卧式/立式倒伞型表面曝气机为垂直轴低速曝气机，可广泛用于城市污水和各种工业废水的生化处理。该机型径向推流能力强、充氧量高、混合搅拌效果好，特别适宜于表曝型氧化沟污水处理工艺。
The Horizontal/Vertical Kind Inverted-Umbrella Surface Aerator are vertical-shaft and low-speed aerator. It can be used in the biochemical treatment of municipal sewage and industrial wastewater. It’s very efficient at propelling water radially, aerating and mixing the water. The inverted-umbrella is especially suited for surface aeration oxidation ditch process.
工作原理
在叶轮的强力推进作用下，水呈水幕状自叶轮边缘甩出，形成飞跃，裹进大量空气；由于污水上下循环，不断更新液面，使污水大面积与空气接触，将空气中的氧气迅速融入污水中，完成对污水的充氧作用，加快污水的净化。同时，强大的动力驱动，搅动大量水体流动，从而实现推流作用。
Working theory:
As the impeller rotates, water is pushed radially and thrown out along the edge of the impeller. As the wastewater continuously gets drawn up from the bottom and through out along the rim, the turbulent water exposed a large surface area to the air, increasing the speed of oxygenation. At the same time, the movement of the waste water by the aerator helps to keep the circulation going in the pool.
