Abstract:Treatment of pulping effluent by the suspended carrier biological film -MBR system was carried out, and compared with using the aerobic activated sludge system. The treatment effect and the sludge physic-chemical properties in the suspended carrier biological film-MBR system were better than that of the aerobic activated sludge system during the domestication, especially when high proportion of the pulping effluent was used. CODCr removal efficiency was as high as 90.6%, MLSS was 3876 mg/L, and SVI value was 60.3 mL/g in the suspended carrier biological film -MBR system after domestication. As contrast CODCr removal efficiency was 82.4%, MLSS was 3135 mg/L, and SVI value was 70.3 mL/g in the aerobic activated sludge system. The UV-vis spectrum of the discharged effluent indicated that degradation efficiency of the specific pollutants of 200~300 nm adsorption was higher by using suspended carrier biological film -MBR system than aerobic activated sludge system.
