Problems solved by technology

[0004] 1) The content of organic matter is high, and the COD concentration is 60000-70000mg / L;
[0005] 2) High sugar content, the total sugar content of wastewater is about 2.5%;
[0007] 4) The composition of wastewater is complex, mainly residual sugar, protein, organic acid, metabolic intermediate products and a small amount of vitamin B 12 Wait;
[0008] 5) The color of the wastewater is deep, dark brown, and there are many suspended solids
[0009] for vitamin B 12 There is currently no effective and high value-added utilization method for production wastewater, and it can only be discharged directly into the sewage treatment system, which not only increases the load and treatment costs of the sewage treatment system, but also causes a waste of resources

Abstract

The invention relates to a method for partially replacing water used for fermentation production of tylosin with production wastewater of vitamin B12, belonging to a recycling method. According to themethod, production wastewater of vitamin B12 after pretreatment, adsorption treatment, ceramic membrane filtration treatment and ultrafiltration treatment is directly reused in fermentation production of tylosin as water used for production. For the method, the treated production wastewater of vitamin B12 is directly reused in fermentation production of tylosin, thus the zero discharge of the wastewater of vitamin B12 is realized, the environmental pollution index and environmental protection treatment cost are reduced, a reliable basis is provided for the clean industrial production of vitamin B12, meanwhile, the water used for fermentation production of tylosin also can be reduced, thus the production cost of tylosin is reduced, and a guarantee is provided for the sustainable development of tylosin. In the method, the treatment process of the wastewater of vitamin B12 is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation wastewater treatment and reuse, and in particular relates to a vitamin B 12 The method of partially replacing the production water of tylosin fermentation with production wastewater. Background technique [0002] Vitamin B 12 It is a cobalt-containing water-soluble vitamin, the main component of which is cyanocobalamin. It is clinically used to treat pernicious anemia and restore hematopoietic function, and is also used for nervous system diseases such as multiple neuritis and peripheral nerve paralysis. It is also used to treat liver diseases such as hepatitis and cirrhosis. For a long time, vitamin B 12 The clinical usage has grown steadily. In addition, vitamin B 12 It also forms a multivitamin product together with other vitamins, and is widely sold as an OTC drug and health food. [0003] Production of vitamin B by two-step fermentation 12 During the process, a large a...
