摘　　要：以城市污水处理厂活性污泥为原料,在其中加入粉煤灰,在不同温度下制备活性污泥-粉煤灰混合吸附剂,对比不同温度下吸附剂的吸附性能,测其对亚甲基兰印染废水的吸附容量,得吸附等温线。结果表明:在300℃下配比为9∶1的吸附剂吸附效果最好,其最大吸附容量为37.49 mg/g。Taking activated sludge which in the urban sewage treatment plant as the raw material, and adding the fly ash, the activated sludge-fly ash mixed absorbent was prepared at the different temperature. Compared the adsorption properties at the different temperature, and measured the adsorption capacity to the methyl radical blue printing waste water, then got the adsorption isothermal. The result indicated that the adsorption effect is best when the temperature is 300 ℃ and the allocated proportion is 9：1, the biggest adsorption capacity is 37.49 mg/g.
