摘　　要：采用土壤柱试验研究了土壤渗滤对再生水中有机微污染物的去除性能。结果表明,土壤柱对再生水中的DOC、UV254、总氮和总磷有较好的去除效果,并具有较高的抗冲击负荷的能力;土壤表层10 cm厚度对DOC的去除起主要作用;UV254和AOX在土壤表层10 cm厚度降解效果不明显,随着深度增加去除率逐渐升高;液相色谱-有机碳探测(LC-OCD)检测结果表明,土壤柱对溶解性有机物质的去除主要体现在对多糖物质的降解上,其次是有机酸类,对腐殖质也有一定的去除作用。Soil column experiment was conducted to study performance of organic micro-pollutants removal from recycled wastewater by soil infiltration. Results showed that DOC, UV254,TN and TP were removed effectively with good stability. DOC was removed mostly in the top 10 cm of soil, while UV254 and AOX were removed along the whole soil column. The liquid chromatography-organic carbon detection （LC-OCD） ehromatograms showed that DOC reduction is mainly due to degradation of polysaccharides, organic acids and humic substances.
