摘　　要：比较了含电气石的新型陶粒生物膜载体和普通陶粒生物膜载体组成的电气石强化序批式生物膜反应器(SBBR)工艺和普通SBBR工艺的脱氮效能。结果表明,新型陶粒生物膜载体具有更好的吸附性能和生物亲和性。单周期分析表明,电气石强化SBBR工艺中氨氮浓度明显低于普通SBBR工艺,同步反硝化作用也强于普通SBBR工艺,表明电气石强化SBBR工艺的的脱氮效果优于普通SBBR工艺。90d的稳定运行进一步证明了电气石强化SBBR工艺的脱氮性能优于普通SBBR工艺,而且COD和总磷的去除效果也优于普通SBBR工艺。Tourmaline was applied to strengthen sequencing batch biofilm reactor （SBBR）. Nitrogen removal by tourmaline strengthening SBBR and common SBBR was compared. Results showed that tourmaline ceramic carrier had better adsorption capability and biological affinity. One cycle of the SBBR showed that ammonia nitrogen in tourmaline strengthening SBBR was lower than that in common SBBR. Denitrification in tourmaline strengthening SBBR was also stronger than that in common SBBR,demonstrating that nitrogen removal effect of tourmaline strengthening SBBR was better. 90 d stable running further confirmed the above conclusion. Moreover,tourmaline strengthening SBBR had better removal effects on COD and total phosphorus.
