摘要: Recovery of phosphates from ferrous and /or ferric residues as a result chemical precipitation was investigated. The product biological reduction sulphates – sulphides free hydrogen sulphide can react with iron ions forming which are less soluble then phosphates, releasing into solution. Laboratory scale experiments have confirmed the possibility recovery. It found that strict anaerobic conditions required process is COD/S ratio dependent.
