Therefore, how to reduce the effect of organic matter on the activity of Anammox is a difficult point in its application.In this paper, effect of organic matter (type and concentration) on the process of anaerobic ammonium oxidation is introduced, and research progress in effected factors of anaerobic ammonium oxidizing is summarized. It suggestes that under the organic matter concentration between 100 and 200mg/L, anammox bacteria activity is not inhibited. It can also regulate the ectopic utilization of different types and concentrations of organic compounds to achieve the purpose,which removing carbon and nitrogen currently with the synchronization of the anaerobic ammonium oxida-tion, methaogenesis or denitrification．It concludes that the further metabolic mechanism of anammox bacteria, and the competition and cooperation mechanism could go on in the influence of organic matter on Anammox, as well as the research of bacteria enrichment purification.. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
