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。
A pilot study was conducted on the central aeration biological activated carbon process to analyze the effect of the process on the purification of a water plant in southern China under different aeration gas-water volume ratios, and to achieve the water purification effect of the central ozone-biological activated carbon process. comparing. Studies have shown that for a central aerated biological activated carbon process, the volumetric ratio of aeration gas to water is 0.2. Under these conditions, the removal rates of turbidity, CODMn, UV254, and ammonia nitrogen in the charcoal filter were 54.17%, 47.40%, 49.40%, and 84.62%, respectively. The process has better removal of contaminants than a mid-stage ozone-biological activated carbon process.
