中文摘要

混凝工艺是一种广泛应用于水和废水处理的技术。本论文以Na₂SiO₃·9H₂O、Fe₂(SO₄)₃和MgSO₄为原料，合成了新型复合聚硅酸镁–硫酸铁混凝剂。系统地研究了老化时间、Fe:Si:Mg和OH:M摩尔比（M表示金属离子）对所制备的PFMS的混凝性能的影响，以获得最佳的混凝剂。结果表明，PFMS混凝剂对处理模拟腐殖酸-高岭土地表水和活性染料废水具有良好的混凝性能。当摩尔比控制在Fe:Si:Mg=2:2:1和OH:M=0.32时，所获得的PFMS表现出优异的稳定性和高的凝固效率。紫外线(UV)₂₅₄的去除率为99.81%，在30 mg·L^–1的剂量下，地表水的残余浊度达到0.56 NTU。混凝剂在实验室静置120 d后，对地表水UV₂₅₄和残余浊度的去除率分别为88.12%和0.68 NTU，符合地表水处理要求。此外，结合镁盐和铁盐的优点，大大提高了活性染料废水的混凝性能。与聚硅酸硫酸铁（PFS）和聚硅酸硫酸镁（PMS）相比，PFMS混凝剂在7–13的pH范围内具有更好的脱色作用。

Abstract

Abstract

The coagulation process is a widely applied technology in water and wastewater treatment. Novel composite polyferric magnesium–silicate–sulfate (PFMS) coagulants were synthesized using Na₂SiO₃·9H₂O, Fe₂(SO₄)₃, and MgSO₄ as raw materials in this paper. The effects of aging time, Fe:Si:Mg, and OH:M molar ratios (M represents the metal ions) on the coagulation performance of the as-prepared PFMS were systematically investigated to obtain optimum coagulants. The results showed that PFMS coagulant exhibited good coagulation properties in the treatment of simulated humic acid–kaolin surface water and reactive dye wastewater. When the molar ratio was controlled at Fe:Si:Mg = 2:2:1 and OH:M = 0.32, the obtained PFMS presented excellent stability and a high coagulation efficiency. The removal efficiency of ultraviolet UV₂₅₄ was 99.81%, and the residual turbidity of the surface water reached 0.56 NTU at a dosage of 30 mg·L^–1. After standing the coagulant for 120 d in the laboratory, the removal efficiency of UV₂₅₄ and residual turbidity of the surface water were 88.12% and 0.68 NTU, respectively, which accord with the surface water treatment requirements. In addition, the coagulation performance in the treatment of reactive dye wastewater was greatly improved by combining the advantages of magnesium and iron salts. Compared with polyferric silicate–sulfate (PFS) and polymagnesium silicate–sulfate (PMS), the PFMS coagulant played a better decolorization role within the pH range of 7–13.
