摘要
近年来人们发现硫化亚铁清除含镍工业废水效果很好,而煤系中硫铁矿资源丰富,价格低廉,可为含镍工业废水治理开辟新途径。以煤系中硫铁矿和还原铁粉为原料,制备含镍废水净化剂——硫化亚铁,当原料的比例为100∶10,加热温度为200℃,加热时间为10min时对工业废水中的镍去除率较高。
In recent years, people found the effect of ferrous sulfide in nickelic industrial waste water clarifying is quite good. While there is abundant very cheap pyrites resources in coal measures, that is a new path to control nickelic industrial waste water. To use pyrites in coal measures and reduced iron powder as raw materials, prepare the ferrous sulfide clarifier, the best condition of nickel removal is raw material ratio 100：10; temperature 200℃ and heating time 10 minutes.
