毛竹纤维素基绿色絮凝材料的中试合成及混凝性能评价

In this paper we amplificated the synthesis process on the basis of the previous optimal synthesis process of the eco-friendly bamboo cellulose-based flocculating material and tried to synthesize the flocculating material in pilot scale, then did a series of characterization and evaluated its flocculation performance. In the case of using kaolin suspension as simulated wastewater, the flocculation efficiency of the flocculating material was compared with the conventional commercial flocculant. Meanwhile, the flocculating material was used in papermaking wastewater treatment, we investigated the dosage on the flocculation efficiency. The result shows that the eco-friendly bamboo cellulose-based flocculating material has a great flocculation efficiency of wastewater treatment, the turbidity removal rate of kaolin simulated wastewater is up to 98.9%, the turbidity removal rate of papermaking wastewater is up to 99.9%, the COD removal rate is up to 73.5%.
