| 摘 要： | 采用复合共聚工艺分别制备了高浓度的聚合硫酸铁硅(PFSS)和聚合硅酸铁(PSFS)，通过实验对影响絮凝效果的因素、絮体沉降特性以及处理后水中残留铁量进行了分析。结果表明，si02含量越高，混凝效果越好，而Fe(Ⅲ)含量需适中，PFSS在Si／Fe比为0.75时效果最佳，PSFS在Si／Fe比为2．0时最佳，高浓度的PFSS和PSFS的絮凝效果优异，pH、浊度适用范围宽，处理后水中的残留铁量少。

| Abstract: | PFSS and PSFS with high concentration were prepared respectively by composite techniques, and some influencing factors, flocs properties and residual Fe content were analysed. The results indicated that the content of SiO2 and Fe(III) greatly influenced the coagulating effects, meanwhile this flocculant has more excellent coagulating effect, widely applicable pH range and turbidity range, lower residual Fe content. |
