摘　　要：传统生物脱氮工艺耗能多 ,反硝化时还消耗碳源。半硝化 -厌氧氨氧化 ( SHARON-ANAMMOX)是一种全新的脱氮工艺。其原理是首先由亚硝化细菌将废水中 1 /2氨氮氧化为NO-2 ,剩余的氨氮与所生成的 NO-2 以等摩尔比例 ANAMMOX菌作用生成 N2 。因耗能少且不消耗碳源 ,故具有可持续发展意义。Conventional nitrogen elimination process consumes more energy and needs carbon source during denitrification. SHARON-ANAMMOX process is a totally new technology. The principle is that half ammonium in wastewater is oxidized to NO - 2 by nitrisomonas at first, then the remainder ammonium and produced NO - 2 with molar ration 1∶1 result in N 2 by Anammox bacteria. The process consumes less energy and needs not carbon source. So it has sustainable development signification.
