摘　　要：在静态条件下 ,进行了以磺化褐煤 (SBC)作吸附剂、还原剂净化含铬废水的实验。研究了含铬废水的pH值、浓度和接触时间等因素对SBC吸附、还原Cr(Ⅵ )的影响 ,确定了SBC净化含铬废水的最佳条件。结合对实际含Cr(Ⅵ )废水的吸附、还原净化处理 ,讨论了SBC对电镀废水处理的可行性。The adsorption and reduction of Cr(VI)ion with sulphnated brown coal(SBC) were invesigated under static conditions. The effects of pH value, contacting time and concentration of waste water on the adsorption and reduction of Cr (VI) ion were reported. The feasibility of treating waste water with SBC was discussed.
