| 摘 要： | 运行周期中反硝化运行和硝化运行的时间比ｔＤＮ／ｔＮ是平衡处理系统反硝化，硝化能力的重要参数，实验室条件下分别比较了ｔＤＮ／ｔＮ为０．２７，０．４０，０．４７，０．７５和１．０的５种不同组合的运行效果。结果表明，当ｔＤＮ／ｔＮ为０．４０时，即硝化能力略大于反硝化潜能时，脱氮效果最好。

| Abstract: | In Triple Oxidation Ditch system,the time ratio of denitrification phase and nitrification phase, t DN / t N,is an important parameter to balance denitrification potential and nitrification capability.By comparing five different t DN / t N,0 27,0 40,0 47,0 75,1 0 in lab equipment(the cycle time was equal to 8h),the best nitrogen removal efficiency can be achieved while t DN / t N being 0 40.Changing operating cycle from the current 8h to 12h,the T ditch system gets a better treatment efficiency in nitrogen removal,and the volume availably to denitrification and nitrification in the system increases. |
