酸性氯化亚铁废水的处理与资源化研究
Treatment and Utilization of Acidic Ferrous Chloride Wastewater
摘要
Abstract
Complex extraction and precipitation methods were applied to remove heavy metal elements zinc and lead from ferrous chloride wastewater of wire rope industries.The main forms of metal ions in the wastewater system were analyzed.Certain factors that affected the treating efficiency were also discussed. The optimized conditions were obtained when the concentration of extractant YF1 was 0.5 mol/L,oil-water ratio was 0.4: 1,Zn2+ would transferred into back-extraction water in the form of Zn(OH)24 when NaOH liquor (1 mol/L) was selected as back-extraction agent.The mechanism of extracting zinc by YF1 was also studied and the extracted complex was consist of (YF1 )2 · H2ZnCl4.The best volumes ratio of lead precipitation YF2 (0.5 mol/L) and the wastewater was 0.04:1.The concentrations of heavy metal zinc and lead in the ferrous chloride solution were both reduced to below 10×10-6.关键词
