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

[0032] (1) Take monosodium glutamate wastewater produced by an enterprise in Linyi City, and the wastewater enters the pre-anaerobic pool UASB. The hydraulic retention time is controlled to be 30h, and the temperature is 35°C, so that the macromolecular substances are broken into small molecular substances, and the organic nitrogen is converted into Inorganic nitrogen, the effluent enters the sedimentation tank;

[0033] (2) Add biological preparations to the sedimentation tank for advanced treatment, and the biological preparations include the following raw materials in parts by weight:

[0034] 12 parts of aerobic denitrifying bacteria, 12 parts of Paenibacillus polymyxa, 10 parts of Aspergillus niger, 10 parts of Rhodococcus, 9 parts of Alcaligenes faecalis, 7 parts of Streptomyces rubrum, 7 parts of Candida albicans, nitrosative bacteria 5 servings.

[0035] The aerobic denitrifying bacteria is Paracoccus pantotrophus ATCC35512.

[0036] The Paenibacillus polymyxa is Pae...

Embodiment 2

[0049] (1) Take the monosodium glutamate wastewater produced by a production workshop in Linyi City, and the wastewater enters the pre-anaerobic pool UASB, and the hydraulic retention time is controlled to 30h, and the temperature is 35°C, so that the macromolecular substances are broken into small molecular substances, and the organic nitrogen is transformed. Become inorganic nitrogen, and the effluent enters the sedimentation tank;

[0050] (2) Add biological preparations to the sedimentation tank for advanced treatment, and the biological preparations include the following raw materials in parts by weight:

[0051] 15 parts of aerobic denitrifying bacteria, 15 parts of Paenibacillus polymyxa, 12 parts of Aspergillus niger, 12 parts of Rhodococcus, 10 parts of Alcaligenes faecalis, 10 parts of Streptomyces rubrum, 10 parts of Candida albicans, nitrosative bacteria 7 servings.

[0052] The aerobic denitrifying bacteria is Paracoccus pantotrophus ATCC35512.

Embodiment 3

[0065] Embodiment 3 treats the example of waste water effect

[0066] Get monosodium glutamate waste water, according to embodiment 1-2 method kettle bottom material enters sewage treatment system respectively, sampling measures COD, ammonia nitrogen, total nitrogen data;

[0067] Compared with Example 1, the control group 1 did not add compound bacterial agents; compared with Example 1, the control group 2 had only wheat bran as the adsorbent carrier. Sampling and determination of COD, ammonia nitrogen, and total nitrogen data, the test data are as follows in Table 1:

Abstract

The invention relates to a treating preparation suitable for high-concentration nondegradable wastewater, which is prepared by mixing aerobic denitrifying bacterium, Paenibacillus polymyxa, Aspergillus niger, Rhodococcus, Bacillus foecalis alkaligenes, Streptomyces lateritius, Candida albicans, nitrococcus and an adsorbent carrier. The preparation contains multiple microbes having favorable degradation capacity for nondegradable pollutants; and due to the reasonable proportioning of the strains, the preparation has favorable degradation effect and has wide application prospects.

Description

technical field [0001] The invention relates to the field of waste water treatment, and specifically provides a treatment preparation suitable for high-concentration refractory waste water. 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 high-concentration, difficult-to-degrade industrial wastewater that is very difficult to treat. Due to the ineffective treatm...
