| 摘 要： | 阐述了气水混合室气浮装置的工作机理。在实验室条件下确定了试验模型的处理效率，试验模型对石油类物质和固体悬浮物（SS）的去除率达到95％以上。并对试验数据进行了分析，讨论了气水混合室式气浮装置的去除率与转速的关系，达到最佳转速之前去除率随转速的增加而增加，达到最佳转速之后去除率随转速的增加而降低。同时得到了估算最佳转速的经验公式。

| Abstract: | The mechanism of a new air flotation equipment with an air water mixing chamber is explained. The removal efficiency of the equipment is determined under experimental conditions. For substances such as petroleum and suspended solids(SS), the removal efficiency is more than 95%. The experimental data are analyzed, and the relationship between the removal efficiency of the equipment and the rotational velocity is discussed. It is found that the removal efficiency increases with the rotational velocity before arriving at an optimal rotational velocity, and decreases over the optimal rotational velocity. Meanwhile, an empirical formula for evaluating the optimal rotational velocity is obtained. |
