Abstract
Prior to utilization of energy and power generation, the biogas from anaerobic digestion of sewage treatment plant(46,000㎡/d) should be purified particularly hydrogen sulfide among the various kinds of impurities. This study has focused on the methane decreasing rate and the removal of both hydrogen sulfide and carbon dioxide. In the case of partial circulation, 59.7% of methane gas was decreased to 57.4% in spite of oxidation process with micro-bubble. Carbon dioxide was removed from 38% to 32% and 76.1% of hydrogen sulfide was removed where 1,400ppm was introduced to the DIWS system, which indicated that DIWS system can be of use for the hydrogen sulfide removal of biogas from sewage treatment plant.
