The present in­ vention is a biological desulfurization device characterized in that: provided are a biogas inflow line (5) for allowing biogas to flow in from an end of biological desulfurization a column (1), a treated gas outflow line (7) for discharging treated gas to a subsequent stage of packed a bed (la) which is another end of the biological desulfurization column and bears microorganisms, and a circulated gas line (8) for circu­ lating some of the treated gas to the end of the biological desulfurization column where the biogas flows in; and, in an arithmetic unit (11), a hydrogen sulfide load quantity is cal­ culated from measurement values of hydrogen a sulfide con­ centration meter (3) and a gas flowmeter (4) provided to the biogas inflow line (2), a circulated gas amount regulatory mechanism (9) being actuated according to the results there­ of adjust to the amount of circulated gas passing through the circulated gas line (8).
