摘要
以黄浦江原水为研究对象,对臭氧-生物活性炭(O3-BAC)组合工艺去除有机污染物的性能、机理进行了中试研究。结果表明,该工艺对各指标的去除率为:CODMn 24%,UV25435%,三卤甲烷前体物31%,AOC 63%,且对各分子量区间的有机物的去除有互补性。O3-BAC组合工艺一方面可以有效去除黄浦江原水中的微量有机污染物、消毒副产物前体物,减少后加氯量,降低消毒副产物生成量,保障饮用水的化学安全性;另一方面能明显降低水中的可同化有机碳(AOC)浓度,提高饮用水的生物稳定性。
A pilot study was done on the mechanism and performance to remove pollutants using ozone-biological activated carbon （O3-BAC） process. The results showed that removal rates were 24% for CODMn, 35% for UV254, 31% for trihalomethane formation potential, and 63% for AOC. Moreover, the process had a broad-spectrum effect in removing organic matter with various molecular weight distributions. On one hand, the O3-BAC process can effectively remove organic pollutants and disinfection by-product precursors, reduce chlorine dose, and decrease disinfection by-products, to ensure chemical safety in drinking water. On the other hand, the O3-BAC process can remarkably reduce the concentration of assimilable organic carbon （AOC）, to enhance biological stability in drinking water.
