| 摘 要： | 针对人工湿地中溶解氧浓度不足和脱氮率偏低的问题,设计了自动增氧人工湿地进行农村生活污水处理对比试验研究.结果表明,自动增氧湿地内的DO浓度比普通人工湿地高0.3me期mg/L左右,TN、NH<,4><'+>-N去除率分别达到了67.41%、69.114%,比普通湿地高14.57%、19.79%.同时,自动增氧人工湿地系统中的亚硝化细菌、硝化细菌数量均高于普通人工湿地系统,说明自动增氧措施对于提高人工湿地脱氮效率是有效的. |

| Abstract: | A laboratory-scale experiment was conducted on a simulation setup of vertical flow constructed wetland with enhanced self-aeration intended to improve nitrogen removal of domestic wastewater treatment in rural area,involving a comparative study of the self-aeration constructed wetland with the conventional one.It was found from the experiment that DO concentration and the amount of nitrite bacteria and denitrification bacteria in the self-aeration system were higher than the conventional system,thus leading... |
