  • 摘要: 本文以混凝预处理后的上海老港垃圾填埋场渗滤液纳滤浓缩液为研究对象，采用混凝预处理、Fenton氧化法和生化法相结合的工艺对其进行处理，将其出水COD从2930 mg·L-1降至100 mg·L-1以下.采用响应曲面法研究了Fenton氧化法处理经过混凝预处理纳滤浓缩液过程中，各个影响因素之间的相互作用关系，并确定了最佳实验条件，即FeSO4·7H2O投加量为62.5 mmol·L-1、H2O2投加量为121.8 mmol·L-1、初始pH 3.0.在此条件下，Fenton氧化法可使混凝预处理出水的COD降低39.0%.进一步研究表明，Fenton氧化后纳滤浓缩液中芳香环类污染物减少、腐殖化程度降低.经过3 h的Fenton氧化法处理后，BOD5/COD从纳滤浓缩液原液的0.02上升到0.29.将垃圾渗滤液纳滤浓缩液Fenton氧化法处理后出水与垃圾填埋场渗滤液的纳滤出水1∶1混合，进行序批式活性反应器（SBR）处理，在水力停留时间为2 d时，出水COD可降低至96.0 mg·L-1.
    Abstract: In this study, coagulation, Fenton process combined with SBR were used to treat concentrated landfill leachate from Shanghai Laogang landfill site. For the Fenton process, response surface methodology was employed to optimize the three factors, namely FeSO4·7H2O dosage, H2O2 dosage and initial pH. It was found that 39.0% COD was removed under the optimum conditions of 62.5 mmol·L-1 FeSO4·7H2O, 121.8 mmol·L-1 H2O2 and initial pH 3.0. After Fenton treatment, aromatic hydrocarbons and degree of humification in the concentrated leachate decreased. And BOD5/COD increased from 0.02 to 0.29 after 3 hours' Fenton treatment. In SBR process, COD of the concentrated leachate from nanofiltration (1∶1 mixed with nanofiltration effluent) decreased to 96.0 mg·L-1 under the condition of HRT 2 d.
