Problems solved by technology

There are two main treatment methods currently used, one is to use biochemical treatment after dilution, the disadvantage is that the water consumption of dilution is large, and the active ingredients are not recovered and reused; the other is to use traditional concentration equipment to concentrate and then separate and recover. Such as two-effect, three-effect, the disadvantage is that the recovery cost is very high

Embodiment 4

[0033] Continuous to 3m 3 Add 2.5m of aspartame production waste water of the same composition as Example 1 in the enamel kettle 3 , use liquid caustic soda to adjust the pH to 7.5, control the temperature not to exceed 40°C, use 30m 2 Plate and frame filtration, the filter cloth is 750A type, and the filtrate to be filtered is stored for about 30m 3 At this time, the temperature of the feed liquid is raised to between 40 and 45°C through a plate heat exchanger, and then filtered through a 3μm bag filter, and then the 4080 nanofiltration membrane tube produced by GE Company is used for membrane separation treatment. When the temperature exceeds 45°C, in order to avoid damage to the membrane tube, the inlet pressure of the membrane should be controlled below 3.5mpa, and the pressure difference of the membrane should be controlled between 0.2-0.3mpa. The salt-containing clear liquid and concentrated liquid are collected and processed separately. The yield of concentrated liqu...

Abstract

The invention discloses an aspartame production waste water processing method, first, aspartame production waste water pH is adjusted to 6 to-8, the aspartame production waste water is filtered, and enters a high-pressure membrane for membrane separation treatment at 35 and 50 DEG C to respectively obtain a salt-containing clear liquid and an amino acid-containing concentrated liquid; the salt-containing clear liquid is concentrated for recovery of by-product salts; the amino acid-containing concentrated liquid is added with racemization agent salicylaldehyde for racemization at 60 to 100 DEG C, and after the reaction, DL amino acids can be obtained by concentration cooling and separation. The method solve the difficult problem of the treatment of organic wastewater with high salt content, the operation is convenient, the processing cost is low, the investment is relatively small, and large output can be achieved.

Description

technical field [0001] The invention belongs to the field of aspartame production, and in particular relates to a treatment method for recycling waste water containing amino acids in aspartame. Background technique [0002] Aspartame (Aspartame), alias aspartame, aspartame, food additive international code: E951, chemical name is L-aspartame-L-phenylalanine methyl ester (APM=L-aspartyl -L-Phenylalanine methyl ester), is a non-carbohydrate artificial sweetener. [0003] Aspartame is produced by the condensation of L-phenylalanine and L-aspartic acid, the molecular formula is C 14 h 18 N 2 o 5 , foreign trade names are Nutrasweet, Equal Tablets, also known as sweetener, protein sugar, aspartame, aspartame, aspartame, etc. At room temperature, it is white crystalline powder. Because of its high sweetness and low calorie, aspartame is mainly added to drinks, vitamin lozenges or chewing gum instead of sugar. Many diabetics and dieters use aspartame as a sugar substitute. ...
