用菌体/粉煤灰复合吸附剂吸附阳离子黑，通过单因素实验探究其吸附条件和吸附机理。结果表明，处理模拟阳离子黑染料废水最佳条件为：废水自然pH值6.1，吸附剂投加量2 g/L，搅拌时间5 min，静置时间1 h，此时废水脱色率均在90%以上。吸附剂对阳离子黑的吸附较好地符合Freundlich等温吸附模型，吸附属于单分子层吸附，且吸附过程容易进行。吸附剂对阳离子黑的吸附动力学过程属于Lagergren准二级吸附。

This thesis intends to explore the application of treating cationic black dye wastewater with a new adsorbent compounded with mold/lfy ash. It discussed the adsorption conditions and mechanism of cationic black through single factor experiments. The results showed that the removing rate was above 90%, when the dosage of composite adsorbent was 2 g/L, wastewater natural pH value was 6.1, stirring time was 5 min and standing time was 1 h. The cationic black system iftted Freundlich thermostatic adsorption equation. And the adsorption of cationic black on composite absorbent was easy, and it was monolayer adsorption. While the adsorption kinetic of cationic black system iftted quasi-two adsorption kinetics.
