摘要
用氯化三甲基壳聚糖季铵盐(I)作絮凝剂处理造纸废水,Ⅰ在pH值8-13时,COD去除率可达75%以上;Ⅰ较高浓度时的絮凝效果优于低浓度时,适当延长缓慢搅拌时间,能提高Ⅰ絮凝效果;助凝剂的加入,可加速絮凝及提高絮凝效果。
Trimemthyl chitosan chloride quate rnary ammonium as flocculant is used to treat paper -making sewage.When ph Value is betwe en 8and 13,the removal rate of COD reaches 75%;Flocculation can be improved with high concentration of I and longer vibrating time.Co agulant acid speeds up and improves flocculation.
