摘　　要：以椰糠作为湿地工作层主要填料,采用复合垂直流人工湿地处理海南天然橡胶加工业低浓度废水。结果表明,在144 mm/d水力负荷条件下,椰糠填料人工湿地对废水中的COD、BOD5、NH3-H及TP的去除率分别达到68.99%、66.49%、59.55%和75.22%,显著高于无椰糠对照组。当水力负荷提高至216 mm/d,系统运行稳定,出水水质仍能达到污水排放标准(GB 8978-1996)和《农业灌溉水质标准》(GB5084-92)。The integrated vertical flow constructed wetland with coconut husk for the rubber industrial tail water treatment was investigated. Results showed that the average removal efficiencies of COD, BOD5 , NH3-N and TP were 68.99% ,66.49% ,59.55% and 59.55%, respectively. The effect of filter media on purification efficiency of integrat- ed vertical flow constructed wetlands was significant. At the hydraulic loading rate of 216 mm/d, the effluent water quality meets the First Grade Standard of Integrated Wastewater Discharge （GB 8978-1996）and Agricultural Irrigation Water Quality （ GB 5084-92）.
