ABSTRACT

In this study, effluent water was produced through Submerged Membrane Bio-Reactor(SMBR) process, which is a simple system and decomposes organic matter contained in wastewater with biological treatment process and performs solid-liquid separation, Especially, ozone oxidation treatment process is applied to effluent water containing fluorescent whitening agent, which is a trace pollutant which is not removed by biological treatment, and influences the quality of reused water. The concentration of CODCr in the Submerged MBR bioreactor was 449.3 mg/ℓ-CODCr, and the concentration of permeate water was 100.3 mg/ℓ-CODCr. The removal efficiency was about 70.1%. The amount of ozone required for the removal of the fluorescent whitening agent in the permeated water in SMBR was 6.67 g-O3/min, and The amount of ozone required to remove CODMN relative to the permeate water was calculated to remove 0.997mg-CODMn for 1mg of O3.
