硫酸亚铁
硫酸亚铁
硫酸亚铁是化学式为FeSO4的无机化合物,又称黑矾、绿矾外观为水绿或蓝绿色结晶。是在硫酸法生产一种稀有色金属产品的过程中产出的副产品。硫酸亚铁是一种常用的絮凝处理剂,在污水处理中起到絮凝处理的效果,可以去除掉污水中大量的悬浮物,去除一部分的cod和脱色。水中加入一定量的硫酸亚铁可调节碱性水的PH值,硫酸亚铁与水中的悬浮物有机结合,并迅速沉淀。硫酸亚铁主要应用于水质净化和工业废水处理,同时具有杀菌作用。硫酸亚铁无水物为白色粉末,与水作用则变为蓝绿色。

Ferrous sulfate is green or blue-green crystals,The chemical formula is FeSO4。Ferrous sulfate Is a kind of inorganic compounds。Ferrous sulfate is a common flocculating agents。Ferrous sulfate can demystify sewage in great quantities in the suspended in wastewater treatment。Ferrous sulfate can adjust the water's PH. Ferrous sulfate are mainly applied in water purification and industrial wastewater treatment .It also has Antiseptic effect. When there is no water ferrous sulfate is white, but reaction with water becom blue-green.
