Embodiment 1
[0037] A macroporous mesoporous silica carrier is prepared by a template method, and the carrier has a pore structure interconnected with each other.
[0038] Reduction-sulfurization of the carrier: place the carrier in a corundum cup in a vacuum tube furnace, evacuate it with argon, and then switch the gas path to 3vol.H 2 / Ar mixture, warm up to 570 o C, the time is 1.3h, naturally cool down to 250 o After C, after argon is evacuated, CS is introduced 2 gas to 13 o C / min increased to 700 o C, keep the temperature for 1.5h, cool down to room temperature naturally, form sulfur-oxygen bonds on the surface of the silica carrier, and serve as the adsorption sites for the culture medium sulfur bacteria.
[0039] The sulfur oxidizing bacteria culture medium includes KH 2 P0 4 , NaHP0 4 , MgSO 4 , KCl, and deionized water, and Cu 2+ , Zn 2+ , Ca 2+ , Fe 3+ ,Mn 2+ Trace elements, autoclaved at 121 °C for 20 min, inoculated with sulfur-oxidizing bacteria under sterile con...
