| 中文摘要: |
| 针对人工湿地内部溶解氧浓度不足的问题，利用页岩空心砖构建自动增氧型湿地系统，研究构建系统对氮的净化效率。结果表明，构建自动增氧型湿地系统各基质层污水溶解氧（DO）浓度均在 0.5 mg/L以上，泥土、粉煤灰和砾石三层基质对总氮（TN）的去除率分别达到了38.9%、33.2%和22.9%，构建的自动增氧型湿地系统净化效果略好于人工强化供氧湿地系统。故可利用页岩空心砖构建自动增氧型湿地系统，以增强其系统内部供氧能力，提高湿地系统的除氮能力。 |
| 英文摘要: |
| A self-aeration constructed wetland system was built with shale hollow bricks to solve the problem of dissolved oxygen deficiency in constructed wetlands, and the nitrogen removal efficiency of the system was studied. The experimental result showed that the DO concentration of waste water in each matrix layer in self-aeration constructed wetland system was all above 0.5 mg/L. The total nitrogen removal rates of clay layer, fly ash layer and gravel layer were 38.9%, 33.2% and 22.9%, respectively. The purification efficiency of constructed self-aeration wetland system was higher than that of artificial enhanced oxygen wetland system. As a conclusion, shale hollow bricks can be used to build self-aeration constructed wetland system to increase the internal oxygen supply and improve the nitrogen removal efficiency of the wetland system.
