摘要
将太原市杨家堡污水厂初沉污泥（编为１＃）、剩余污泥（２＃）及分别加工（炭化——活化）后所得产物（Ａ＃和Ｂ＃）用作吸附剂（“炭”）对污水进行处理，发现这四种“炭”除了对ＮＨ３－Ｎ几乎都无作用外，对ＣＯＤ、Ｆ－及Ｃｄ２＋都有不同程度的去除能力。当投“炭”量为１～６ｇ／Ｌ时，Ａ＃对ＣＯＤＣｒ的去除率相应达３８～７０％。
Wastewater was treated in laboratory by a process with each one of four sludges:sludge from primary sedimentation tank(No.1),excess activated sludge(No.2)and their two variant types each processed by carbonization and activation(Nos.A and B). Experiments demonstrated that all the four sludges can remove COD、F - and Cd 2+ ions to a varying extent,except little or no effect on NH 3-N.When dosing 1 to 6 g/L,No A sludge(activated sludge carbon)had a COD removal efficiency of 38～70%.
