摘　　要：以煤矸石为研究对象,通过实验考察了2种具有协同抑制作用的氧化抑制剂对煤矸石山中Fe^(2+)氧化率的抑制效果;通过扫描电镜(SEM)观察菌体形态,对抑制机理进行了初步探讨。结果表明,2种氧化抑制剂联合使用,对煤矸石中Fe^(2+)的氧化具有明显的协同抑制效果,将质量浓度3 mg/L的苯扎氯铵、体积分数为0.08%的戊二醛以体积比1∶1混合后施加于煤矸石中,Fe^(2+)氧化率可低于14%。Taking coal gangue as the research object,this paper investigated the inhibitory effect of two synergistic oxidation inhibitors on the oxidation of Fe^(2+)in coal gangue hill through experiments.Scanning electron microscope(SEM)was used to observe the morphology of the cell and the inhibition mechanism was preliminarily discussed.The results show that when the two oxidation inhibitors are used together,they have an obvious synergistic inhibitory effect on the oxidation of Fe^(2+)in coal gangue.When benzalammonium chloride with the mass concentration of 3 mg/L and glutaraldehyde with the volume fraction of 0.08%are mixed in coal gangue in a volume ratio of 1∶1,the oxidation rate of Fe2+can be lower than 14%.
