摘　　要：利用凹凸棒复合滤料为填料,研究曝气生物滤池对微污染水源水预处理的挂膜启动特性。研究结果表明:凹凸棒曝气生物滤池25天左右挂膜成功,CODMn和NH3-N去除率分别可达30%和65%,NH3-N的去除率可以作为曝气生物滤池挂膜成功的标志;能谱分析结果显示滤料表面碳含量为12.1%,8.86%来源于滤料吸附的有机物,3.24%来源于滤料表面附着的微生物,能谱分析法是一种评价生物量的有效辅助工具。The start-up characteristic of biological aeration filter to the pretreatment of micro-polluted water was studied with attapulgite composite filter material.The results showed that attapulgite biological aeration filter succeeded after 25 days.The removal rate of CODMn and ammonia-N could achieve 30% and 65% respectively.The removal rate of ammonia-N was used as a symbol for its success.Energy spectrum analysis showed that carbon element of attapulgite composite filter material＇s surface was 12.1%,which organic adsorption from water was 8.86% and adherent microorganism on filter material＇s surface was 3.24%.Energy spectrometer method could be an effective evaluation of biomass auxiliary tool.
