Study on Vanadium Solution Dissolved Sediment in Wastewater from Vanadium Precipitation
Using vanadium solution of vanadium production plants back to dissolve sediment in wastewater from vanadium precipitation，the effects of the pH value of vanadium solution, dissolution time, solution temperature on dissolving ability of vanadium solution were investigated, the research results are showed as following: with the pH=10 or more of vanadium solution, dissolution time for 18 min, solution temperature at 60°C, the dissolution of vanadium solution is strongest, the concentration of vanadium in solution increases from 29.5g/L to 65g/L or more. In addition, both composition and specific gravity of the ammonium polyvanadate (APV) are consistent with that of vanadium production plants.
