Problems solved by technology

Activated carbon is widely used as an important adsorbent material because of its rich pore structure and huge specific surface area, good chemical stability and strong adsorption capacity, but its cost is high
There are also non-metallic ionic minerals such as attapulgite for adsorption, but natural non-metallic minerals have the following limitations as adsorbents: natural non-metallic minerals have high density and limited specific surface area, and the surface of natural non-metallic minerals is mostly negatively charged. And directly using natural non-metallic powder ore such as clay minerals as the adsorbent will have the problem of difficult separation of solid and liquid after adsorption
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

Abstract

The invention relates to a biological preparation for treating sodium glutamate fermentation sewage. The biological preparation comprises a physical preparation and a complex microbial agent, wherein the complex microbial agent comprises the following components in parts by weight: 4-5 parts of Azotobacter chroococcum, 4-5 parts of phanerochaete chrysosporium, 5-6 parts of Bacillus amyloliquefaciens, 4-6 parts of Clostridium papyrosolvens, 3-4 parts of penicillium ochrochlorron, 3-4 parts of Pseudomonas aeruginosa and 2-3 parts of bacillus cereus. The biological preparation contains multiple microorganisms having excellent degradation capacity to non-biodegradable pollutants, and by virtue of reasonable compatibility of the strains, the good degradation effect is achieved, and the application prospect of the biological preparation is wide.

Description

technical field [0001] The invention belongs to the field of clean production of sodium glutamate, and specifically provides a biological preparation for treating sewage fermented by sodium glutamate. Background technique [0002] The main component of monosodium glutamate is monosodium glutamate, which is a widely used food freshening agent. The production of monosodium glutamate will produce a large amount of high-concentration organic sewage. The monosodium glutamate sewage has a large amount of water, high bacterial content, and organic content High, COD reaches 20-80g / L, high content of suspended solids, sulfate radicals and ammonia nitrogen, low pH value, extremely difficult to deal with, and high cost of treatment. Therefore, many monosodium glutamate manufacturers fail to effectively treat sewage, which is harmful to the environment and Social development has brought great harm, and the environmental pollution caused by MSG industrial production sewage is becoming mo...
