A microorganism desulfurizing and sulfur recycling method. A gas material flow containing hydrogen sulfide is fed into an absorption column and then is subjected to chemical absorption with an alkali solution sprayed from the top of the column in a counter-contact manner, wherein treated purified gas is discharged out from the top of the absorption column. A back-washing apparatus is arranged in the absorption column to wash the sulfur attached to a filling material. A rich solution, in which the hydrogen sulfide is dissolved, is fed into a rich solution tank from the bottom of the absorption column and then is fed into a bio-reactor for aeration, so that a carrier, on which desulfurization bacteria is immobilized, is fluidized and the sulfide in the absorption solution is biologically oxidized to generate elementary sulfur. The regenerated solution containing the sulfur then is fed into a settling tank through an overflow weir of the bio-reactor and a supernatant liquid is fed into a barren solution tank. The supernatant liquid then is fed back to the absorption column for being recycled through a barren solution pump. Sulfur slurry in the bottom layer is discharged through the bottom of the settling tank and then is subjected to solid-liquid separation in a centrifugal machine to obtain biological sulfur. A separated filtrate is fed back to the bio-reactor for being recycled. The bio-desulfurization technology is green and environment-friendly, is energy-saving and emission-reducing and can recycle resources, and has social, economical and environmental benefits.
