| 摘 要： | 通过中试分析了长期运行条件下臭氧—活性炭工艺中溶解性臭氧对活性炭净水效能产生影响的原因。试验条件下活性炭对UV254的去除能力随剩余臭氧浓度的增加而下降。根据试验推测臭氧对活性炭的影响主要体现在3个方面:首先,在臭氧投加量较高时,NOM中亲水性有机物比例增加,此类物质在活性炭上的吸附性较差;其次,臭氧氧化降低了活性炭的吸附能力,同时臭氧可能与活性炭反应生成新的氧化产物;最后,臭氧可抑制活性炭上微生物的生长繁殖。因此建议在臭氧—活性炭工艺运行时严格控制进入活性炭吸附池的剩余臭氧浓度。 |

| Abstract: | Based on the results of a pilot-scale ozone-granular activated carbon(GAC) experiment,effects of dissolved residual ozone on the water purification efficiency of GAC filtration as well as its influence factors were studied.UV254 removal efficiency of GAC filter decreased as residual ozone concentration increased,and the effects of residual ozone on GAC purification efficiency were proved to be mainly derived from the following 3 factors.First,at a relatively higher ozone dosage,a larger portion of NOM was t... |
