摘要
以稻壳为母体,高锰酸钾为引发剂,合成了天然改性阳离子絮凝剂,并通过烧杯实验,从自沉、投加量、水体pH、体积效应、有效时间等方面,探讨了絮凝剂对硅藻土模拟废水的絮凝作用。结果表明,当絮凝剂投加量为2.0g/L、pH为5时,硅藻土悬浊液的除浊率能达到87%。
Natural cationic polymer flocculant was prepared with the parent rice husk, by using potassium permanganate as a redox initiator. Influence of flocculant on simulated wastewater of diatomite were carried out based on a series of beaker setting tests and deposition, dosage, pH, volume and efficient time were discussed. It was proved that turbidity removal for simulated wastewater of diatomite can reach 87%when the dosage of flocculant is 2.0 g/L and pH is 5.
