Problems solved by technology

The applicant's previous patent "CN201410029229.8, A Regeneration Method for Waste Powdered Activated Carbon" disclosed the regeneration process of activated carbon used in the amino acid purification process, including acid treatment, microbial treatment and alkali treatment. This method realizes the regeneration of activated carbon Regeneration, but the compatibility of microbial preparations is relatively complicated. Four strains are used for compatibility. The operation steps for cultivating multiple strains are cumbersome, and the requirements for compatibility ratio are high, and it is easy to cause bacterial contamination, which brings difficulties to enterprises.

Abstract

The invention belongs to the technical field of biology, and discloses a crystallized sugar decolourizing activated carbon regenerating process. The crystallized sugar decolourizing activated carbon regenerating process comprises the following steps: (1) preparing a composite alga liquid; (2) preparing a bacillus subtilis fermenting liquid; (3) regenerating activated carbon. According to the regenerating process disclosed by the invention, adsorbates, such as pigment, in the activated carbon can be reduced, and the specific area and the adsorption capacity of the activated carbon can be improved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a regeneration process of crystalline sugar decolorization activated carbon. Background technique [0002] Activated carbon regeneration (or activation) is to remove the adsorbate adsorbed on the micropores of activated carbon without destroying the original structure of activated carbon, restore its adsorption performance, and achieve the purpose of repeated use. Due to the high price of activated carbon itself, it is extremely uneconomical to discard it if it is only used once, resulting in waste of resources and increased costs. Amino acid production enterprises will use a large amount of activated carbon for decolorization in the amino acid purification process. How to efficiently regenerate activated carbon saturated with adsorption to achieve economical and rational utilization has become a key issue in the activated carbon industry, and it is also a hot spot of re...
