Ex-situ remediation device for polluted underground water

The utility model provides a polluted underground water ex-situ remediation device. The polluted underground water ex-situ remediation device comprises a first dosing tank, a second dosing tank, a third dosing tank, a mixed reaction tank, a tubular static mixer and a manganese sand filter tank, the first chemical adding tank is used for adding 2, 2-azino-di (3-ethyl-benzothiazole-6-sulfonic acid) diammonium salt, the second chemical adding tank is used for adding KMnO4, and the third chemical adding tank is used for adding syringaldehyde and/or 3 ', 5-dimethoxy-4'-hydroxyacetophenone. The device can synchronously and efficiently remove phenols, perfluoroalkyl acids and sulfonamides pollutants in polluted underground water, is large in short-term treatment capacity and high in efficiency, does not generate secondary pollution, can maintain the stability and activity of a repairing agent while ensuring efficient removal of organic pollutants, and effectively reduces the process cost. 本实用新型提供了一种异位修复受污染地下水装置，包括第一
