  • 摘要: 为了考察多相芬顿-活性炭工艺对饮用水中微生物消毒效果的影响，采用中试对活性炭工艺与多相芬顿-活性炭工艺进行了对比研究。该中试对水中溶解性有机物(DOC)、总细菌16S rRNA、三磷酸腺苷(ATP)及胞外多聚物(EPS)含量与性质进行了分析。结果表明，多相芬顿-活性炭工艺能够将出水DOC浓度控制在(0.90±0.11) mg·L-1，并使得EPS减少83.2%，降低EPS中蛋白质/多糖(PN/PS)比值，其凝聚性明显下降，在相同氯浓度投加情况下水中微生物16S rRNA基因拷贝数去除量提高了3.5个对数量级，ATP浓度降低为0.016 nmol·L-1。因此，多相芬顿-活性炭工艺明显提高了对有机物的去除能力，显著降低EPS中蛋白质的含量，使得微生物凝聚性变差，微生物更加容易被消毒剂灭活，该工艺强化了饮用水消毒效果。
    Abstract: In order to investigate the effect of heterogeneous Fenton-activated carbon process on the disinfection of microbes in drinking water, the treatment processes of activated carbon filtration and heterogeneous Fenton-activated carbon filtration were studied in a pilot scale. The concentrations and properties of dissolved organic carbon (DOC), 16S rRNA, ATP and extracellular polymeric substances (EPS) were analyzed. The results showed that the DOC concentration in effluents of heterogeneous Fenton-activated carbon treatment process was (0.90 ±0.11) mg·L-1. This heterogeneous process could lead to EPS reduction by 83.2%, the decrease of EPS protein/polysaccharide (PN/PS) ratio, and an obvious decrease of microbial EPS coagulation ability. Under the same concentration of chlorine addition, the removal of 16S rRNA gene copies increased by 3.5 logarithmic order of magnitude, and the ATP concentration decreased to 0.016 nmol·L-1. Therefore, when the heterogeneous Fenton-activated carbon treatment process was used, the organic matter removal was significantly improved, and the content of proteins in EPS was remarkably reduced, and the coagulation ability of microbes was weakened, then they were easily inactivated by disinfectant. This treatment process enhanced the disinfection efficiency.
