Treatment process of monosodium glutamate fermentation wastewater

Abstract

The invention relates to a treatment process of monosodium glutamate fermentation wastewater. The wastewater is subjected to physical adsorption and composite bacteria treatment, wherein composite bacteria comprises the following components in parts by weight: 7 parts of azotobacter chroococcum, 5 parts of rhodococcus, 5 parts of bacillus amyloliquefaciens, 4 parts of clostridium papyrosolvens, 4 parts of penicillium ochrochloron, 3 parts of pseudomonas aeruginosa and 2 parts of bacillus cereus. As the composite bacteria contain various microorganisms that have an excellent degradation capability for refractory pollutants, and respective bacteria are combined reasonably, a good degradation effect is realized, and the treatment process of the monosodium glutamate fermentation wastewater has a broad application prospect.

Description

technical field

[0001] The invention relates to a method for treating waste water, and in particular provides a treatment process for monosodium glutamate fermentation waste water. Background technique

[0002] Monosodium glutamate is a widely used food freshening agent. The production of monosodium glutamate will produce a large amount of high-concentration organic wastewater. The monosodium glutamate wastewater has a large amount of water, high bacterial content, high organic content, COD reaches 20-80g / L, suspended solids, The content of sulfate and ammonia nitrogen is high, the pH value is low, the treatment is extremely difficult, and the treatment cost is extremely high. Therefore, many monosodium glutamate manufacturers fail to effectively treat monosodium glutamate wastewater, which has brought great harm to the environment and social development. The monosodium glutamate industry The pollution caused by production wastewater to the environment is becoming more and m...
