摘　　要：生物活性炭(BAC)是饮用水厂使用十分成熟的深度处理工艺,BAC表面微生物挂膜情况是判断BAC启动期、指导工艺运行的重要指标。针对BAC启动期判定,开展长期水质监测(COD_(Mn)、TOC、UV_(254)、pH、DO)和活性炭腺苷三磷酸(ATP)监测中试。结果表明,进出水有机物浓度差和去除率均呈现先下降后上升趋势,不同的季节和水源仅影响转折期出现的早晚(冬、春季:去除率中位值约为55%,稳定时间为40~60 d;夏季:去除率中位值约为60%,稳定时间为20 d左右)。进出水溶解氧消耗量与pH差值、ATP含量之间存在一定正相关关系。同时,建立了模型以判断BAC表面生物膜生长情况,提出了水厂生物活性炭柱启动期判断的新方法。Biological activated carbon(BAC)filter is a mature advanced treatment process applied in drinking water treatment plants.The growth of microorganism attached on BAC surface is an important index to estimate BAC startup period and guide process operation.To determine the BAC startup period,long-term water quality monitoring(monitoring indexes include COD_(Mn),TOC,UV_(254),pH,DO)and activated carbon adenosine triphosphate(ATP)monitoring pilot tests were carried out.The differences of organic matter concentration and removal efficiency in influent and effluent decreased first and then increased.Different seasons and water sources only affected the occurrence of turning point sooner or later.In winter and spring,the median removal rate was approximately 55%,and the startup time was between 40 days and 60 days.In summer,the median removal rate was approximately 60%,and the startup time was approximately 20 days.There was a certain positive correlation between the dissolved oxygen consumption and pH difference and ATP content.In addition,a model was established to evaluate the biofilm growth on BAC surface,and a new method for estimating the startup period of BAC filter in drinking water treatment plants was proposed.
