两级石灰沉淀法在高浓度含氟含磷污水处理中的应用
|
摘要
通过对两级石灰沉淀法在东南亚某化工厂污水处理站中的运行情况进行分析,以工程实例验证两级石灰沉淀法在磷酸化工项目中对高浓度含氟含磷污水的处理效果,结果表明:出水水质较好,总体流程简单,操作维护方便,总体费用较低。
Through the analysis of operation situation of the wastewater treatment station in a chemical plant in Southeast Asia with two-stage lime precipitation method,which used to treat high concentration fluorine and phosphate containing wastewater,the case has verified that two-stage lime precipitation method has effective application for treatment of high concentration fluorine and phosphate containing wastewater. The results show that this is a method of good effluent quality,simple process,convenient operation and maintenance and low cost.
