摘　　要：由于工业给水处理及饮用水处理大量使用天然水作水源,水中有机物的危害显得十分严重,目前多采用活性炭吸附处理去除水中有机物,这就要选择对水中有机物吸附容量高的活性炭。该文介绍给水处理用活性炭吸附性能指标的研究过程、当前的各种技术观点以及最新研究进展,包括国标提出的水处理用活性炭吸附性能指标(碘值和亚甲兰吸附值),以及用天然水中四种天然有机物(腐殖酸、富里酸、木质素、丹宁)作吸附质来评价活性炭吸附性能,也研究了焦糖脱色率指标。焦糖脱色率指标可以用来很好地表征给水处理用活性炭吸附性能,而且具有指标直观、试验方法简单、便于推广应用等特点。Since nature water, in which organics are harmful to human＇s health, is widely used in industrial water and drinking water treatment as raw water, the process of activated carbon absorption is used to remove the organics in water treatment. In this paper the status of recent research on activated carbon absorption index was introduced. Indexes, including water treatment activated carbon absorption indexes（iodine blue and methylene blue absorption value）, and four kinds of nature organics in natural water（humic acid, fulvic acid, lignin, tannins） were used to evaluate the activated carbon absorption capacity and caramel is also used. Caramel ab- sorption is more suitable to evaluate the absorption capacity and has some advantages as index intuitive, test simple, spread easy, etc.
