Disclosed are a functional material for synchronously stabilizing multiple metals and a preparation method thereof, and a method for rehabilitating soil or wastewater contaminated by heavy metals (metalloids). The preparation method includes: mixing a ferrous salt, a ferric salt, a manganous salt, water, a dispersing material, and a phosphate to obtain a first mixture, and subjecting the first mixture to a first precipitation reaction to obtain a first reaction mixture containing the phosphate; adjusting a pH value of the first reaction mixture containing the phosphate to 10-12 by adding an alkali thereto to obtain a second mixture, subjecting the second mixture to a second precipitation reaction to obtain a second reaction mixture; and subjecting the second reaction mixture to a solid-liquid separation to obtain a solid, washing the solid, and drying to obtain the functional material for synchronously stabilizing multiple metals.
