针对酸性铝盐沉钒工艺沉淀酸性铵盐过程中沉钒液内涌起泡沫影响正常操作等问题，考察了钒渣碱地、浸出液ｐＨ值、表面张力和沉钒上层液等影响因素，并提出了相应的改进措施．
In view of the normal operation and other problems caused by the foam in the sinking vanadium solution during the precipitation of acidic ammonium salts by the sour vanadium precipitation process, the influencing factors such as vanadium slag alkali, pH value of the leachate, surface tension and the precipitated vanadium solution were investigated. The corresponding improvement measures.
