摘要
本文介绍泡沫法净化表面活性废水的效率.探讨提浓效率与原水表面活性物质浓度的关系以及pH值与硬度对提浓效率的影响.
This paper introduces the purifying efficiency of separating surface-active v.-astewater by foam. In the experiments, sodium dodecylsulfate (SDS) was reduced from 31.5-183.0mg/L to 3.4-45.7 mg/L by batch separation, and from 75-200 mg/L to 11.2-65.2 mg/L by continuous separation. Use of a four-stage separation could result in concentration of SDS from 100 mg/L in solution to 20 g in foam.
