摘要
微量的金属离子对微生物的生长有益,但当它们达到一定的质量浓度时均会对微生物的生长速率和COD的去除速率产生抑制作用。本文综述了金属离子对微生物影响,特别是对于活性污泥微生物影响的研究现状,包括金属离子对微生物的影响机理。各浓度金属离子对污水生物处理过程的具体影响。进而为利用低浓度金属离子促进活性污泥法处理效能的研究提供依据。
Though metal ions in trace concentration are beneficial to the growth of microorganisms, they inhibition effect on the kinetics at high concentration. They inhibited the microorganism bring about rate and the chemical oxygen demand （COD）removal rate. This paper reviewed the effect of metal ions on microorganisms, especially, the effect on activated sludge microorganisms. The text includes the effect of metal ions on microorganisms and its mechanism; and when put into different concentrations of metal ions, what results will be. Then we can provide a research basis for how to take advantage of metal ions to accelerate the effect of activated sludge.
