Abstract: A method for preparing a biogenic manganese oxide (BMO)@sponge biomaterial, in which a divalent manganese ion solution and a sponge carrier are added to a pre-sterilized culture medium, and then a manganese oxidizing bacterium with an accession number of ATCC 23483 is inoculated. The culture medium was cultured and freeze-dried to obtain the BMO@sponge biomaterial. This application further provides a method for treating an antibiotic-containing wastewater, in which a BMO@sponge biomaterial prepared by such method and a peroxymonosulfate (PMS) added to the wastewater. The PMS is activated by the BMO@sponge biomaterial to generate active substances such as hydroxyl radicals, sulfate radicals and singlet oxygen radicals, which can efficiently degrade the antibiotic into CO2 and water through a series of physical and chemical reactions and free radical chain reactions.

Abstract: A manganese carbonate-supported ferrihydrite material preparation method, in which manganese sulfate and ammonium bicarbonate are respectively dissolved to obtain a manganese sulfate solution and an ammonium bicarbonate solution, and the manganese sulfate solution is added with ferrihydrite, dropwise added with the ammonium bicarbonate solution and reacted under magnetic stirring to obtain a precipitate. The precipitate is washed with distilled water and dried in a drying oven to obtain the manganese carbonate-supported ferrihydrite material. A method for treating wastewater polluted by arsenic (As) and antibiotics by using the manganese carbonate-supported ferrihydrite material is also provided.
