摘要
活性污泥法－上向流间歇膨胀缺氧生物滤池（ＡＳ－ＵＳＥＡＦ）是一种新型的生物脱氮技术，其脱氮效果良好，系统脱氮率高达７０％～９０％，系统出水水质达到《生活杂用水水质标准》（ＧＪ２５．１－８９）。与传统正向过滤相比，可减少堵塞，且运行水头损失较小，采用间歇回流膨胀，可以促使气体逸出，保证配水均匀，促进生物膜更新或均化滤床生物量，使其具有良好的脱氮性能；与流化床相比可大大节省能耗。
In this thesis,the utility for Nvemoval technique of active sludgeupflow sequencing expanded anoxic biofilter(ASUSEAF),a new type Nremoval technique that the Nremoval rate is up to 70%～80%,is analysed.This technique can reduce clogging and the head loss in operation compared with traditional positive filtering process.The expansion with sequencing return flow can impel bubbles escaping,ensure welldistribution of water,promote biofilm of biomasss welldistributing within filter bed,so it has well function of denitrification.It can save more energy than fluid bed.
