摘要
The present invention is directed to a process for treating wastewater which comprises producing a ferric hydroxide suspension directly by electrolysis of the wastewater to precipitate heavy metals and organic or inorganic suspended solids thus purifying the wastewater. The purified wastewater, which is a saturated aqueous solution of calcium sulphate, can be recycled for further treatment and production of a low sulphate ferric hydroxide suspension. The process of the present invention is suitable for treatment of wastewaters obtained from mine tailings dams, metal mine pits, etc. and avoids the problems and difficulties of the known processes.
