Abstract:

针对在“低钠焙烧水浸提取偏钒酸钠-离子交换树脂提纯-氯化铵沉钒”生产钒工艺下产生的废水的高盐度,可生化性差,使用传统的方法难以达到排放标准等特点,提出了“混凝-砂滤-活性炭过滤-微滤-反渗透”集成技术处理钒冶炼废水。考察了混凝沉淀的最佳条件,同时重点探讨了操作压力、运行时间和pH等操作参数对膜运行效果的影响。反渗透出水的COD为20.7mg/L,Cl-为176mg/L,电导率为387μS/cm,除盐率达到99.4%,总铬、六价铬和总钒等重金属的去除率都达到99%以上,远远低于国家规定的排放标准,该出水能回用于大部分生产工序;浓缩液也能回用于成球工艺和烟气处理工序,实现了钒冶炼废水的零排放。具有比较可观的经济价值和广阔的应用前景。
