摘　　要：某些工业废水中的贵金属离子具有很高的可回收价值,而微生物法还原贵金属离子为单质形态的研究成果使其成为可能。本文综述了微生物法水处理技术还原贵金属离子为单质形态的机理、影响因素、微生物种类和贵金属离子种类。另外,本文还分析了微生物法还原贵金属离子为单质形态的发展前景和存在的问题。Microbial method has unique advantages in the treatment of wastewater containing metal ions, among which is reducing precious metal ions to their elemental form by making use of the reducibility of microorganisms. This paper reviews the mechanism of microbial reduction of metal ions and the influential factors toward the reaction of microorganisms, identifies the category of microorganisms that can reduce metal ions, metal ions can be reduced by a bioelectroehemical system and the applications of microbial reduction process under the effect brought by microorganisms. In addition, this paper also incorporates the prospect of development and potential defects in applying microbial reduction to recover metal ions in industrial wastewater.
