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, which cannot be afforded by most monosodium glutamate factories, and they have to maintain the status quo of excessive emissions for a long time

Embodiment 1

[0028] (1) Take the monosodium glutamate wastewater produced in the Fufeng production workshop, and the wastewater enters the pre-anaerobic tank UASB. The hydraulic retention time is controlled to 30h and the temperature is 35℃, so that the chain of macromolecular substances is broken into small molecular substances, and organic nitrogen is transformed into Inorganic nitrogen, the effluent enters the sedimentation tank;

[0029] (2) The sedimentation tank is added with biological agents for advanced treatment, and the biological agents include the following raw materials by weight:

[0030] 8 parts of aerobic denitrifying bacteria, 8 parts of Bacillus, 7 parts of Aspergillus niger, 7 parts of Rhodococcus, 5 parts of Alcaligenes faecalis, 5 parts of Streptomyces latus and 3 parts of Candida albicans.

[0031] The aerobic denitrifying bacteria are aerobic denitrifying bacteria ( Paracoccuspantotrophus ) ATCC35512.

[0032] The bacillus is Bacillus ( Bacillussp. ) CGMCCNO.9143 (see CN10...

Embodiment 2

[0044] (1) Take the monosodium glutamate wastewater produced in the Fufeng production workshop, and the wastewater enters the pre-anaerobic tank UASB. The hydraulic retention time is controlled to 30h and the temperature is 35℃, so that the chain of macromolecular substances is broken into small molecular substances, and organic nitrogen is transformed into Inorganic nitrogen, the effluent enters the sedimentation tank;

[0045] (2) The sedimentation tank is added with biological agents for advanced treatment, and the biological agents include the following raw materials by weight:

[0046] 10 parts of aerobic denitrifying bacteria, 10 parts of Bacillus, 9 parts of Aspergillus niger, 9 parts of Rhodococcus, 8 parts of Alcaligenes faecalis, 8 parts of Streptomyces latus and 5 parts of Candida albicans.

[0047] The aerobic denitrifying bacteria are aerobic denitrifying bacteria ( Paracoccuspantotrophus ) ATCC35512.

[0048] The bacillus is Bacillus ( Bacillussp. ) CGMCCNO.9143 (see CN...

Embodiment 3

[0059] Example 3 Example of wastewater treatment effect

[0060] Take the glutamic acid extraction wastewater from the Fufeng production workshop, and enter the bottom material into the sewage treatment system according to the method in Example 1-2, and sample and determine the data of COD, ammonia nitrogen, and total nitrogen;

[0061] Compared with Example 1, the control group 1 did not add the compound bacterial agent; compared with the example 1, the control group 2 had only wheat bran as the adsorbent carrier. Sampling to determine COD, ammonia nitrogen, total nitrogen data, the test data are as follows:

Abstract

The invention relates to a biological agent for glutamate wastewater treatment. The biological agent is formed by mixing aerobic denitrifier, bacillus, aspergillus niger, rhodococci, alcaligenes faecalis, streptomyces lateritius, Candida albicans and an adsorbent carrier. The biological agent contains various microorganisms with the good degradation ability to non-biodegradable pollutants, all the bacteria are reasonably matched, the good degradation effect is achieved, and the wide application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of biological environmental protection, and specifically provides a biological preparation for treating monosodium glutamate wastewater. Background technique [0002] With the rapid development of the economy and the continuous improvement of technology, my country has become a major producer and consumer of monosodium glutamate, but the amount of wastewater discharged during the production of monosodium glutamate is large, and the mother liquor discharged from the monosodium glutamate fermentation broth after isoelectric extraction of glutamic acid has CODCr High, high BOD5, high bacteria content, high sulfate radical (chloride ion before pH adjustment with sulfuric acid) content, high ammonia nitrogen content and low pH value (1.5-3.2) are characterized by "five highs and one low". It is a kind of industrial wastewater that is very difficult to treat. Due to the ineffective treatment of MSG wastewater, m...
