摘要
SO2废气处理是一个棘手而又不得不解决的问题,本文介绍了钠钙法和醋酸钙法吸收二氧化硫的原理和试验方法,试验结果表明钠钙法吸收二氧化硫的速率高于醋酸钙法,吸收后溶液静置所需时间短,静置后上层氢氧化钠溶液可循环使用,且回收利用效率高于醋酸钙法。
It was difficult to treat sulfur dioxide, but the problem must be solved. The principle and the test of ab- sorbing sulfur dioxide by sodium - calcium method and calcium acetate method were intrduced. The results showed that it had quick speed to absorb sulfur dioxide by sodium - calcium method. The standing time of sodium - calcium method was short, and the upper sodium hydroxide solution can be recycled. The reagent recycling of sodium -calcium method was more efficient than that of calcium acetate method.
