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

[0035] (1) Take monosodium glutamate wastewater produced by concentrated isoelectric process and enter the pre-anaerobic tank UASB. Control a certain hydraulic retention time to 20h and temperature to 30°C, so that the chain of macromolecular substances is broken into small molecules. Substance, organic nitrogen is transformed into inorganic nitrogen, and the effluent enters the sedimentation tank;

[0036] (2) The sedimentation tank adds advanced treatment of bioremediation agents, and the bioremediation agents include the following raw materials by weight:

[0037] 7 parts of nitrosating bacteria, 7 parts of aerobic denitrifying bacteria, 5 parts of Acinetobacter baumannii, 5 parts of Aspergillus niger, 5 parts of Rhodococcus, 3 parts of Alcaligenes faecalis, 3 parts of Streptomyces rhodochrous, 3 parts of Candida albicans 3 parts, 2 parts of Bacillus polymyxa.

[0038] The nitrosating bacteria are specifically nitrosating bacteria ( Nitrosomonas europaea ) ATCC19718;

Embodiment 3

[0074] Example 3 Example of wastewater treatment effect

[0075] Take monosodium glutamate to extract the waste water, and enter the bottom material into the sewage treatment system according to the method in Example 1-2, and sample the data of COD, ammonia nitrogen, and sulfide;

[0076] Compared with Example 1, the control 1 group did not add the compound bacterial agent; the control 2 group compared with Example 2 the adsorbent carrier was only straw, and the control 3 group compared with Example 2 the adsorbent carrier was only humic acid. Sampling and determination of COD, ammonia nitrogen, sulfide data, the test data is as follows:

Abstract

The invention relates to a bioremediation preparation for preparing industrial wastewater produced by sodium glutamate by a concentrated isoelectric point technology. Coccus, Alcaligenes faecalis, Streptomyces sclerotiorum, Candida albicans, Paenibacillus polymyxa are prepared by mixing with adsorbent carrier, which contains a variety of microorganisms with excellent degradation ability to refractory pollutants. Reasonable compatibility, good degradation effect, it has broad application prospects.

Description

Technical field [0001] The invention relates to the field of wastewater treatment by microbial preparations, and in particular provides a bioremediation preparation for preparing industrial wastewater produced by sodium glutamate by concentrated isoelectric point technology. Background technique [0002] my country is a major producer and consumer of MSG. At present, various economic and technical indicators have reached or approached the world's advanced level. The regional structure of MSG production is constantly changing with the rapid development of the MSG industry. Nowadays, my country's MSG industry has shown a relatively high degree of concentration, but with the implementation of national industrial policies, the country has increased its efforts to control corporate pollution, and the people’s misunderstanding of the health of MSG by "talking about MSG discoloration" , The MSG industry will also face adjustments, some small and medium-sized production capacity will gra...
