The optimum aperture of an aerator is smallest at the water depth of 4 m.
一般水深在4 m左右;曝气器的最优孔径最小.
The optimum water depth increases as the aperture of the aerator increases.
水深较小时,宜选用孔径较小的曝气器;
The length of air cavity is an important factor in design of lateral aerator.
摘要侧空腔长度是侧墙掺气坎设计时考虑的重点内容。
Aerator should be generally placed in the center of fishpond, or like windward on the drawing.
增氧机一般应放置在鱼池中央，或图略偏上风的位置。
Frequently clear the attachment on impellers to avoid load increasing, so as to not damage aerator by overload.
应经常清除叶轮附着物，防止负荷增加，以免造成过载运行而损坏增氧机。

曝气机
In project, in order to realize environmental and economic benefits, it’s necessary to select proper sort and quantity of aerator, aerate in condign seasons and fix aerator appropriately avoiding happening sediment suspending.
在工程实践中，要结合环境效益和经济效益，确定水体需氧量，选择合适的曝气设备、数量，在适宜的季节进行曝气，而且要妥善安装曝气机，避免发生底泥悬浮。

掺气坎
At the same time, in engineering practice, after emplacing bucket aerator it will format aerated cavity ,and the hawk for two free surface is the difficulty of calculation.
但在工程实际中,布设掺气坎后会形成掺气空腔,这样对其进行数值模拟就需要同时进行两个自由水面的捕捉,使计算难度更大。
掺气设施
Applying the k - e turbulence model, the distributions of air concentration are predicted for the air-water flow below an aerator. The validity of the numerical solution is demonstrated by the comparison between value measured and calculated.
紊流模型计算了强迫掺气设施后的水气两相流，计算结果与实测值的比较表明，所采用的预测方法是行之有效的。
