| Abstract |
Biofilm reactors were numbered in terms of temperature, and biofilm reactor No.1 represented 25℃ and No.2 15℃. At 24hr of HRT, BOD removal efficiency was 94.7% at biofilm reactor No.1 and 92.3% at No.2, respectively, while it was about 90.0% for biofilm reactor No.1 and No.2 at 18hr of HRT. However, BOD removal efficiency was decreased below 12hr of HRT. At 25℃ the half saturation constant(K_s) and maximum specific substrate removal rate(k_(max)) were 228 ㎎/L and 0.96 day^(-1), respectively. In addition, the microbial yield coefficient(Y), decay coefficient(K_d), and maximum specific growth rate(μ_(max)) were 0.248 ㎎VSS/㎎BODre, 0.048 day^(-1), and 0.372 hr^(-1), respectively. On the other hand, at 15℃ the saturation constant (K-s) and maximum specific substrate removal rate(k-max) were 600 ㎎/L and 1.82 day^(-1). The microbial yield coefficient(Y), decay coefficient(K-d), and maximum specific growth rate were 0219 ㎎VSS/㎎ BODre, 0.045 day^(-1), and 0.487 hr^(-1), respectively. |
