| 摘 要： | 为解决净水工艺中剑水蚤的二次繁殖问题,进行了生产性试验,考察了二氧化氯与常规工艺协同对剑水蚤的去除效果.指出滤池滞水区停留时间长、流速低是造成剑水蚤二次繁殖的主要原因.二氧化氯预氧化可以强化常规处理工艺对剑水蚤的去除,当二氧化氯投加量为2 mg/L时,可以有效控制剑水蚤的二次繁殖.

| Abstract: | Pilot plant experiments were conducted to investigate the problems of second propagation of Cyclops in waterworks and the combined removal of Cyclops by chlorine dioxide pre-oxidation with routine water purification process. It was believed that the primary reason of the second propagation of Cyclops was the low filtering velocity and the long retention time in the filters. The experimental results showed that the removal of Cyclops was strengthened by routine water purification process plus chlorine dioxide pre-oxidation. The second propagation of Cyclops could be totally controlled when the dosage of ClO_2 was 2 mg/L dioxide. |
