摘要

以水玻璃、硫酸铁、硫酸锌和四硼酸钠为原料，通过共聚合合成了一种新型无机絮凝剂聚硅硼铁锌硫酸铁(PSBFZ)。比较了聚合氯化铝(PAC)、聚合硫酸铁(PFS)、聚硅酸铁(PSF)和聚硅酸铁(PSBFZ)的絮凝性能。研究了pH、温度、贮存时间和投加量对絮凝效果的影响。结果表明，PSBFZ具有最佳的絮凝性能。在最佳工艺条件下，浊度去除率达99.6%，色度去除率达99.4%。

Study on the Performance of a Novel Inorganic Polymeric Flocculant

A new type of inorganic flocculant, poly silicon boron ferric zinc sulfate (PSBFZ), was synthesized from sodium silicate, ferric sulfate, zinc sulfate and sodium tetra borate by co-polymerization. Comparative flocculation behaviors among poly-aluminium chloride (PAC), poly-ferric sulfate (PFS), poly silicate ferric (PSF) and PSBFZ were explored. The influences of pH, temperature, storage time and dosage on flocculation were studied. The results demonstrate that PSBFZ exhibits the best flocculation performance. Under the optimum conditions, the removal rate of turbidity and chromaticity were up to 99.6%, 99.4%, respectively.
