| Summary: | The invention relates to the technical field of biochemical engineering, and discloses a method for recovering succinic acid and malic acid from succinic acid mother liquor, which comprises the following steps: acidizing the succinic acid mother liquor, separating in a first continuous chromatography, and collecting first chromatographic clear liquor containing succinic acid and malic acid; concentrating the primary chromatographic clear liquid, cooling, crystallizing and centrifuging to obtain a succinic acid crude product and filtrate; the filtrate enters a secondary continuous chromatography for separation, and a secondary chromatography clear liquid containing malic acid is collected. The succinic acid and the malic acid in the succinic acid crystallization mother liquor are effectively separated and recycled through two continuous chromatograms, the obtained product is good in purity and high in yield, the problems that in the prior art, an anion resin adsorption and desorption method is not high in deso |
