| 摘 要： | 通过规模为200L·h-1的连续动态实验,研究了臭氧预处理对砂滤出水浊度、颗粒数以及运行周期的影响.实验结果表明,投加低剂量0.12mg·L-1的臭氧,就可以显著改善砂滤的运行性能.臭氧预处理可以使砂滤出水浊度和粒径范围为3～7μm的颗粒物(与隐孢子虫大小相当)含量分别从平均0.25NTU和584个mL-1下降到0.05NTU和72个mL-1,其它粒径范围的颗粒数也显著下降,砂滤周期延长了1倍. |
| 关 键 词： | 预臭氧 砂滤 浊度 颗粒 过滤周期 预臭氧 砂滤 过滤性能 影响 performance filter sand 延长 运行周期 含量 大小 隐孢子虫 颗粒物 粒径范围 运行性能 改善 低剂量 投加 结果 动态实验 |
