摘　　要：采用聚合氯化铝铁(PAFC)与微生物絮凝剂(MBF)复配絮凝技术作为超滤工艺的预处理单元,考察该组合工艺对微污染水库水的处理效能。结果表明,MBF与PAFC复配可有效改善絮凝效能,进而提高后续超滤工艺对污染物的去除效果;当PAFC和MBF的投加量分别为3和0.1 mg/L时,组合工艺对CODMn的去除率为41.8%,比单纯采用PAFC时提高了6.6%,对嗅味物质土臭素的去除率在64%左右;另外,组合工艺可将三卤甲烷前体物含量由116μg/L降低到62.3μg/L,去除率为46%。Polyaluminum ferric chloride （PAFC） was combined with microbial flocculant （MBF） to be used as a pretreatment unit of the ultrafiltration process. The performance of the combined process for treatment of micro-polluted reservoir water was investigated. The results showed that flocculation efficiency could be effectively improved by combining MBF with PAFC. When the dosages of PAFC and MBF were 3 mg/L and 0. 1 mg/L respectively, the removal rate of CODMn by the combined process was 41.8% , which was increased by 6.6% compared with using PAFC only, and the removal rate of geosmin was about 64%. In addition, trihalomethane precursors could be reduced from 116 μg/L to 62.3 μg/L by the combined process and the removal rate was 46%.
