7. A water treatment method, comprising:
providing a water treatment composition, wherein the water treatment composition comprises a bulk catalytic material and an oxidant, the bulk catalytic material comprises iron atoms or ions, manganese atoms or ions, and magnesium atoms or ions, in the bulk catalytic material, a content of the iron atoms or ions is 0.1 mg/g to 1 mg/g, a content of the manganese atoms or ions is 0.1 mg/g to 1.5 mg/g, and a content of the magnesium atoms or ions is 2 mg/g to 6 mg/g; and
mixing the water treatment composition with organic wastewater, so as to decompose organics in the organic wastewater.
