| 摘 要： | 阐述滤床熟化的概念及其形成机理,对影响熟化床层的因素进行了试验研究,结果表明进水浊度、混凝效果及洗砂量是影响熟化床层的主要因素。由于集成型给水处理设备的表面滤层一直处于熟化状态,而滤层水流方向的深处滤料始终处于清洁状态,砂滤器内始终保持一种动态的平衡关系,滤床运行在熟化后的有效过滤期,因而能够保证较高的出水水质。

| 关 键 词： | 滤床熟化 进水浊度 混凝效果 洗砂量 有效过滤期 |

| Abstract: | It was expounded the concept of aging of a filter bed and its formation mechanism,the factors impacting the aging of the bed were studied,the results showed that the water turbidity,and coagulation effects,and washing sand were the major factors impacting the filter beds aging.Because the integration feed water treatment equipment's superficial filter bed has been at the aging condition,but the filter bed current of water direction's deep place filters the material to be at the clean condition throughout,sa... |

| Keywords: | filter beds aging water turbidity coagulation effect washing sand effective filter period |
