| 摘 要： | 采用双循环两相生物工艺(BICT)处理生活污水,探讨了在不同运行模式和试验条件下系统的脱氮性能.试验结果表明:BICT工艺通过设置独立的生物膜法硝化池,强化了系统的硝化效率,减轻了泥龄对系统脱氮的影响,提高了脱氮的稳定性.运行模式和硝化液回流比是影响系统脱氮效果的主要因素.在适宜的条件下,系统的脱氮率可达85%以上,出水TN<15 mg/L. |

| Abstract: | The bi-cyclic two-phase(BICT)biological process was used to treat domestic sewage.The nitrogen removal performance of the system under different operation modes and test conditions was investigated.The test results indicate that through the adoption of a separate attached-growth reactor for nitrification,the nitrification efficiency is enhanced and the influence of SRT on nitrogen removal is diminished.Consequently,the stability of nitrogen removal is considerably improved.The operation mode and the reflux ... |
