含汞废水处理

Treatment of Mercury Wastewater

对比了几种汞处理的方法,通过实验室分析总结采用硫化钠沉淀含汞废水效果较好。实验数据结果表明,出水中汞的含量小于国家规定的排放标准沉渣体积小且化学稳定性很好,易处置。此法具有反应速度快,沉淀效率高,可连续处理和间歇处理,处理费用低等优点,该法可在中小型化工厂中推广应用。

Comparison of several methods of mercury processing, through laboratory analysis and summary by sodium sulfide precipitation mercury containing waste water was better. The experimental results showed that the content of mercury in water, less than the national discharge standard sediment volume was small and very good chemical stability, easy disposal. This method had quick response speed, high deposition efficiency, continuous processing and batch processing, low processing costs, etc, and this method can be applied in small and medium -sized chemical plant.
