摘　　要：以台湾省台东县关山人工湿地系统为研究对象,探讨了曝气氧化塘+人工湿地组合工艺处理农村污水的效果。2008年8月—2018年12月,每月采集1次数据,共收集125组数据。结果表明,人工湿地系统对BOD_(5)的平均去除率为(61.55±16.71)%,平均表面污染物负荷为(1.23±0.52)g/(m^(2)·d);对SS的平均去除率为(63.39±11.18)%,平均表面污染物负荷为(2.62±2.36)g/(m^(2)·d);对NH_(4)^(+)-N的平均去除率为(82.21±12.11)%,平均表面污染物负荷为(1.98±0.34)g/(m^(2)·d);对TN的平均去除率为(67.88±13.89)%,平均表面污染物负荷为(1.78±1.01)g/(m^(2)·d);对TP的平均去除率为(71.31±12.31)%,平均表面污染物负荷为(0.13±0.05)g/(m^(2)·d)。该工艺运行稳定,处理效果好,出水水质满足台湾省相关水质标准要求。整个系统结合生态景观,构建亲水环境,表现出良好的环境效益。The effect of a combined process of aeration pond and constructed wetland on the treatment of rural sewage was explored in Guanshan Constructed Wetland,Taidong County,Taiwan Province.From August 2008 to December 2018,a total of 125 groups of data were collected through the data collection for once a month.The removal efficiencies of BOD_(5),SS,NH_(4)^(+)-N,TN and TP by the constructed wetland system were(61.55±16.71)%,(63.39±11.18)%,(82.21±12.11)%,(67.88±13.89)%and(71.31±12.31)%,respectively,and the average surface pollutant loading rates of BOD_(5),SS,NH_(4)^(+)-N,TN and TP were(1.23±0.52)g/(m^(2)·d),(2.62±2.36)g/(m^(2)·d),(1.98±0.34)g/(m^(2)·d),(1.78±1.01)g/(m^(2)·d)and(0.13±0.05)g/(m^(2)·d),respectively.The process operated stably with a good treatment performance,and the effluent quality met the requirements of relevant water quality standards of Taiwan Province.The whole system was combined with the ecological landscape to build a hydrophilic environment,and showed good environmental benefits.
