摘要
研究了以劣质铁尾矿为原料制备高效混凝剂聚硅酸铝(PSA)的方法,确定了合理的生产工艺和操作条件。用该混凝剂处理工业废水,并与传统混凝剂进行了比较,结果表明,PSA混凝剂处理效果好,用药量少。
A new preparation method of high efficiency coagulant of polyaluminum silicate(PAS) from poor quality ferric tailings was studied and the reasonable production process and operating conditions were determined. The coagulant was tested in industrial wastewater treatment and compared with traditional coagulant. The experimental results show that PAS has better coagulation property than the traditional coagulant, and the dosage of PAS is less.
