为解决电解锰渣的污染问题,采用Na_2S、生石灰、粉煤灰为稳定剂,水泥为固化剂,对锰渣进行固化/稳定化处理,研究锰渣中Mn、Pb的稳定化效果。结果表明：当稳定剂Na_2S投加量为1.25%,生石灰2.5%,粉煤灰3%,固化剂水泥投加量为12%时,固化/稳定化效果最佳,Mn、Pb的浸出浓度分别为0.022mg/L、0.019mg/L,符合GB3838-2002Ⅲ类标准。

In order to solve the pollution problem of electrolytic manganese residues,Na2S,quicklime and fly ash are used as stabilizers,cement is used as curing agent to solidifies/stabilize manganese residues,and the stabilization effect of Mn and Pb in manganese slag is studied.The results of single factor experiment and orthogonal experiment shows that when the dosage of stabilizer Na2S is 1.25%,quicklime is 2.5%,fly ash is 3%,and curing agent cement dosage is 12%,the solidification/stabilization effect is the best.The leaching concentrations of Mn and Pb were 0.022 mg...
