摘　　要：针对农村污水较为分散的特点以及目前农村污水处理技术方法仍存在不足的实际状况,研究设计了一种新型农村污水生态净化回用工艺.结果表明:该工艺将厌氧生化和人工湿地技术有机结合,可以大幅提高生物降解效率,有效降低农村污水中COD、TN、NH3-N和SS的含量,使出水水质显著改善,可作为中水回用,同时大幅度减少了人工湿地的占地面积;通过对太阳能的采集和储蓄,可以保证该工艺在环境温度较低时仍能正常高效工作.According to the characteristics of the rural sewage,such as scattered distribution and backwardness of wastewater treatment,a new reused water progress for rural sewage was designed.The results showed that using the new sewage treatment process and technique could improve the efficiency of biological degradation and the quality of the reclaimed water,since it combines anaerobic biochemistry with constructed wetland technology.The treated sewage water might be used as reclaimed water and the area of the constructed wetland reduced substantially as well.By utilizing the solar energy,the sewage treatment could working properly and efficiently even in the low-temperature environment.
