摘要: 通过制备以海泡石为载体的负载二氧化钛的吸附剂,研究二氧化钛/海泡石对垃圾渗滤液的吸附作用。垃圾渗滤液经过初步处理后,在不同的浓度、pH、吸附剂投加量下测量吸附后的总有机碳,在不同的吸附时间点测量相应的总有机碳和化学需氧量。结果表明,垃圾渗滤液的吸附最佳效果的条件为:TiO₂/海泡石投加量为0.08 g,投加到稀释至COD为437.2 mg/L的垃圾渗滤液中,pH为3,TOC降解率为65.47%,COD降解率为55.56%。

Abstract: In this paper, adsorption of landfill leachate was studied by use of the carried TiO on sepiolite. After primary 2 treatment of the landfill leachate, total organic carbon was measured at different concentrations, pH and adsorbent dosage, and corresponding TOC and COD was tested at different adsorption time points. The results showed that the best conditions for adsorption of the landfill leachate were TiO₂/sepiolite dosage of 0.08 g, diluted landfill leachate with COD of 437.2 mg/L and pH value of 3, with TOC degradation rate of 65.47% and COD degradation rate of 55.56% achieved.
