Title
A Study on Kinetic Analyses of High - rate Anaerobic Granular Sludge ( HAGS ) Reactor
최정우Jeung Woo Choi,현길수Kil Soo Hyun
Abstract
The objectives of this study using synthetic wastewater were to investigate the characteristics of high-rate anaerobic granular sludge(HAGS) process on organics removal and to analysis a reaction theory of the HAGS. As a results, COD_(Mn) removal rates at hydraulic retention time (HRT) of 0.25∼2days were 77∼95% and substrate removal was sensitive at less than the HRT of 6 hours, but stable at more than the HRT of 12hours. At COD loading rates of 0.12∼2㎏/㎥/d and influent TCOD_(Mn) of 250∼500㎎/L, MLSS and MLVSS in the reactor ranged from 28,900 to 30,130㎎/L. and from 21,010 to 22,040㎎/L, respectively. Yield coefficient (Y) and endogenous decay constant (k_d) were 0.0047∼0.095gVSS/gCOD and 0.0003∼0.0004day^(-1), respectively. The following equation for the HAGS reactor was given from the relationship between the specific substrate concentration and substrate removal rate coefficient of the second reaction rate coefficient obtained from the proposed equation of the HAGS reactor. S_e=S_0·(ψ·η/(320.8·ψ-1.755)·t_d)^½
