摘　　要：基于国内外研究文献结合自身最新研究工作,论述了去除工业废水中汞离子的化学沉淀法、微电解—混凝沉淀法、吸附法等方法及其作用原理,并分析了各种方法的优缺点;指出了吸附法对含极低浓度汞离子废水的深度处理具有明显的优势。近年来合成的新型导电性聚芳香胺对汞离子初始质量浓度为十至数百mg/L的溶液中汞的去除率在99.99%以上,在含汞工业废水处理中显示出了广阔的应用前景。The methods and their action principles for removing mercury ion from industrial wastewater, such as chemical precipitation, micro-electrolysis-coagulation and adsorption, are summarized based on the literature at home and abroad and the author＇s recent research. The advantages and disadvantages of the methods are analyzed. It is pointed out that adsorption method has an obvious advantage in the advanced treatment of wastewater containing mercury ion with very low concentration. A new type of conductive poly-aromatic amine, which is synthesized in recent years, has shown a mercury ion removal rate of above 99.99% with the initial mass concentration of mercury ion from ten to hundreds mg/L. It shows that the new product has a wide application prospect in the treatment of industrial wastewater containing mercury ion.
