Abstract:

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.

摘要：

对氟化铝生产废水的处理方法进行了研究。结果表明,一级中和沉淀法和二级中和二级沉淀法均不宜用于氟化铝生产废水的处理,理想的处理方法是碱过量中和酸回调法,辅加氯化钙的石灰乳中和法也可考虑采用。
