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 。
The techniques of wastewater treatment in AlF 3 industry has been studied. The results show that the techniques of one step neutralization sedimentation and 2 step neutralization sedimentation are not suitable for treating this kind of wastewater, The most suitable technique is to neutralize the wastewater with excessive lime cream and to adjust the pH with acids.
