摘要
硫是煤中的有害元素,煤在燃烧过程中,煤中的硫通常生成SO2而排入大气中,从而导致大气污染。但SO2也是一种较强的还原剂,并且易溶于水。而应用高硫煤燃烧中产生的二氧化硫还原废水中六价铬,可以达到以污治污的目的。
Sulfur in coal is a toxic element which can lead to air pollution during coal combustion. Sulfur dioxide is a powerful reducing agent is easy to dissolve in water. Suliur dioxide can reduce chromium,so it can decrease chromium pollution.
