Zusammenfassung:The invention provides a preparation method of a biochar-loaded iron material for oxidizing and repairing organic pollution of soil water, which comprises the following steps: preparing a magnetic biochar compound, namely suspending and dispersing biochar powder in a soluble ferric salt solution, adding alkali liquor under a stirring condition, conducting reacting to generate precipitate until the pH value of a final mixed solution is 11-12, and sequentially separating, washing and drying the precipitate to obtain the magnetic biochar compound. According to the preparation method, the Fe3O4 is precipitated on the biochar while the Fe3O4 is generated, so that the time required for preparing the material is shortened, the steps are simpler, and the prepared biochar loaded iron material can quickly and efficiently catalyze and degrade polycyclic aromatic hydrocarbon. According to the soil water body remediation method, PAHs are catalyzed and oxidized by adopting a biochar-loaded iron material activated hydrogen
