摘要：
主要进行两方面的研究,一是运用Al-Ferron逐时络合比色法考察用经过磁化的水溶解固体聚合氯化铝对聚合氯化铝形态分布的影响,二是考察磁化对液体聚合氯化铝形态分布的影响。研究结果表明,在这两种情况下,都会引起聚合氯化铝形态分布的变化,即:在絮凝过程中起主要作用的Alb的含量得到提高,从而提高絮凝剂的絮凝性能。通过絮凝试验的结果同样证明了磁化可影响聚合氯化铝的形态分布,提高其絮凝性能。

Abstract:
There are two main parts in this article. Al-Ferron timed complex colorimetric method is used to study the effect of the speciation characteristics when solid polyaluminum chloride(PAC) is dissolved in magnetized water and the change of the speciation characteristics when liquid polyaluminum chloride is magnetized. The results show that when solid polyaluminum chloride is dissolved in magnetized water, the concentration of Alb is improved. For the magnetized PAC, the concentration of Alb is improved too. At the same time, the flocculation characteristics of magnetized PAC are studied by jar test. The result shows that magnetization has effect on the speciation characteristics of PAC and improve the flocculation efficiency.
