为了处理印染废水,进行了用HCI活化硅藻土,粉煤灰及其处理效能的试验。试验结果表明,活化后的硅藻土和粉煤灰对疏水性染料效果良好,而对活性染料或偶氮染料效果不够理想。
In order to deal with printing and dyeing wastewater, experiments were carried out to activate diatomite, fly ash and their treatment efficiency with HCI. The experimental results show that activated diatomite and fly ash have a good effect on hydrophobic dyes, while the effect of reactive dyes or azo dyes is not satisfactory.
