摘要：

Chromium & vanadium-containing waste water and residue from the production of vanadium pentoxide lead to inhibit crops and aquatic plants and harm to human beings, it is significant to remove chromium and vanadium in the waste water and residue. Mixed precipitation process have disadvantages such as high sludge yield, difficult to recover chromium and vanadium, etc. Three major methods to remove the chromium and vanadium in the waste water and residue were reviewed including exctraction, ion exchange as well as trivalent iron process. Development trend of removal chromium and vanadium was also prospected.
