摘要
以草酸铁络合物/H2O2作光氧化剂,利用日光对垃圾渗滤生化出水进行了光氧化降解试验。结果表明,在溶液的初始体系pH=3.0,H2O2投加量为460mg/L,Fe3+质量浓度为20mg/L条件下,反应60min后,CODCr去除率可达80%以上;溶液初始体系的pH、H2O2和Fe3+的投加量及废水的水质对光解过程有显著影响,而且在太阳光照射下,CODCr去除率比紫外光照射下高。研究表明,在一定试验条件下,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。
Ferric oxalate complexes and H2O2 as photooxidative was used to degrade the landfill leachate under solar irradiation. The results indicate that under the initial conditions of pH 3.0, H2O2 460 mg/L and Fe 3+20 mg/L, the removal of COD Cr can reach over 80% in 60 minutes. It is found that the initial pH of the solution and the concentrations of H2O2 and Fe 3+ and the quality of wastewater have significant effect in this photooxidative process. The removal of COD Cr is higher under solar irradiation than under UV irradiation, and the research shows that under the selected conditions, using solar/H2O2/ferric oxalate complexes to treat the landfill leachate has better efficiency, and it can be used as advanced treatment.
