  • 摘要: 以模拟甲基紫染料废水为处理对象,通过测定絮凝R值、Zeta电位、脱色率与CODCr去除率,研究了自配铝铁改性淀粉复合絮凝剂(CAFS)的絮凝特性,初步探讨了其絮凝机理.结果表明,该复合絮凝剂为阳离子型高分子絮凝剂,絮凝初期作用机理趋于"吸附电中和",絮凝后期作用机理以"絮凝架桥"和"卷扫网捕"为主,絮凝性能受pH值影响显著.在pH=11.0,投加量为0.330 mg·L-1时,甲基紫处理效果最优,CODCr去除率达41.0%,色度去除率高达98.0%,其絮体形态密实、含水率低.
    Abstract: A combined flocculant (CAFS) was prepared with aluminum sulfate, ferrous sulfate and starch, and the flocculation mechanism in the methyl violet solution was studied using continuous optical monitoring, Zeta potential measurement, CODCr measurement, color measurement and shape analyses. The results showed that CAFS was a cationic polymeric flocculant with high charge density, and its mesh starch chains grafted polyaluminium and polyferrous. At the intial stage, the main flocculation mechanism was adsorption and charge neutralization, while at the later stage, the high molecular weight and flexible linear chains of CAFS initiated bridge-aggregation and sweep-flocculation. And the pH value had significant influence on the flocculation characteristic. Under the optimal conditions, the removal rate of CODCr and colour reached 41.0% and 98.0% respectively, and the flocs were close-grained.
