摘要
以硅酸钠、硫酸铁为原料通过超声的方法制备了无机高分子纳米聚硅酸铝铁絮凝剂(Nano-PFSS),考察了其沉降性能、投加量、pH值、搅拌强度等因素对废水处理效果的影响,并对混凝机理进行了分析.实验表明:Nano-PFSS比普通聚硅硫酸铁处理废水效果更佳.对印染废水的浊度去除率为96.6%,色度去除率为93.2%,CODCr去除率为53.8%.
A new type of flocculant nano-polyferric silicate sulfate （Nano-PFSS） was prepared by ultrasonic waves using sodium silicate and ferric sulfate. The factors influencing the removal efficiency the wastewater, such as settling performance, coagulant dosage of turbidity, pH and stirring intensity were investigated and the coagulating mechanism was also analyzed in this study. The results of the coagulation-flocculation showed that the performance of nano-polyaluminum ferric silicate was much better than experiments for treatment wastewater that of polyaluminum ferric silicate. Used in dyeing wastewater, the removal ratio of turbidity was 96.6%, the removal ratio of decolorizing was 93.2 % and the removal ratio of chemical oxygen demand（CODcr） was 53.8 %.
