| 摘 要： | 采用厌氧生物处理工艺，研究了在不同盐度下pH连续降低对硫酸盐还原和有机物去除率的影响。实验结果表明，硫酸盐还原菌有很强的适应pH变化的能力，在pH值达到4以下仍有60％的硫酸盐去除率。NaCl浓度由4g／L增加到50g／L抑制了各厌氧菌的活性，导致硫酸盐和有机物去除率的下降，但硫酸盐还原菌耐受性高于产甲烷菌等其他厌氧菌，在NaCl浓度为50g／L下，硫酸盐去除率能达到50％，而有机物去除率则低于30％。qRT—PCR表明了系统菌落中SRB随着环境的变化情况与化学指标结果相一致，该反应器体系中SRB在整个厌氧菌群落中只占了很小部分。

| Abstract: | In order to investigate the effects of salinity and pH on sulfate reduction and COD removal,an anaerobic technology was used.The result indicated that sulfate reduction efficiency could still reach 60% even when pH under 4,and the SRB had the strong adaptability to pH.The increase in influent NaCl concentration from 4 g/L to 50 g/L inhibited the activity of all anaerobe and resulted in the decrease of the sulfate reduction efficiency and COD removal.The sulfate and COD removal rates were 50% and less than 3... |
