摘　　要：为研发适用于我国农村分散性生活污水的处理装置,采用潮汐流人工湿地+景观湿地的组合式生态系统对农村散户生活污水进行处理,考察组合工艺对COD、TN、NH3-N和TP的去除情况。结果表明,组合工艺对COD、TN、NH3-N和TP的平均去除率分别为79.2%、82.95%、71.56%和69.00%,出水中COD和NH3-N、TN、TP的平均分别为29.30 mg/L和4.04、9.73、0.74 mg/L,低于GB 18918-2002的一级标准。该组合工艺对散户生活污水具有良好的适应性和处理效果,符合农村居民的生活特点,且运行能耗低、运作简便,适于推广运用。To develop a treatment device suitable for decentralized rural domestic sewage in China,the combined ecosystem of tidal flow constructed wetland and landscape wetland was used to treat decentralized rural domestic sewage.The removal rates of COD,TN,NH3-N and TP by combined process were studied.The results showed that,the removal rates of COD,TN,NH3-N and TP by combined process were 79.2%,82.95%,71.56%and69.00%respectively.The average mass concentrations of COD,NH3-N,TN and TP in the effluent were 29.30 mg/L,4.04 mg/L,9.73 mg/L and 0.74 mg/L,respectively,which were lower than the first level standard of GB 18918-2002.The combined process has good adaptability and treatment effect for the decentralized rural domestic sewage,and it conforms to the living characteristics of rural residents with low energy consumption and simple operation,which is suitable for popularization and application.
