| 摘 要： | 以我国南方河网原水中有机物和季节性溴化物(Br-)为对象，研究臭氧-生物活性炭(BAC)工艺净化过程中有机物相对分子质量(Mr)分布变化及溴酸盐(BrO-3)和消毒副产物(THMs)的形成规律.结果表明，原水中Mr在103以下的有机物(DOC)约占总量的80%，常规工艺主要表现为对Mr >100×103有机物的去除，出水DOC去除率为8%、 SUVA(UV254/DOC)值下降14%；臭氧-活性炭工艺主要去除103<Mr<5×103的有机物，但亲水性小分子有机物抑制生物降解作用，出水DOC去除率仅提高至30%、SUVA值下降31%.当臭氧投加量高于2 mg/Ｌ时，臭氧氧化出水中BrO-3增加明显，氧化过程原水中Br-浓度升高BrO-3生成量增大；生物活性炭对BrO-3的去除率平均仅为13%，且波动较大.与常规处理相比，臭氧-生物活性炭处理后各类THMs均有减少，总量减少40%；但氯量和Br-对溴代副产物影响大，主要为CHBr3生成量增加.

| Abstract: | The products of relative molecular weight(M_r) distribution,bromate(BrO~-_3) and trihalomethanes(THMs) were studied by ozone-biological activated carbon(O_3-BAC) process for treating organic matters and bromide(Br~-) in water source of southern brooky regions of China.The experimental results showed that dissolved organic matters(DOC) with M_r lower than 10~3 accounted for 80% of the total.The removal rate of DOC and SUVA(UV_254/DOC) were 8% and 14% respectively by traditional treatment process with main re... |
