摘要

摘要: 采用共沉淀法制备Fe₃O₄-RGO纳米复合催化剂,并将其应用于类芬顿处理垃圾渗滤液,研究了反应时间、初始pH值、催化剂质量浓度和H₂O₂投加量对Fe₃O₄-RGO纳米复合催化剂类芬顿降解垃圾渗滤液COD去除率的影响。结果表明:反应时间为90 min,初始pH值为3,催化剂质量浓度为1 mg/L,H₂O₂投加量为0.08 mmol/L时,COD去除率达到最大值64.7%。有机物组分对比结果显示,类芬顿反应后垃圾渗滤液中大分子有机物得到较好的降解转化。Fe₃O₄-RGO纳米复合催化剂具有较好的重复利用性,重复使用5次后对垃圾渗滤液的COD去除率仅降低2.3%。

Abstract: Fe₃O₄-RGO nanocomposite catalyst was prepared by coprecipitation method and then investigated in Fenton-like process when treating landfill leachate. The effect of reaction time, initial pH value, catalyst mass concentration and H₂O₂ dosage on COD removal rate of landfill leachate were studied. The results indicated that when the initial pH value was 3, catalyst mass concentration was 1 mg/L and H₂O₂ dosage was 0.08 mmol/L, the removal rate of COD removal rate reached a maximum of 64.7% after 90 minutes reaction. The comparison of organic components showed that the macromolecular organic matter in the landfill leachate was well degraded after Fenton-like treatment. The Fe₃O₄-RGO nanocomposite catalyst had good repeatability, and the COD removal rate of landfill leachate was only reduced by 2.3% after 5 times usage.
