摘　　要：该文从活性炭吸附容量及吸附速度与粒度的关系,以及吸附容量的条件出发,验证了活性炭的粒度与吸附水中有机物的负相关关系：碘值与亚甲蓝值之和与水处理的动态吸附容量的相关关系,从而指出在评价活性炭的吸附性能时,需要考虑其粒度对有机物去除的影响；要用碘值及亚甲蓝值之和,而不是将它们分开去评价活性炭吸附水中有机物的相关性。On the basis of the relation between adsorption capacity and adsorption velocity with particle size of activated carbon and conditionality of adsorption capacity of activated carbon, the negative eon＇elativity between adsorption capacity for organic matter and particle size of activated eabon, and the eorrelativity of the sum of iodine value and methylene blue value, not their separate value of activated carbon with its dynamic adsorption capacity for organic matter were approved in this paper with large amount of test data obtained in treatment of filtered Huangpu River water with activated carbon. It was suggested in evaluation of the adsorption capacity of activated carbon, the influence of its particle size must be considered and the sum of iodine value and methylene blue value, not their separte value must be used.

关 键 词：活性炭 碘值 亚甲蓝值 吸附容量
