As the result of substrate(Glucose 5.000㎎/ℓ) removal characteristics comparision and gas production rate on the anaerobic fluidized bed according to the HRT variation. We got the conclusion as following; In the case shock loading, the microbials of AFB(anaerobic fluidized bed) reactor is more fitted than the microbials of general anaerobic digestion. The COD removal rate of the HRT 1.5days is 86% and the HRT 3.0days is about 96% one the AFB reactor. Substrate removal velocity of HRT 3.0days in AFB reactor is about 4.0㎏·COD/m³·days It shows that the microbials of AFB reactor is more actived 2 times than general anaerobic digestior. The gas production rate in the AFB reactor is 1.700~1.800㎎/day on HRT 1.5~3.0days and gas production rate perunit substrate is 0.4~0.51/g·Glucose.

The purpose of this research was to investigate loading rate of influent for acidogenic fermentation. Laboratory batch experiments were conducted, at 35℃, HRT 18hr, pH 6 and used 3.5L reactor. Loading rate of influent was varied 2.0 to 4.0g VSS/L, TOA concentration is decreased according to increasing loading rate Over 2.5g VSS/L. When loading rate is 2.0g VSS/L, hydrolysis percentage show the maximum value of 87%. Most of SCFA is consist of HAc, HPr, I-HBu and MBu. HAc concentration is 5,233㎎/L in the 2.0g VSS/L condition. So, for this study, we think that limiting loading rate is 2.5g VSS/L. SCFA species was investigated to HAc, HPr, I-HBu and nHBu during our studying. HAc/SCFA ratio is about 89.3%, SCFA production rate is highest to 1,104㎎ COD/L/d . gPCOD for 2.0g VSS/L loading rate.
