Device for extracting and separating organic carbon component in kelp culture water body

The utility model relates to a device for extracting and separating organic carbon components in a kelp culture water body. The device comprises a first-dimensional grading extraction system and a second-dimensional elution separation system, the first-dimensional graded extraction system comprises a sample supply module, a filter column, a first-stage extraction column and a second-stage extraction column; the output end of the sample supply module is sequentially connected with the filter column, the first-stage extraction column, the second-stage extraction column and a waste liquid collection module along the liquid flow direction; and the second-dimensional elution separation system comprises a first-stage elution module and a second-stage elution module. According to the utility model, on the basis of the first-dimensional grading extraction system, particulate carbon capture, inorganic carbonate removal and dissolved organic carbon extraction in the kelp culture water body are continuously carried out,
