摘　　要：活性炭吸附可以作为水处理工艺中的一个单元，它对有机物具有较好的去除能力且有选择性．研究表明，对分子量 ５００以下和 ３ ０００以上的物质．活性炭的吸附能力较差，但对于分子量 ５００～１０００范围内的有机物具有很好的去除能力．同时，活性炭对致突活性物质有长效的去除能力．在实际应用中可根据水中杂质的成分在适当的工艺段选用活性炭处理．Active carbon may act as a unit in the technology of water treatment. It can remove the organic substances effectively. The tests show taht: active carbon's adsorption abilities of the substances whose molecular weight are below 500 and over 3000 are not so good, but has a quite good removal ability of the organic substances whose molecular weight range from 500 to 1000. Active carbon has a long - time removal ability of mutagenic organic substances. In the practical use, active carbon treatment can be desinged bedhind the traditioal treatment techology units.
