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

Abstract

The invention relates to a treatment method for treating industrial wastewater produced by sodium glutamate prepared by a concentrated isoelectric process. The method adopts biological preparations for advanced treatment, and the biological preparations are composed of nitrosating bacteria, aerobic denitrifying bacteria, Bowman's Acinetobacter, Aspergillus niger, Rhodococcus, Alcaligenes faecalis, Streptomyces rubrum, Candida albicans, Paenibacillus polymyxa and the adsorbent carrier are mixed, and it contains a variety of substances with excellent degradation ability for refractory pollutants Microorganisms are reasonably compatible with each other, have good degradation effects, and have broad application prospects.

Description

technical field [0001] The invention relates to a treatment method for waste water, and specifically provides a treatment method for industrial waste water produced by preparing sodium glutamate through a concentrated isoelectric process. Background technique [0002] my country is a big producer and consumer of monosodium glutamate. At present, various economic and technical indicators have reached or approached the world's advanced level. With the rapid development of the MSG industry, the regional structure of MSG production is constantly changing. Nowadays, my country's monosodium glutamate industry has shown a relatively high degree of concentration, but with the implementation of national industrial policies, the state's efforts to control corporate pollution have increased, and people's misunderstanding of the health of monosodium glutamate , the MSG industry will also face adjustments, and some small and medium production capacity will gradually withdraw from the MSG...
