硫酸亞鐵
硫酸亞鐵
硫酸亞鐵是化學式為FeSO4的無機化合物,又稱黑礬、綠礬外觀為水綠或藍綠色結晶。是在硫酸法生產一種稀有色金屬產品的過程中產出的副產品。硫酸亞鐵是一種常用的絮凝處理劑,在污水處理中起到絮凝處理的效果,可以去除掉污水中大量的懸浮物,去除一部分的cod和脫色。水中加入一定量的硫酸亞鐵可調節堿性水的PH值,硫酸亞鐵與水中的懸浮物有機結合,并迅速沉淀。硫酸亞鐵主要應用于水質凈化和工業廢水處理,同時具有殺菌作用。硫酸亞鐵無水物為白色粉末,與水作用則變為藍綠色。

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.
