The Treatment of Landfill Leach by Solar/H2O2/Ferric Oxalate

  • 摘要: 以Fe3++草酸盐络合物/H2O2作光氧化剂,利用太阳光对垃圾渗滤液进行了光氧化降解实验.结果表明:在溶液的初始pH为3.0,H2O2投加量为460 mg/L,ρ(Fe3++)为20 mg/L条件下,反应60 min后,CODCr去除率可达80%左右;溶液的pH,ρ(H2O2)和ρ(Fe3++)对光解过程有显著影响,而且在太阳光的照射下,CODCr去除率比在紫外光下高.在一定实验条件下,用日光/H2O2/草酸铁体系对城市垃圾渗滤液处理效果较好,可作为垃圾渗滤液的深度处理.
