초록

역세척이 가능한 평막형 분리막 모듈을 분리막 생물반응기(MBR)에 침지시켜 운전 시간에 따른 흡입 압력을 측정하였다. MLSS 8,000 mg/L 활성 슬러지 수용액에 공칭 세공크기가 0.2 ㎛, 유효막면적이 128 cm2 인 분리막 모듈을 침지시킨 후 투과 유속, quorum qeunching (QQ) 비드를 변화하며 흡입 압력을 확인하였다. Vacant bead (VB), BH4와 DKY-1의 실험군에서 FR과 SFCO 운전방식에 따른 효과를 비교, 분석하였다. 투과 유속 40 L/m2 ⋅h 이고 DKY-1 QQ 비드를 주입할 경우 흡입 압력 감소는 가장 효과적이었다. 또한 역세척에 의한 흡입 압력 감소 효과는 DKY-1 QQ 비드의 경우보다 2배 이상 높게 나타났다.

The suction pressure was measured with respect to operational time by the backwashable flat sheet membrane module in membrane bioreactor (MBR). The membrane module having the nominal pore size of 0.2 ㎛ and the effective membrane area of 128cm2 was submerged in MLSS 8,000 mg/L active sludge aqueous solution. The suction pressure was observed with respect to permeation flux and the quorum quenching (QQ) treatment. The effects of FR and SFCO operation methods were compared and analyzed in the experimental groups: vacant bead (VB), BH4 and DKY-1 beads. The suction pressure reduction was the most effective for the permeation flux 40 L/m2 ⋅h with the injection of DKY-1 QQ beads. Also, the suction pressure reduction by the backwashing method was more than twice for using DKY-1 QQ beads.
