摘要
试验研究了新型环保絮凝剂APAC对高浊度高岭土废水的重力沉降性能,考察了APAC的盐基度、水体的pH值、絮凝剂的投加量及絮凝剂种类对沉降性能的影响。结果表明:当用盐基度为80%的APAC处理中性水体时,其最佳投加量为10mg/L;与PAC絮凝剂相比,该絮凝剂具有更好的沉降性能。
The gravitational sedimentation characteristics of kaolin wastewater with high - turbidity are studied by adding a novel environment - friendly flocculent APAC. Effects on the sedimentation characteristics of different basicity, the pH value, the dosage and the species of flocculent are investigated respectively. The optimal are obtained as follows ： the basicity is 80%, the pH value of raw - water is 7, the dosage of APAC is Comparing with traditional flocculent（ PAC ）, the sedimentation characteristics of kaolin wastewater were effectively by adding flocculent APAC. conditions 10mg/L. improved
