| 摘 要： | 采用反应期缺氧/好氧SBR工艺去除亚铵法造纸废水中氮的研究结果表明:该工艺脱氮的最佳操作条件为:缺氧、好氧时间比1:1.5,运行周期为8h;SRT≥12d,NH3-N负荷率＜0.063g/(g·d);当进水中CODcr浓度为1200～1800mg/L,NH3-N浓度为135～200mg/L,NOx-N浓度为7～10mg/L时,没有外加碳源时,氨氮的去除率为95%,总氮的去除率为66%,投加乙酸钠后,总氮的去除率提高到85%;投加乙酸钠的量为125mg/L(以CODCr计)最经济、有效.

| Abstract: | The experiment results showed that the best technology of removing the nitrogen was anoxic time to aerobic time of 1:1.5, a cycle of 8 hours; the SRT should be more than 12 d and the loading of NH3-N should be less than 0.063 g/(g.d); when the concentration of CODCr, NH3-N and NOx-N was 1200-1800 mg/L, 135-200 mg/L and 7-10 mg/L respectively, without external carbon sources, the removal rate of NH3-N and TN could respectively achieve 95% and 66%; after adding sodium acetate the removal rate of TN could get to 85%. The addition of sodium acetate at the concentration equivalent to theoretical CODCr values of 125 mg/L appeared to be the most economical and reliable option. |
