通过小试和中试研究，研究了絮凝时间和絮体大小对溶解气浮性能的影响，并确定了三种不同类型供水的空气需求量。结果表明，不需要较长的絮凝周期，建议制备10-30um的絮体颗粒进行浮选。检查了两种空气供应测量:循环百分比和气泡体积浓度或每处理体积的水释放的空气体积。4600 ppm或8%再循环的气泡体积浓度足以有效处理所有测试水。 包括24个参考文献、表格和图表。

Bench-scale and pilot-plant studies were used to investigate the effects of flocculation time and floc size on the performance of dissolved air flotation and to determine air requirement for three different types of water supplies. The results show that long flocculation periods are not needed and suggest that floc particles of 10-30 um should be prepared for flotation. Two measures of the air supplied were examined: percentage recycle and the bubble volume concentration or the volume of air released per volume of water treated. Bubble volume concentrations of 4,600 ppm or 8 percent recycle were sufficient to effectively treat all the waters tested. Includes 24 references, tables, figures.
