| 摘 要： | 聚硅酸铝铁是一种新型无机高分子絮凝剂，因其高效的混凝性能，使用条件宽，药剂用量小，残留浓度低而受广泛关注。通过调节Na2SiO3·9H2O、AlCl3·6H2O、Fe（SO4）2-7H2O的量来测定不同条件对PSAF混凝能力的影响，实验结果表明最佳条件为：室温、SiO2为2．0％、（Al＋Fe）／Si为3：1、Al／Fe为1：1。用此条件下合成的PSAF处理印染废水，色度、CODcr、浊度的去除率分别98．8％，81．5％，98．3％，对太湖水的藻类去除率为92％，PASF的絮凝效果明显好于市售聚合氯化铝。

| Abstract: | The novel inorganic ion-flocculant polysilcate aluminum ferric(PSAF) flocculants is prepared from sodium silicate,ferrous sulfate and aluminum chloride.Optimum reaction conditions are investigated and found that the polymerization temperature is room temperature,the concertration of SiO2% is 2.0,the optimum molar ratio of(Al+Fe) to Si and Fe to Al is 3 and 1,respectively.The application of PSAF in the process of dying waste water treatment was studied experimentally.As the results that PSAF has the advantag... |
