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[Fe_2(SO_4)_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Fe_2(SO_4)_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-ferrie (PSF) and the influencing factors were investigated and compared with those by polyferric sulfate (PFS) and Fe_2(SO_4)_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 Fe_2(SO_4)_3, PSF can improve the HA removal efficiency and the settleability of flocs.
