摘　　要：考察了聚硅铁(PSF)对腐殖酸(HA)的去除效果及影响因素,并与聚合硫酸铁(PFS)、硫酸铁[Fe2(SO4)3]进行了比较。结果表明,当5<pH<9时,PSF对HA的去除效果最好,且对HA的去除率随PSF投量的增加而增大,去除率可高达85%以上。与传统的混凝剂PFS和Fe2(SO4)3相比,PSF可显著提高对HA的去除效果和絮体的沉降性能。The removal efficiency of humic acid （HA） by polysilicate-ferric （PSF） and the influ- encing factors were investigated and compared with those by polyferric sulfate （PFS） and Fe2 （ SO4 ） 3. The results show that when the pH is 5 to 9, the removal rate of HA by PSF is the best and increases with increasing PSF dosage, which can reach above 85%. Compared with the traditional coagulants PFS and Fe2（ SO4 ） 3, PSF can improve the HA removal efficiency and the settleability of flocs.
