| 摘 要： | 20世纪90年代初在污泥处理系统中发现了氮素形态转化的新途径--厌气铵氧化过程.厌气铵氧化过程是铵以亚硝酸根为电子受体在自养细菌参数下氧化成氮气的过程.但目前尚无土壤、河、湖、海底泥等自然系统中是否存在厌气铵氧化过程的报道.由于该过程无需外加有机碳,耗氧和处理产生污泥少,用于污泥脱氮成本较低,具有很大潜力.

| Abstract: | The innovative process of nitrogen conversion-anaerobic ammonium oxidation(Ana m mox)-is introduced in the paper.Anammox is a biologically mediated process i n which ammonium is oxidized with nitrite serving as electron acceptor under anaer obic condition.Since the process applied to remove ammonium from wastewater does not need additional COD,consumes less O2,and produces less secondary sludage, there is a great potential for applying this process to wastewater treatment.It is also worth to explore the existence of anammox process in natural systems suc h as paddy soil,sediments of rivers,lakes and marines. |
