- 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。
- Abstract:
- 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.
