| Abstract |
Characteristics for hydrogen and VFA production (volatile fatty acid) from waste activated sludge was investigated using two stage reactor (acid formation reactor; first stage, photosynthetic reactor; second stage). The acid reactor used Submerged and external separation membrane. The photosynthetic reactor connected with the acid reactor. The COD removal rate in acid formation reactor with submerged and external separation membrane showed about 55% and 75%, respectively. The total VFA produced more in acid reactor with external separation membrane than in acid reactor with submerged separation membrane. The influent COD removal rate per total VFA production rate showed about 11% and 18%, respectively. Hydrogen gas production was not showed in acid reactor but showed in photosynthetic reactor. The hydrogen production per T-VFA in photosynthetic reactor connected with submerged and external separation membrane acid reactor showed about 50.1 ㎖ H₂/g T-VFA and 160.5 ㎖ H₂/g T-VFA, respectively. The Y value in steady state condition of photosynthetic reactor connected with submerged and external separation membrane acid reactor showed about 0.0028 ㎎-biomass ㎎-substrate- and 0.0004㎎-biomass . ㎎-substrate-` , respectively. |
