- 摘要：
Provided are a raw gas biological desulfurization device and a raw gas biological desulfurization method, whereby it becomes possible to efficiently treat high-load hydrogen sulfide. A biological desulfurization device for biologically removing hydrogen sulfide from a hydrogen-sulfide-containing gas (0a) generated by the methane fermentation of organic waste. The biological desulfurization device is characterized by being equipped with: a desulfurization column (1) in which a filling layer (1a) comprising a filler having a microorganism attached thereto is arranged; a watering means for watering (0d) onto the filling layer in the desulfurization column; a gas retention zone which is formed at the uppermost-stream end part of the filling layer in the desulfurization column; a hydrogen-sulfide-containing gas line (3) through which the hydrogen-sulfide-containing gas is introduced into the gas retention zone; a treated gas outflow line (13) through which a treated gas is to be discharged from the lowermost-st
