| 中文摘要: |
| 设计并构建了天然沸石与泥炭生物滤池装置，实验考察其在微污染景观水中脱氮除磷性能，研究其形成生物膜系统后对污染物去除的机理及效果。结果表明：该装置具备良好的生物去除污染物效果，运行稳定后CODcr、NH4+-N和TP去除率分别可达80%、95%和41%；通过生物作用可使天然沸石与泥炭再生，实现材料持续使用。 |
| 英文摘要: |
| A biofilm system device with natural zeolite and peat was designed to observe the nitrogen and phosphorus removal efficiency in micro-polluted landscape water by experiments. The mechanism and pollutants removal effects were also investigated after the formation of the biological membrane. Results verified the effective pollutants removal capacities of the whole system. About 80% of CODcr, 95% of NH4+-N and 41% of TP can be removed after the operation stabilized. Moreover, the natural zeolite and peat can be regenerated by the biological behavior to prolong the lifecycle of the materials. |
