Pilot-Scale Study on the Impact of Ozone Dosage on O3BAC Process for Advanced Treatment Reservoir Water

  • 摘要: 臭氧投加量是O3/BAC(臭氧/生物活性炭)工艺中的重要参数,直接影响净水效果和处理费用. 试验分别采用预臭氧+常规工艺+生物活性炭工艺(下称工艺Ⅰ)和常规工艺+主臭氧+生物活性炭工艺(下称工艺Ⅱ),以CODMn和浊度的去除率、UV254降幅为评价指标,确定了O3/BAC工艺中最佳预臭氧投加量和最佳主臭氧投加量,并分别对比了臭氧投加前后工艺Ⅰ和工艺Ⅱ对污染物的去除效果. 结果表明:工艺Ⅰ中,最佳预臭氧投加量为0.78mg/L,该预臭氧投加量下CODMn去除率和UV254降幅分别较无预臭氧工艺提高28.8%和43.7%;工艺Ⅱ中,最佳主臭氧投加量为1.20mg/L,该主臭氧投加量下CODMn去除率和UV254降幅分别较无主臭氧工艺提高44.8%和73.3%. 可见,在合适的臭氧投加量下,O3/BAC工艺能够高效去除丹江口水库水中的有机污染物,使水质得到显著改善,投加主臭氧的工艺Ⅱ对污染物的去除效果比投加预臭氧的工艺Ⅰ更好.
