TREATMENT OF WASTE WATER CONTAINING IRON CYANOGEN COMPLEX ION

摘要

PURPOSE:To enable easy treatment of waste water with a high degree of efficiency by adjusting pH of waste water to be treated and adding a manganese compound to form a manganese salt insoluble in water. CONSTITUTION:pH of waste water containing iron cyanogen complex ion is adjusted to above 6. Then, an effective quantity of water-soluble, neutral manganese compound such as manganese chloride, manganese sulfate is added to the waste water to produce a manganese salt of iron cyanogen complex compound insoluble in water. The product is removed from the waste water.
