摘　　要：厌氧氨氧化为高效低耗生物脱氮技术,但金属元素对该工艺的作用存在两面性,一方面其促进作用可提高工艺处理效果,另一方面抑制作用使其工程应用受到一定限制.为此本文从生物化学和污水处理工艺的角度,系统地总结了国内外金属对厌氧氨氧化影响的研究现状,重点分析与讨论了不同金属元素对厌氧氨氧化细胞结构和相关酶蛋白活性等的影响和作用机理;综述了金属元素对厌氧氨氧化工艺运行的影响,讨论与分析了不同厌氧氨氧化工艺的半抑制浓度及活性修复方法.As an efficient and low energy consumption biological denitrification technology, anaerobic ammonium oxidation （ANAMMOX） has many advantages and bright development prospects. However, many metallic elements have two-sided effectd on ANAMMOX. One is enhancement effect which improves treatment efficiency, but the other is inhibition that limits its applications. Thus, from the biochemical reaction view point, this article summarizes the research status, emphatically analyzes the effects and mechanisms of metallic elements on ANAMMOX. From technology view point, the article also compares the different effects of metallic elements on ANAMMOX process operation, mainly discusses the 50% inhibiting concentration （ICs0） and recovery methods for heavy metal inhibition.
