<p><P>PROBLEM TO BE SOLVED: To provide a method for reducing hydrogen sulfide and a device for reducing hydrogen sulfide by which the concentration of hydrogen sulfide can efficiently be reduced. <P>SOLUTION: The hydrogen sulfide reduction device 1 is provided with: four pieces of 100 L tanks stored with water 8, respectively; a hydrogen sulfide feed tube 3 connected to an enclosure 3A enclosing a place where a hydrogen sulfide-containing hot spring gas 3B is generated so as to be an almost sealed state, and further, sucking the hot spring gas 3B so as to be fed to the first tank 2; a blower 4 of feeding air to the water 8 in each tank through each air feed tube 4A, so as to be aerated; and a microorganism feeder 5 of feeding liquid microorganisms to the water 8 in the second tank 2A. The first tank 2 and the second tank 2A, the second tank 2A and the third tank 2B, and the third tank 2B and the fourth tank 2C are communicated by communication tubes 6 made of vinyl chloride, respectively, and the water 8 can be moved in the communication tubes 6. Further, the fourth tank 2C is fitted with a drain tube 7 of draining the water 8, and the upper part of each tank is opened. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
