摘要 分别研究了空气催化氧化法、双氧水氧化法和漂白粉氧化法对脱硫用电石渣浆液中硫化物的去除效果。实验结果表明,在适当条件下,空气氧化法可在240 min内使硫化物的去除率达到80%,适量的双氧水和漂白粉能够使硫化物降至0.5 mg/L以下,去除率达到99%以上。在此基础上对比了3种工艺的经济成本:空气催化氧化法<漂白粉氧化法<双氧水氧化法。 The removal effect of sulfide from carbide slag slurry for desulfurization by three processes,including catalytic air oxidation, H2O2 oxidation and chlorinated lime oxidation, has been studied. The results show that under appropriate conditions the removing rate of sulfide reaches 80% within 240 min by air oxidation process. The sulfide removing rate can be higher than 99%, by using appropriate amount of H2O2 and chlorinated lime. Based on these studies, the economic costs of the three processes are contrasted. It is found that the economic cost of catalytic air oxidant process is less than that of chlorinated lime oxidation process and the cost of chlorinated lime oxidation process is less than that of H2O2 oxidation process.
