摘要: 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20.7 mg/L，Cl-为176 mg/L，电导率为387 μS /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。

Abstract: The productive process of vanadium, such as the extraction of metavanadate sodium using a roasting water with low sodium—the purification of ion exchange resin-the precipitation of vanadium through ammonium chloride, produces a great quantity of wastewater with high salinity and poor biodegradability. It is extremely difficulty for the wastewater to meet emissions standard using traditional methods. In this study, an integration technology including "coagulation-sand filtration-activated carbon filter-microfiltration-reverse osmosis" was provided. The optimum conditions of coagulation and sedimentation were investigated. Meanwhile, various factors for the operation of membrane were also studied, including the operating pressure, time and pH. The results showed that the COD in wastewater after reverse osmosis was 20.7 mg/L, the chlorine concentration was 176 mg/L, the conductivity was 387 μS/cm, and the desalination rate was 99.4%. The removal efficiency of heavy metals such as total chromium, Cr(VI) and total vanadium was more than 99%, and the contents of heavy metals in water were much lower than the emission standard in China. This water could be reused for most of the production process. And the concentrate was also applied for the balling process and flue gas treatment. Zero emissions of wastewater in the vanadium smelting wastewater was obtained in this process, and therefore, will provide considerable economic value and broader application.
