本文介绍了两种澄清/过滤处理装置的颗粒去除结果，并研究了预氧化对工艺性能的影响。当臭氧被用作预氧化剂时，通过过滤器加强对颗粒物的去除，这是臭氧相对于氯、二氧化氯和高锰酸钾的一个显著优势。在氯和二氧化氯的情况下，预氧化似乎会恶化通过澄清器的颗粒去除。澄清池中的颗粒去除不受预分区或高锰酸钾添加的影响。与其他氧化剂和未经预氧化的实验相比，预分区/过滤水中的颗粒浓度降低了一个数量级以上。 无论预氧化剂类型如何，通过使用管沉降器或超脉冲发生器进行澄清，可以去除大约1.5 log的贾第鞭毛虫大小的颗粒。

This paper presents the results of particle removal by two clarification/filtration treatment trains and investigates the effect of preoxidation on process performance. The enhanced removal of particles across the filters, when ozone was used as the preoxidant, was a significant advantage of ozone over chlorine, chlorine dioxide and potassium permanganate. In the case of chlorine and chloride dioxide, preoxidation appeared to worsen particle removal through the clarifiers. Particle removal in the clarifiers was not affected by preozonation or the addition of potassium permanganate. The concentration of particles in the preozonated/filtered water decreased by more than one order of magnitude as compared with other oxidants and experiments conducted without preoxidation. Approximately 1.5 log removal of Giardia-size particles was achieved through clarification, using either the tube settler or Superpulsator, regardless of preoxidant type.
