| 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。

| Abstract: | 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 conditions are obtained as follows: the basicity is 80%,the pH value of raw-water is 7,the dosage of APAC is 10mg/L.Comparing with traditional flocculent(PAC),the sedimentation characteristics ... |
