摘要: 本文探测了18种金属离子对苯酚降解菌XH-10生长和苯酚降解的影响。结果显示:Al3+、Co2+、Cu2+、Hg2+、Ni2+、Ag+对苯酚降解菌XH-10的生长和苯酚降解有强烈的抑制作用;K+、Zn2+、Cr2+、Mo2+、Pb2+、Sn2+对苯酚降解菌XH-10的生长和苯酚降解有一定的抑制作用,但在低浓度时,XH-10有一定的生长和苯酚降解潜力;Ca2+、Mg2+、Na+、Mn2+在较低浓度时对苯酚降解菌XH-10的生长有促进作用,对苯酚降解的抑制作用较小,在高浓度时对菌体生长和苯酚降解的抑制作用明显;Ba2+对苯酚降解的抑制作用明显,而在较低浓度时对苯酚降解菌XH-10的生长有促进作用;Fe3+对菌体生长的抑制作用明显,而在较低浓度时对苯酚降解菌XH-10的苯酚降解抑制作用较小。其研究结果对菌株XH-10用于含酚废水的处理提供了一定的依据。

Abstract: This article surveyed the influence which 18 metal ions on phenol degrading bacterium XH-10 growth and the phenol degradation. The results showed: Al3+, Co2+, Cu2+, Hg2+, Ni2+, Ag+ have intense inhibitory action to the phenol degrading bacterium XH-10 growth and the phenol degeneration; K+, Zn2+, Cr2+, Mo2+, Pb2+, Sn2+ have certain in-hibitory action to the phenol degrading bacterium XH-10 growth and the phenol degeneration, but at low concentrations, XH-10 has certain growth and the phenol degeneration potential; Ca2+, Mg2+, Na+, Mn2+ at lower concentration to the phenol degrading bacterium XH-10 growth have promoter action, degrades the inhibitory action to be small, at high concentrations to the bacterium growth and the phenol degradation have obvious inhibitory; Ba2+ the inhibitory action which degrades to the phenol is obvious, but at lower concentration have promoter action to the phenol degrading bac-terium XH-10 growth; Fe3+ the inhibitory action which growth to the bacterium is obvious, but at lower concentration have smaller inhibitory action to the phenol degrading bacterium XH-10 phenol degeneration. The results of the phenol degrading bacterium XH-10 for the treatment of wastewater containing phenol provides certain basis.
