| Abstract |
The relationship between SMP (soluble microbial products) and membrane fouling in the MBR (submerged hollow-fiber membrane bio-reactor) was investigated. The phenol was used as a substrate. The MBR was performed under condition that SMP concentration is changed from 20㎎/L to 60 ㎎/L. The membrane fouling increased with increasing of SMP concentration. The effect of resistance values on the membrane fouling was the order of R_(c)>R_(g)>R_(f)>R_(m). The increase of viscosity and non-biodegradable matters in the MBR was closely connected with the SMP concentration. The concentration of SMP should be kept less than 40 ㎎/L for stable operating of MBR. The T_(max) (time for maximum) decreased with increasing of SMP concentration. The removal rate of organic matters and total nitrogen in the MBR showed over 98% and 90%, respectively. |
