Problems solved by technology

[0014] The main problem in MSG wastewater treatment is that the investment and operation costs are too high;
[0015] At present, there is no suitable and effective treatment method. Although anaerobic treatment with low cost can be used, it still cannot solve the problem of high sulfate
[0016] The treatment methods for monosodium glutamate wastewater mainly include physical methods, such as flocculation sedimentation method, chemical method, biofilm method, etc., but the effect is not particularly obvious. Therefore, it is necessary to design a high removal rate of BOD and COD for the above-mentioned monosodium glutamate wastewater. Wastewater treatment method

Abstract

The invention belongs to the field of treatment of wastewater in food enterprises and in particular relates to a treating agent of wastewater in monosodium glutamate production enterprises and also relates to a monosodium glutamate production wastewater treatment method. The monosodium glutamate production wastewater treating agent comprises the following components in parts by weight: a physical water purifying agent, a compound microbial agent and an enzymic preparation, wherein the physical water purifying agent comprises 1-5 parts of activated carbon, 1-5 parts of organically modified zeolite and 1-5 parts of polyacrylamide; the compound microbial agent comprises 0.02-0.1 part of konjac acidovorax powder, 0.05-0.2 part of arthrobacter powder, 0.05-0.2 part of bacillus laterosporus powder and 0.04-0.2 part of moraxella powder; and the enzymic preparation comprises 0.05-0.1 part of xylanase, 0.04-0.09 part of glutaminase and 0.01-0.06 part of acid proteinase. By adopting the wastewater treating agent and the wastewater treatment method, complex large-particle organic matters difficult to degrade are hydrolyzed into simple organic matters easy to degrade, thus greatly reducing the content of SS (suspended substance) in the wastewater, and the treated wastewater has high BOD (biochemical oxygen demand) and COD (chemical oxygen demand) removal rates and reaches the specified discharge standard.

Description

technical field [0001] The invention belongs to the field of waste water treatment of food enterprises, and in particular relates to a treatment agent for waste water from monosodium glutamate production, and also relates to the above-mentioned treatment method for waste water from monosodium glutamate production. 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 volume of monosodium glutamate wastewater is large, the content of organic matter is high, the COD reaches 20-80g / L, the content of suspended solids and ammonia nitrogen is high, and the pH The 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. ...
