| 摘 要： | 以正交设计方法为基础，以COD去除率为指标，确定了聚硅铝铁硼（PSAFB）最优制备条件，研究了Fenton-PSAFB混凝法处理城市生活垃圾压滤液的最优反应条件和处理效果。结果表明：以200 mL生活垃圾压滤液为处理对象，复合絮凝剂PSAFB的最优制备工艺条件为：Al/Si为1/2，Fe/Si为1/2，B/Si为1/6；其最优反应条件为：pH值为5.0，投加量为200 mg/L（以SiO2计)；Fenton法最优反应条件为：pH值为3.0，30%H2O2为20 mL，1 mol/L FeSO4为30 mL；采用最优反应条件的Fenton-PSAFB处理垃圾压滤液，浊度去除率达到95.2%，COD去除率达到84.2%，BOD5去除率达到81.5%。

| Abstract: | By applying orthogonal design, Fenton oxidation and poly (silicon/aluminum/ferric/boron) complex(PSAFB) flocculant were used to treat leachate produced during compressing municipal domestic refuse, and the treatment effects and conditions were investigated. Preliminary results show the optimum synthesis condition, that is the molar ratio of aluminum to silicon being 1/2, the molar ratio of ferric to silicon being 1/2 and the molar ratio of boron to silicon being 1/6. The experiment with Fenton shows that the effects of three factors on the removal efficiency of COD are in the following decreasing order: dosage of H2O2, pH value and dosage of FeSO4.Under the optimum conditions, the removal rates of turbidity, COD and BOD5 reach 95.2%, 84.2% and 81.5% respectively. |
