用 MnO2脱除电厂烟气中 SO2制取工业硫酸锰的研究

摘要

With MnO2 to remove power plant gas in sulfur dioxide,we have got Mn sulfate solution that can take out industrial level Mn sulfate,with its reaction product residue in Mn≤2.5%,Mn recovery >94% and emissions exhaust in SO2≤0.015%.All can reach standard level,with no emissions wastewater.%用二氧化锰脱除电厂烟气中的二氧化硫，试验得到的硫酸锰溶液可以制取成工业级硫酸锰，反应产物残渣中含锰≤2．5％，锰回收率＞94％，排放尾气中 SO2含量≤0．015％，可达标排放，整个过程没有排放废水。
