Zusammenfassung:	The utility model relates to a graded extraction device for humic acid in peat. Comprising a natural peat storage bin, the natural peat storage bin is connected with an inlet of a wet ball mill, an outlet of the wet ball mill is connected with an oxidation activation reaction kettle, an outlet of the oxidation activation reaction kettle is connected with a first centrifugal machine, a centrifugate outlet of the first centrifugal machine is connected with an acidification reaction kettle, and an outlet of the acidification reaction kettle is connected with a second centrifugal machine. A centrifugal residue outlet of the second centrifugal machine is connected with the ulmic acid and black humic acid separation unit, and a liquid phase outlet of the second centrifugal machine is connected with the fulvic acid unit. According to the utility model, the peat is subjected to multi-stage activation treatment of physical-chemical-oxidative activation, so that the content of fulvic acid in the peat, the activity of h
