摘　　要：为探讨精苯废酸的处理方法,采用窑皮和脱硫渣对精苯废酸进行处理,制得的产物可以用作缓凝剂,利用X射线衍射确定其纯度,探讨了产物掺入熟料中的比例。试验表明,随着产物掺入比例的增加,凝结时间呈直线上升关系。此工艺操作简单、无二次污染,达到了以废治废的目的。In order to discuss treatment method of waste acid from benzol refining, the kiln husk and desulphurization slag were used to treat the waste acid. The reaction production can be used as retarder. Its purity was ascertained through the X-ray diffraction. The test also discussed the proportion of the production to mix to clinker. The results showed that with the increase in the proportion of the production, coagulation time was straight up relations. The process operation was simple, had no secondary pollution and achieved the aim of waste control by waste.
