| 摘 要： | 糖蜜酒精废水属于富含硫酸盐的高浓度有机废水,采用微氧厌氧生物脱硫技术进行处理。在同一反应器中先利用硫酸盐还原菌(SRB)将糖蜜酒精废水中的硫酸盐还原为硫化物,然后利用无色硫细菌(CSB)在微氧状态下将硫酸盐还原产物———硫化物氧化成硫单质,消除了硫化物对产甲烷菌的毒害作用。研究结果表明,此工艺脱硫效果显著。

| Abstract: | The molasses distillery wastewater,one of the typical high-concentration organic watewater with high sulfate,was treated using oxygen-limited anaerobic biological desulphurization process.The sulfate in molasses distillery wastewater was firstly reduced into sulfide by sulfate reducing bacterium(SRB).Then,the sulfide formed in the former stage was oxidized biologically into sulfur with colorless sulfur bacterium(CSB) under oxygen-limited condition,in which the sulfide poisonous influence on methanogenesis could be eliminated.The experimental results showed that this process had a remarkable desulphurization effect. |
