| 摘 要： | 在序批式移动床生物膜反应器(SBMBBR)内,对进水COD较低的条件下,模拟生活污水的亚硝化及脱氮性能进行了研究.结果表明,缺氧时间、进水COD、NH44 -N浓度、pH值以及溶解氧对亚硝化过程有明显影响.在进水COD为100mg·L-1NH4 4-N浓度为50mg·L-1时,调控溶解氧、pH,出水的亚硝化率可到99.7%,总氮去除率可达66.4%,表明系统中发生了同步短程硝化反硝化.

| Abstract: | Nitrosification and denitrification in an artificial domestic wastewater with low COD were studied in a sequencing batch moving bed biofilm reactor (SBMBBR). The results showed that the shortcut nitrification was influenced by anoxic time, COD, NH+4-N, pH and dissolved oxygen. When COD in the wastewater feed was 100 mg·L-1 and NH+4-N was 50 mg·L-1, a 99.7% nitrite accumulation ratio and 66.4% TN removal were reached by adjusting the DO and pH in the process, which meant that simultaneous shortcut nitrification and denitrification occurred in the system. |
