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
Xanthan gum can be thermally degraded with oxidizing substances at high temperature, but this method requires a lot of heat

Embodiment 1

[0040] The biological treatment process of xanthan gum fermentation waste is characterized in that, comprises the steps:

[0041] (1) Filtrate the xanthan gum fermentation liquid (Xanthomonas fermentation liquid) to collect the sterilized liquid (the sterilized liquid is used to prepare xanthan gum) and bacterial protein to prepare feed;

[0042] The preparation method of the feed is as follows: add bean dregs of equal quality to the bacterial protein, adjust the pH value to 12, slowly heat to 80°C, then stir and hydrolyze for 30 minutes, and finally adjust the pH to 7.0; then, add straw powder and fish bone powder , distiller's grains, and stir until it becomes a paste; finally, steam is introduced to raise the temperature to 105°C, and distillation is carried out for 10 minutes; the mass ratio of straw powder, fish bone powder, distiller's grains and bean dregs is 3:3:2:5, and finally the distillate Dry and pulverize to obtain powdery nutritional feed;

[0043] (2) After th...

[0088] Explanation of test effect

[0089] Experimental benefit of powdered nutrient feed, the pigs used in the experiment were Duroc

[0090] Tests show that, given the nutritional feed prepared by the present invention compared with common feed, the growth ability of pigs is significantly higher than that of the control group, and the digestive tract diseases such as diarrhea and constipation in the experimental group during the feeding period are significantly reduced, and the smell of feces is also significantly reduced, and the number of mosquitoes and flies is also significantly lower than that of the control group. The control group is small, and the economic benefit is obviously improved.

[0091] Example of sewage treatment effect

[0092] Take the Fufeng production workshop, xanthan gum fermentation sewage, enter the sewage treatment system according to the method of embodiment 1-2 respectively, and take samples to measure COD, ammonia nitrogen, total nitrogen data;...

Abstract

The invention relates to the biological treatment process of xanthan gum fermentation waste. According to the biological treatment process, feeds are prepared from zymophyte proteins, and sewage is drained after being subjected to biological treatment and physical treatment. A biological treatment agent is prepared from the following raw materials in volume ratio: 5 parts of pseudomonas aeruginosa, 3 parts of penicillium ochrochloron, 3 parts of acidithiobacillus ferrooxidans, 3 parts of rhodococcus, 4 parts of bacillus amyloliquefaciens, 2 parts of clostridium glycolicum and 1 part of scenedesmus obliquus. The biological treatment agent contains microorganisms with excellent degradation capacity to non-biodegradable pollutants; and by virtue of reasonable compatibility of strains, the biological treatment agent has good degradation effect and wide application prospect.

Description

technical field [0001] The invention relates to the field of clean production of xanthan gum in the biological fermentation industry, and specifically provides a biological treatment process for xanthan gum fermentation waste. Background technique [0002] Xanthan gum (xanthan gum) is a neutral water-soluble polysaccharide secreted from Xanthomonas cam pestris NRRL B21459 by the Northern Regional Research Laboratories (NRRL) of the US Department of Agriculture in the 1950s. Also known as xanthan gum. It is a microbial extracellular heteropolysaccharide composed of glucose, mannose and glucuronic acid in a molar ratio of 218:2:2. Its "pentasaccharide repeat unit" main chain consists of two D-glucose molecules via β-1 , connected by 4 glycosidic bonds, has a cellulose-like skeleton structure, and a carbon bond in every 2 glucose is connected with a trisaccharide side chain composed of 2 mannans and 1 glucuronic acid. The unique molecular structure of xanthan gum endows it ...
