摘　　要：针对北方农村家庭生活污水以灰水为主的状况,采用微型复合垂直流人工湿地处理模拟农村灰水。试验结果表明,稳定运行的微型复合垂直流湿地对灰水中COD的去除率为70%,对总氮的去除率为99%。通过从微型湿地不同高度处取样分析,研究了湿地内各形态氮间的降解规律。由于受到灰水中碳源不足和垂直流湿地供氧条件的限制,湿地内的硝化、反硝化作用不充分。通过增加曝气设备和补充天然碳源物质,可明显增强湿地内的硝化和反硝化作用。Aimed at the fact that the rural domestic sewage is mainly composed of grey water in northern China, a mini-integrated vertical-flow constructed wetland （IVCW） was used to treat simulated rural grey water. The results indicate that the removal rates of COD and TN are 70% and 99% respectively, The degradation characteristics of various types of nitrogen were investigated by analyzing the sampies from different depths. Also, because of limitations in carbon source shortage in the grey water and in oxygen supply, the effect of the nitrification and denitrification is insufficient. The effect of the two processes can be significantly improved through installation of aeration equipment and supply of a natural carbon source.
