Abstract |
The kinetic of metabolism was investigated by using the submerged hollow fiber membrane separation activated sludge process, with HRT of 8 hours which the food wastewater was fed as a substrate. The kinetic model was studied under the unsteady state and the steady state condition. The concentration of MLVSS was increased by the time course and maintained about 10,000㎎/L after the first 70days. The yield factor(Y) and decay coefficient(K_d) were calculated as 0.7218㎎ VSS/㎎ COD and 0.1666day^(-1) at the unsteady state condition, respectively. At the steady state condition. Y and kd were calculated as 0.00068㎎ VSS/㎎ COD and 0.0002day^(-1), respectively. The resistance values of R_c, R_g, R_f, and R_m were calculated as 25.97×10^7m^(-1), 1.97×10^7m^(-1), 0.29×l0^7m^(-1) and 0.02×10^m^(-1), respectively. |
