【摘要】 采用悬浮填料生物膜-MBR系统处理制浆中段废水,并与好氧活性污泥系统进行了对比。驯化过程中,尤其是制浆中段废水所占比例较高时,悬浮填料生物膜-MBR的处理效果和污泥理化特性均明显优于好氧活性污泥系统。驯化结束时悬浮填料生物膜-MBR系统COD_Cr去除率高达90.6%,悬浮液固形物浓度（MLSS）达到3876 mg/L,污泥体积指数（SVI）为60.3 m L/g,而好氧活性污泥系统COD_Cr去除率为82.4%,MLSS为3135 mg/L,SVI为70.3 m L/g。对出水的紫外扫描结果表明,悬浮填料生物膜-MBR系统对200³00 nm波长处特征污染物的降解效果明显优于好氧活性污泥系统。更多还原

【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. COD_Crremoval efficiency was as high as 90. 6%,MLSS was 3876 mg/L,and SVI value was 60. 3 m L/g in the suspended carrier biological film-MBR system after domestication. As contrast COD_Crremoval efficiency was 82. 4%,MLSS was 3135 mg/L,and SVI value was 70. 3 m L/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.更多还原
