摘　　要：研究了中试规模的潜流人工湿地废水处理系统中有机物的去除,探讨了总悬浮物(total suspended solid,TSS)、总有机碳(total organic carbon,TOC)、总碳(total carbon,TC)等对有机物(COD)去除的影响.结果表明,进水COD,TSS,BOD,TOC和TC浓度对潜流湿地系统中COD的去除有显著影响,通过沿程样品的分析发现,COD的去除主要发生在湿地的前半部.The removal of organic matters （COD） in a pilot-scale subsurface flow constructed wetland system was studied in the present study. Factors such as influent COD concentration, suspended solids, BOD, total organic carbon, total carbon affecting COD removal were invstigated. The results indicated that the concentrations of influent COD, SS, BOD, TOC and TC had significant effect on COD removal. A survey of COD profiles along the wetland length revealed that COD removal was mainly occurred in the area located in the middle of the constructed wetland.
