摘　　要：饮用水水源中通常存在有致嗅味物质,由于常规饮用水净水工艺对致嗅味物质去除效果不佳,导致饮用水有异嗅异味的问题。试验以水中典型的致嗅味物质二甲基异冰片和土嗅素为嗅味代表物质,研究了凹凸棒土作为吸附剂对嗅味物质的吸附行为,探讨了pH值、凹凸棒土投加量、水力条件、竞争吸附等对凹凸棒土吸附水中嗅味物质的影响。There are some materials in the drinking water resources which can result in taste and odor of water.Traditional drinking water treatment processes cannot remove those material effectively,therefore taste and odor of drinking water is still a big problem which should be resolved.The purpose of this paper is to study the removal of the typical taste and odor chemicals,for example 2-MIB and GSM,in drinking water by attapulgite clay adsorption.Effects of pH value,temperature,and the hydraulic conditions as well as the competition adsorption between 2-MIB and GSM adsorption on attapulgite clay were studied.
