Study on surface activity dose of eliminating chromium ion in waste water by using foam flotation method

目的:为找到泡沫浮选法去除废水中铬离子活性较好的表面活性剂,对表面活性剂种类进行探索。方法:对泡沫浮选法去除废水中铬离子的表面活性剂选择进行了研究,实验在间歇式泡沫浮选塔中进行,对阳离子型、阴离子型、非离子型和两性型等不同性质的多种表面活性剂的浮选效果进行了考察。结果:泡沫浮选法去除废水中铬离子的表面活性剂,阳离子型和非离子型表面活性剂效果最差,阴离子表面活性剂效果最好。结论:阴离子表面活性剂十二烷基硫酸钠效果最好。

Objective：To find good activity surface activity dose which eliminating chromium ion in the waste water by using foam flotation method to determine the kinds of the surface activity. Methods-Surface activity dose of eliminating chromium ion in the waste water was determined by using foam flotation method. The experiment was in progress in dyadic foam of intermittence flotation tower, to the positive ion type, the negative ion type, type and amphiprotic type, etc. Various character of surface activity dose flotation effects was determined. Results：Eliminating chromium ion in the waste water was obtained by using foam flotation method and anionic surfactants effect was the best. Conclusion：The SDS has an ideal effect.
