| 摘 要： | 通过正交实验确定了最佳粉煤灰的活化改性条件：焙烧温度为300℃，Na2CO3加入量为20g，硫酸浓度为70％。将此条件下活化的粉煤灰用于含油废水的处理，在温度为20--25℃，pH值近中性，慢速搅拌时间10min，活化粉煤灰投加量为50g／500mL，含油废水中的COD去除率可达到68．59％，去除效果与活性炭相当，实现了“以废治废”的目的。

| Abstract: | Abstract： Activation of fly ash modified conditions determined by orthogonal experiments： calci- nation temperature of 300 ℃, addition amount of Na2CO3 20 g activation, activated sulfuric acid concentration of 70%. These conditions of activated fly ash are used for the treatment of oily wastewater, the temperature being at a temperature of 20 to 25℃, pH value near neutral, slow stirring time of 10 min, activated fly ash dosage of 50 g/500 mL, oily wastewater COD removal rate can reach 68.59%, removal efficiency of activated carbon equivalent reached by ＂waste used for waste purpose＂. |
