摘要
以氯化铝和硅酸钠为原料,制备聚合硅酸氯化铝。通过对影响絮凝效果因素的讨论,优化出除色除浊等效果良好的絮凝剂,并将其应用于板纸厂废水的处理。结果表明:CODcr的去除率可达78%,浊度和色度的去除率可达到90%以上,絮凝效果较好。
Polysilicic-Aluminum Chloride(PASC)was prepared from Na_2SiO_3·9H_2O and AlCI_3·6H_2O under given circumstance. Through discussing on the factors affecting flocculation result of PASC flocculant, the optimum operational conditions were established to remove CODcr, color and turbidity effectively.
