【摘要】 本试验主要考察间歇反应器缺氧阶段硝酸盐氮负荷ＮＮＯ－ｘ－Ｎ（ＫｇＮＯ－ｘ－Ｎ／ＫｇＭＬＳＳｄ）对脱氮效率的影响。试验结果表明：在一定水温和ＢＯＤ５／ＮＯｘ－Ｎ下，ＮＮＯｘ－Ｎ负荷对脱氮效率有显著影响。在反应器中采用高浓度污泥是降低ＮＮＯｘ－Ｎ的有效途径，有利于反应器脱氮速率ＶＤＮ（ｍｇ／ｌ·ｍｉｎ）的提高。此外，通过正交试验得出了在ＢＯＤ５／ＮＯ－ｘ一定时，ＮＮＯ－ｘ－Ｎ、Ｔ℃与脱氮效率ηＮＯ－ｘ－Ｎ之间的数量关系式更多还原

【Abstract】 The influence of nitrate nitrogen loading on denitrification was studied during anoxic process in intermittent aeration system The test results show that the influence is remarkable The nitrate nitrogen loading N NO - x-N (KgNO - x-N/KgMLSS·d) is down as high MLSS is adopted in the reactor In addition,The quantitative relation among the N NO - x-N ,T℃ and η NO - x-N % is obtained by the regression analysis更多还原
