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 method of preparing a FeMnCeOx biomaterial is provided, including the following steps. A Pseudomonas sp. strain KW-2 is obtained. A culture medium with a pH of 6.5-7.8 is prepared, which includes 0.1 g/L K2HPO4, 0.2 g/L MnSO4·7H2O, 0.2 g/L NaNO3, 0.1 g/L CaCl2), 0.1 g/L NH4Cl, 0.1 g/L (NH4)2CO3, 35 g/L NaCl and 150 mg/L ferric ammonium citrate. The culture medium is autoclaved, inoculated with the KW-2 strain, cultured for 1-3 days, added with a cerium nitrate solution, cultured for 3-7 days and centrifuged at 4,000-8,000 rpm for 10-20 min to collect a precipitate. The precipitate is rinsed 5-8 times with deionized water and 0.01 mol/L phosphate buffered saline (PBS) and freeze-dried at −60° C. to obtain the FeMnCeOx biomaterial. A method for treating antibiotic wastewater using the FeMnCeOx biomaterial is also provided.
