Description
Technical field
The invention belongs to food enterprise field of waste water treatment, be specifically related to a kind of gustatory production wastewater treatment agent, also relate to above-mentioned gustatory production wastewater treatment process.
Background technology
Monosodium glutamate is a kind of food freshener be widely used, produce monosodium glutamate and will produce a large amount of high concentrated organic wastewaters, the gourmet powder waste water water yield is large, organic content is high, COD reaches 20-80g/L, suspended substance and ammonia-nitrogen content high, pH value is low, intractability is very big, processing cost is high, therefore a lot of glutamate production producers fails effectively to process gourmet powder waste water, great harm is brought to environment and social development, monosodium glutamate industry factory effluent pollution on the environment problem is on the rise, in well-known Basin of Huaihe River pollution problem, it is the second largest source of pollution being only second to paper waste, the improvement of gourmet powder waste water has become the great difficult problem of restriction glutamate production enterprise development.
China just to begin one's study the treatment process of gourmet powder waste water from late 1970s, but not yet there is very big breakthrough so far, the key of its problem is just that in gourmet powder waste water, chlorine ion concentration is high, general freezing isoelectric point method produces the content of chlorion in the waste water of monosodium glutamate discharge up to 10-30g/L, restraining effect is created to anaerobic treatment process, but result of study shows, when chlorine ion concentration is less than 6g/L, chlorion to the restraining effect of anaerobic process by not obvious.
The main source of gourmet powder waste water is:
(1) waste liquor after fermentation liquor extraction L-glutamic acid or ion-exchange tail washings;
