| 摘 要： | 以水中高岭土颗粒和腐殖酸有机物为去除对象,首次采用颗粒计数仪对铝盐絮体的动态絮凝变化过程进行了在线监测和分析。通过改变水力条件和投药量,分析了硫酸铝和聚合氯化铝(PAC)絮凝剂絮凝过程中各阶段的絮体颗粒粒径分布情况,在此基础上分析并确定絮凝反应的最佳条件。通过实验表明:颗粒计数仪能够较好地表现出絮凝过程的粒径分布变化,同时得出颗粒总数变化与絮凝效果的相关性很好,可以灵敏地表征絮凝效果的好坏,因而可以用来优化絮凝剂的投加量,提高出水水质和降低出水成本。可以预期,颗粒计数器在未来水处理中一定会得到广泛的应用。

| Abstract: | The particle counter was used to study the dynamic properties of Al-flocs for the first time, which were formed by Kaolin and humic acid. Particle size distribution of aluminium sulphate and poly aluminium chloride in flocculation process were obtained by changing hydraulic conditions and dosages quantity. The optimum flocculating conditions have been determined. The experiment showed that particle counter can put up the particle size distribution in flocculation process. It was also shown that the particle... |
