Problems solved by technology

[0002] At present, in the process of refining and decolorizing the production of lincomycin, after the used waste activated carbon is washed with part of butanol (activated carbon used for butanol decolorization) or purified water (activated carbon used for water decolorization), the waste carbon still contains A large amount of lincomycin is not easy to wash out, and then these waste activated carbons are added to the fermentation broth as filter aids during plate and frame filtration, and then disposed of together with the filter cake as hazardous waste, and the increase in pretreatment yield Very inconspicuous; also caused the loss of lincomycin in waste charcoal

Embodiment Construction

[0022] The method for reclaiming lincomycin from waste activated carbon after decolorization of lincomycin described in the present invention, the method is decolorization of lincomycin concentrated solution by activated carbon or solution of coarse powder dissolved by activated carbon or back extraction The waste activated carbon after the liquid is decolorized by activated carbon, the waste liquid after lincomycin in the alkalization liquid is extracted with saturated butanol water or a solution containing 5-10% butanol or butanol or the waste water separated in the process of recovering butanol, to The waste activated carbon is washed and filtered, and then extracted and refined with butanol, so as to recover the lincomycin in the decolorized waste carbon.

[0023] For this reason, the method for reclaiming lincomycin from the waste activated carbon after lincomycin decolorization described in the present invention specifically comprises the following steps:

[0024] ①. Mix...

Abstract

The invention discloses a method for recovering lincomycin from waste active carbon decolorized by lincomycin. The method comprises the following steps: washing decolorized waste active carbon by neutral or acid saturated butanol water or extracted waste liquor containing 5-10% butanol liquid or alkalization liquid and filtering, regulating pH of the filtrate by NaOH solution, and extracting and refining by butanol to recover lincomycin from decolorized waste active carbon. The method can help recover lincomycin from the waste active carbon decolorized by lincomycin, increase yield of lincomycin, and has great economical benefits and social benefits.

Description

Technical field [0001] The invention belongs to the technical field of medicine and chemical industry, and in particular relates to a method for recovering lincomycin from waste activated carbon after decolorization of lincomycin. Background technique [0002] At present, in the process of refining and decolorizing the production of lincomycin, after the used waste activated carbon is washed with part of butanol (activated carbon used for butanol decolorization) or purified water (activated carbon used for water decolorization), the waste carbon still contains A large amount of lincomycin is not easy to wash out, and then these waste activated carbons are added to the fermentation broth as a filter aid during plate and frame filtration, and then disposed of together with the filter cake as hazardous waste, and the increase in pretreatment yield Very inconspicuous; also caused the loss of lincomycin in the waste charcoal. Contents of the invention [0003] For above-mentio...
