharides repetitive unit " main chain
It is formed by 2 D-Glucose molecules through β-Isosorbide-5-Nitrae glucosides key connection, the skeleton structure with like fibrous element, in every 2 glucose
A carbon key on be connected with three carbohydrate side chains being made of 2 sweet glycan and 1 glucuronic acid.Unique point of xanthan gum
Minor structure imparts the physicochemical property of its numerous brilliance, such as good thickening property, thixotropy, emulsibility, pseudoplastic behavior.It is also
One important characteristic is can to generate reciprocation with other polysaccharides viscosity be caused to increase, meanwhile or a kind of through repeatedly
The green matter of the non-toxic and safe of confirmation, therefore become in food industry widely used a kind of bacterial polysaccharides and at present in the world
One of the biogum that best performance is got over.Since early 1960s U.S. Kelco company puts into industrialized production, xanthan gum
Product has been widely used in fields such as food, light industry, medicine, weaving, cosmetics, oil exploitation and fire-fightings.
Currently, the production method of xanthan gum mainly has fermentation method, protein Hydrolyze method and three kinds of chemical synthesis, wherein micro-
Biological fermentation process has become the main stream approach of production xanthan gum.Fermentation method produces xanthan gum need to be through everfermentation, film filtering, concentration
The technological operations such as crystallization, centrifuge separation, ion exchange, drying, screening, packaging will generate a large amount of after concentrate centrifuge separation
Impurity amino acid, protein, residual sugar, inorganic salt and other material.
As the demand to xanthan gum surges, China has become the maximum xanthan gum producing country in the whole world.Because xanthan gum is
Biofermentation polysaccharide, the problem of fermented waste fluid will necessarily being brought to pollute, since xanthan gum has insoluble machine agent, spy soluble easily in water
It selects so need to add a large amount of organic solvents into fermentation liquid in production, xanthan gum is precipitated out from fermentation liquid, then with
Distillation side obtain product, extract generate waste water characteristic be containing a large amount of thallus and with organic matter (COD), there are also rectifying column recycling
Efflux wastewater and equipment cleaning after drinking, major pollutants are the organic matters such as unused starch, protein.Xanthan Gum Wastewater is also
Having an evident characteristic is exactly containing gelatin substance, it is difficult to which degradation treatment mainly contains part containing a large amount of fermentation pollutant
The inorganic salts such as sodium chloride, sodium nitrate, calcium chloride and a large amount of carbohydrate and organic molecular species such as residual sugar, acetic acid, pyruvic acid etc.,
CODcr is in 4000mg/L or more.If processing is bad, not only pollute the environment, can also waste biological substance therein, while right

Matter, but its disadvantage also can not be ignored, such as equipment will be cleaned often, prevent the extensive use of the method in the treatment of waste water.It is existing
There are also wastewater treatment is used for using physical absorption in technology, absorption method depends on the huge specific surface area of adsorbent, passes through
Physical absorption or chemisorption remove the pollutant in water.Active carbon is because having pore structure abundant and huge specific surface
Product, and its chemical stability is good, and adsorption capacity is strong, is often widely used as a kind of important sorbent material, but its at
This is higher.There are also being adsorbed using the nonmetallic ions mineral such as attapulgite, but natural non-metallic mineral have as adsorbent
Following limitation: natural non-metallic mineral density is larger and specific surface area is limited, and natural non-metallic mineral surfaces mostly band is negative
Electricity, and natural non-metallic fine ore such as clay minerals are directlyed adopt as adsorbent, solid-liquid is difficult to separate after having absorption
Problem.
Chemical method degradation process is then simple but random.Xanthan gum at high operating temperatures, can occur with oxidizing substance
Thermal degradation, but this method needs a large amount of heat.And current bioremediation is required to pre-process such as flocculation, air bearing.With
Physical method, chemistry are compared, and micro- raw processing waste water has the distinguishing features such as economical and efficient and can realize the recycling of wastewater treatment, nothing
Evil, so that microbial method occupies critical positions in always.
