摘要
对采用石灰和粉煤灰处理高浓度含氟含磷化工废水的方法进行了实验研究 ,考察了石灰用量、搅拌反应时间、接触时间等因素的影响 ,同时确定了粉煤灰的吸附容量。实验结果表明 ,采用石灰混凝沉淀 粉煤灰过滤工艺处理高浓度含氟含磷化工废水 ,处理后氟、磷及其他各项指标均达到国家排放标准。
The method treating high concentrated chemical wastewater containing F and P by lime and powder coal ash was reserched. The effect of lime quantity, stirring reaction time and contact time was investigated. The capacity of powder coal ash was determined at the same time. The test result showed that treating High Concentrated Chemical Wastewater by lime Coagulating precipitation-powder coal ash filtering, the F and P and other targets of the treated water all accorded with the discharging standard wastewater in China.
