摘　　要：采用SBR工艺处理氨氮废水,试验结果验证了好氧反硝化的存在,在好氧脱氮总量中按照氨氮→硝态氮(包括硝基氮和亚硝基氮,以NOX--N表示)→含氮气态物这一传统生物脱氮途径进行的仅占46.5%,在扣除生化合成反应所需氮素以及游离氨解析吹脱之外,尚有半数左右的氮在硝化过程中尚未形成NOX--N之前便已转化为不明物质而丢失。In this study,high strength ammonia nitrogen wastewater is treated by SBR.The results confirm the pre-sence of aerobic denitrification and show that46.5%nitrogen is removed following the sequence of NH 4+ -N→NO X- -N→gaseous nitrogen compounds in aerobic denitrification route.Besides the nitrogen consumed in biochemical composition and except the nitrogen blown off,about half of N has been lost as some unknown substances before conversed to NO X- -N.
