| 摘 要： | 针对中置曝气生物活性炭工艺进行中试研究,分析在不同的曝气气水体积比下,该工艺对南方某水厂水源的净化效果,并与中置臭氧-生物活性炭工艺的净水效果进行对比。研究表明,对于中置曝气生物活性炭工艺,曝气气水体积比为0.2最合适。在此条件下,炭滤池对浊度、CODMn、UV254、氨氮的去除率分别为54.17%、47.40%、49.40%、84.62%。该工艺对污染物的去除能力比中置臭氧-生物活性炭工艺更好。

| Abstract: | Pilot test was implemented on account of mid-positioning aeration-BAC process,water purification effects by that process with different aeration gas-water ratio were compared at each other and with that by mid-positioning O3-BAC process.Studies showed that: For mid-positioning aeration-BAC process,aeration gas-water ratio as 0.2 was the best.On that condition,average removal rates of turbidity,CODMn,UV254 and NH4+-N by aeration-BAC filter were 54.17%,47.40%,49.40% and 84.62% respectively.And removal effect on pollutants by mid-positioning aeration-BAC process was better than that by mid-positioning O3-BAC process. |
