| 摘 要： | 介绍了生物膜投料A／O(厌氧-好氧)接触氧化工艺脱氮试验研究。试验结果表明，本试验较活性污泥法大大节省停留时间，在好氧段停留时间为2．5h，缺氧段停留时间为1．5h的情况下，COD、NH3-N和TN的去处效率可分别达到约80％，90％和54％。在达到理想去除效果的同时大大节省了动力消耗和总运行费用。

| Abstract: | Tests on nitrogen removal by biofilm A/O process were introduced in this paper. The results showed that HRT was less greatly by this device than activat e d sludge process. And the removal efficiencies of COD, NH 3-N and TN can be obt ained 80 %, 90 % and 54 % respectively under some conditions. It saves the cost much and gets the satisfactory removal efficiencies. |
