摘要
本文对石灰处理含磷废水的传统工艺进行改进,利用石灰粉分阶段与含磷废水反应,减少约30%石灰用量,同时制备得到满足工业磷酸氢钙要求的产品,工艺流程清晰、操作简便,为磷肥企业含磷废水的处理利用提供一定参考。
In this paper,the traditional process of lime treatment of phosphorous-containing wastewater was improved,lime powder was used to react with phosphorous-containing wastewater in stages,reducing lime consumption by about 30%,and products meeting the requirements of industrial calcium hydrogen phosphate were prepared at the same time.
