Abstract
The invention discloses a peat absorbent and a method thereof for processing soil polluted by spilled oil. The peat absorbent is prepared by mixing meadow peat, sphagnum peat and a nitrogenous fertilizer which are proportioned in a way that: in the total weight of 100, the weight percentage of the meadow peat is 25 to 33, the weight percentage of the sphagnum peat is 20 to 33 and the weight percentage of the nitrogenous fertilizer is 25 to 50. The method for processing the soil polluted by the spilled oil is implemented orderly through the following steps: spraying the absorbent into the polluted soil in a shortest time after the soil is polluted by the spilled oil, wherein the input amount of the absorbent is 0.1 to 0.17 times as great as oil spillage; adding quicklime into the soil polluted by the spilled oil, wherein the input amount of the quicklime is 0.1 to 0.3 times as great as the oil spillage; ploughing up the polluted soil sprayed with the absorbent and added with the quicklime, wherein the depth of ploughing is determined according to the penetration depth of the oil; irrigating the polluted soil in a way that the moisture of the soil reaches 80 to 85 percent; and monitoring the content of petroleum hydrocarbon in the polluted soil until the soil meets environmental standards for reuse.
