垃圾渗滤液由于色度高、可生化性差,有时候需采用高级氧化技术（如Fenton法）处理。利用硅藻土酸洗改性产生的酸洗废水与30%H2O2制成Fenton试剂处理初始色度为800倍,COD浓度为810.4 mg/L的垃圾渗滤液。结果表明,当酸洗液与30%H2O2的体积比为6∶4,pH值为3.0,有紫外光照和搅拌的条件下,色度和COD的去除效率最好,分别达到了96.25%和74.14%;且产生的污泥量（干重）最少。

Due to high chroma and poor biodegradability,advanced oxidation technology,such as fenton,is employed to deal with landfill leachate.In this study,acid pickle obtained from the process of diatomite modification was combined with 30% H2O2 to generate Fenton reagents to deal with the landfill leachate with initial chroma 800 and COD concentration of 810.4 mg/L.The results showed that when the best ratio of acid pikle and 30%H2O2 was 6∶ 4（V/V）,the react time was 1 h,and the value of pH was 3.0,the removal rates of the chroma and COD reachd 96.2...
