IMPROVEMENT OF APV RECOVERY IN THE V₂O₅SHOP PANZHIHUA IRON AND ATEEL Co.

In order to solve the problem existed in the precipitation Stage of V₂O₅ Shop,Panzhihua Iron and Steel,the solubility of APV was investigated,main cause why the vanadium loss is large is found out and the prodution process was improved. The waste water containing solid APV from the precipitation of APV is treated by means of PE sintered microporous filter. The vanadium recovery is increased and the environmental pollution is reauced.
