Abstract:

Activated carbon is a regular substance for rejecting organisms,no matter when it is used in the treatment of industrial water or domestic drinking water. But there have been no literature about howto make the pretreatment of activated carbon. Five kinds of frequently used activated carbon,including fruit shell carbon,coconut shell carbon and coal quality carbon,are compared regarding whether acid treatment is needed or not. The results show that activated carbon acid pretreatment can improve its adsorption performance of organisms in water.

Key words: activated carbon, pretreatment, adsorption of organisms

摘要：

无论是在工业用水还是生活饮用水的处理中,活性炭都是一种常规的去除有机物的方法。但活性炭在使用前如何进行预处理却无相关的研究资料,作者将水处理中常用的5种活性炭,包括果壳炭、椰壳炭、煤质炭进行酸预处理对比,试验证实,酸预处理后可以提高活性炭对水中有机物的吸附性能。
