摘要
介绍了利用盐酸酸洗废液为原料制备复合亚铁絮凝剂的方法 ,研究了复合亚铁的除浊性能 ,考察了硅铁比、水样pH和温度对其混凝性能的影响 ,探讨了其电导性质 ,并应用于印染废水的混凝处理。结果表明 ,复合亚铁絮凝剂效果好、处理成本低 ,值得推广应用。
A process to make compound ferrous coagulant by waste pickle containing hydrochloric acid as raw material was introduced to treat printing and dyeing wastewater, and the property of turbidity removal, effect of Si/Fe, pH and temperature of wastewater on flocculation, electrical conductivity of coagulant were also discussed. Results showed that compound ferrous coagulant was worth applying for its cost effectiveness.
