The techniques of wastewater t reatment in AlF3 indust ry has been studied.The results show that thetechniques of one-step neutralization-sedimentation and 2-step neutralizatio n-sedimentation are not suitable fortreating this kind of wastewater, The most suitable technique is to neutralize the wastewater with excessive limecream and to adjust the pH w ith acids.It is considered applicable to add CaCl2 to the lime cream neut ralization.
Key words： fluoride-containing wastewater; lime cream; fluo ride removal
