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...
