Problems solved by technology

[0004] The applicant has conducted long-term research on the treatment of xanthan gum fermentation wastewater. Chinese patent technology "CN104313004A, a preparation for treating xanthan gum production sewage" discloses a preparation for treating xanthan gum production sewage, which is a carrier and The composite microbial agent is prepared by mixing according to the weight ratio of 2:1. The carrier is chitosan. There are many bacterial strains contained in this preparation, the cultivation operation process is relatively difficult, and it cannot be reused.
The Chinese patented technology "CN106882909A, Environmental Protection Technology for Treatment of Xanthan Gum Fermentation Wastewater" also uses a biological agent, which is prepared by mixing four kinds of bacteria and a carrier, and the carrier is made of zeolite, kaolinite, starch, chitosan It is sintered from other raw materials, has good adhesion, can be suspended in water, reduces the sludge output, and can be reused by calcination, but the biological preparation cannot completely degrade ammonia nitrogen, and the water contains a large amount of nitro nitrogen and nitroso nitrogen.

Embodiment 1

[0030] The biological agent used to treat wastewater from the xanthan gum fermentation process is prepared according to the following process:

[0031] The kaolin and bentonite were mixed according to the mass ratio of 2:1, and then added to a ball mill equipped with ball milling media (5mm silicon carbide balls, ball mass ratio 1:5) for 30 minutes, dried at 80°C for 15 minutes, and then passed 100 Mesh sieve to collect the under-sieve;

[0032] Mix the polyvinyl alcohol, attapulgite, urea, water and the undersieve according to the mass ratio of 3:5:7:70:100, and then put them into the granulator for granulation to obtain wet granules with a diameter of 1mm , Then placed in 80 ℃ drying for 30 minutes, then placed in a resistance furnace 1000 ℃ calcination for 30 minutes, after natural cooling, the ceramsite is obtained;

[0033] Mix the bacterial agent A and the ceramsite according to the ratio of 1L: 2kg, and incubate at 30℃ for 6h.

[0034] Then add bacterial agent B, 40g / L sodium ...

Embodiment 2

[0039] The biological agent used to treat wastewater from the xanthan gum fermentation process is prepared according to the following process:

[0040] The kaolin and bentonite were mixed in a mass ratio of 2:1, and then added to a ball mill equipped with ball milling media (5mm silicon carbide balls, ball mass ratio 1:5) for 30 minutes, dried at 80°C for 15 minutes, and then passed 100 Mesh sieve to collect the under-sieve;

[0041] Mix the polyvinyl alcohol, attapulgite, urea, water and the undersieve according to the mass ratio of 3:5:7:70:100, and then put them into the granulator for granulation to obtain wet granules with a diameter of 2mm , Then dry at 80℃ for 30min, then calcined in a resistance furnace at 1000℃ for 40min, after natural cooling, ceramsite is obtained;

[0042] Mix the bacterial agent A and the ceramsite according to the ratio of 1L: 2kg, and incubate at 30℃ for 6h.

[0043] Then add bacterial agent B, 50g / L sodium alginate aqueous solution, stir evenly, and t...

Embodiment 3

[0049] Index detection of ceramsite of the present invention.

[0050] Porosity: Use GB / T1966-1996 boiling method to determine the porosity of the sample;

[0051] Mechanical strength: Use GBTl965 / 1996 porous ceramic bending strength test method to measure.

[0052] The specific indicators are shown in Table 1:

[0053] Table 1

[0054] Group Porosity% Mechanical strength Mpa Density g / ml Example 172.814.61.04 Example 270.615.31.08

[0055] It can be seen that the ceramsite carrier of the present invention has a porosity of more than 70%, a pore diameter of 0.1-10 microns, easy processing, high strength, high porosity, density close to water, in a suspended state, and good dispersibility in wastewater. , Is conducive to rapid adsorption and treatment of pollutants.

The biological preparation includes a combination of any two or more of Paracoccus denitrificans, Clostridium perfringens and Halomonas elogata. The bacteria in the biological preparation can form shortcut positive cycle, so the biological preparation has good synergistic performances, and can effectively treat pollutants in the wastewater.

Description

Technical field [0001] The invention belongs to the field of biotechnology, and specifically relates to a biological agent for treating waste water of a xanthan gum fermentation process. Background technique [0002] Water is the most precious wealth on the earth, and it is an indispensable substance for the survival and development of mankind and all living things. At present, the fresh water resources available for human use of the earth’s water resources are most of the surface water that exists in the underground aquifers below 800m in depth, accounting for only 2.6%. In fact, the real water resources that can be used as human life and production are only global A very small part of the total water volume. The world water crisis has seriously threatened the survival of mankind. More than one-fifth of the people in the world will face a situation of medium to high water shortage. This pressure is sending a water shortage warning to the world. The total amount of water resour...
