1·Oils: skimming, emulsion breaking, dissolved air flotation, etc.
油类：撇油，破乳，气浮，等等。
2·To enhance the effect of water purification, the system of pressurized dissolved air flotation was optimal in design.
采用一套自主开发研制的加压溶气气浮装置，对养殖水体中的微颗粒进行净化。
3·The aeration flotation process is a new application to the activated sludge processes. The final tank USES dissolved air flotation instead of sedimentation, and is combined with the aeration tank.
曝气气浮池是活性污泥法中的一种新型构筑物，它是以气浮代替沉淀，并与曝气池有机组合而成。
4·The feasibility, mechanism and the treatment result of adopting the dissolved-air flotation to treat the wastewater containing heavy metals were investigated.
研究了用气浮法处理含重金属废水的可能性、原理及处理效果。
5·A study on thickening waste activated sludge was carried out in a pilot-scale dissolved-air flotation unit. Thickening process curves in different operational parameters were obtained.
通过中型试验研究，获得了在不同运行参数情况下的活性污泥气浮浓缩过程曲线；
