摘  要：以污水污泥為原料，采用物理活化法制得污泥活性炭，并用該活性炭處理染料廢水，研究了pH值、泥活性炭的投加量、溫度、吸附時間等因素對染料廢水的脫色率和COD去除率的影響。結果表明：用污的活性炭,其碘值和亞甲基蘭吸附值分別為254.36 mg/g和20.26 mg/g，具有較好的吸附性能；將污泥活性炭用來吸附氨基黑染料，并與商品活性炭處理氨基黑染料的效果進行對比，自制污泥活性炭的脫色效果達到了商品活性炭的水平；污泥活性炭對氨基黑染料的吸附過程符合Langmuir 吸附等溫線。

 Preparation and decolorization properties of activated carbon fromsewage sludge

Abstract：Activated carbon from sewage sludge was made by physical activation. The effects of pH,carbon amount,temperature and adsorption time on the decolorization of alkaline-black waste water and COD removal rate were investigated. The results showed good adsorption capacity of activated carbon from sewage sludge. The values of iodine and methylene blue were 254.36 mg/g and 20.26 mg/g,respectively. Then activated carbon from sewage sludge was used to adsorb alkaline-black. Decolorization by activated carbon from sewage sludge was similar to commercial activated carbon. The adsorption of alkaline-black followed Langmuir isotherm.
