摘　　要：以黄河水库水为原水,探究前置式臭氧/生物活性炭流化床作为预处理工艺对净水效率的影响,并与作为末端深度处理的后置式臭氧/生物活性炭工艺进行对比。当采用前置式臭氧/生物活性炭作为预处理工艺时,出水中总有机碳(TOC)、生物可降解溶解性有机碳(BDOC)、氨氮浓度比后置式分别降低了11.8%、12.7%和72.1%,颗粒物数和浊度分别可降至(125±8)CNT/mL和(0.16±0.03)NTU;出水中溴酸盐、甲醛等氧化副产物均满足《生活饮用水卫生标准》(GB 5749—2022)要求。前置式臭氧/生物活性炭流化床和常规处理工艺对污染物的去除具有协同作用,各项出水指标全面优于后置式臭氧/生物活性炭工艺。这可以为微污染原水的高效净化研究和工程实践提供指导。The effect of pre‑type ozone/biological activated carbon(O3-BAC)fluidized bed pretreatment on purification efficiency of raw water from a reservoir in Yellow River basin was investigated,and the treatment performance was compared with the terminal advanced treatment process of post‑type O3-BAC.When the pre‑type O3-BAC process was adopted,the total organic carbon(TOC),biodegradable dissolved organic carbon(BDOC)and ammonia nitrogen(NH3-N)in the effluent were reduced by 11.8%,12.7%and 72.1%respectively compared with those in the effluent when the post‑type O3-BAC process was adcpted,and the particle number and turbidity in the effluent were reduced to(125±8)CNT/mL and(0.16±0.03)NTU,respectively.The oxidation by‑products such as bromate and formaldehyde in the effluent all met the limits specified in Standards for Drinking Water Quality(GB 5749-2022).The pre‑type O3-BAC fluidized bed and conventional treatment process had a synergistic effect on pollutants removal,and all indicators in the effluent were superior to those in the effluent from the post‑type O3-BAC process.The results can guide the development and engineering practice of efficient purification process for micro‑polluted raw water treatment.
