| 摘 要： | 研究静态条件下硫酸盐还原菌处理硫酸盐废水时,COD/SO4^2-比值对硫酸盐废水处理效果的影响.模拟硫酸盐废水用无水硫酸钠配制,以乳酸钠为电子供体（COD）.实验结果表明,当T=35℃,初始pH=6.8时,COD/SO4^2-≥3时SO4^2-的去除率可达到90%以上,同时COD的去除率达到约55%,处理后体系的pH值有所上升.选择恰当的COD/SO4^2-比值对实际工程的工艺运行具有重要意义.

| Abstract: | The effect of COD/SO4^2-ratio on sulfate removal was studied on the static condition when anhydrous sodium sulfate was simulated wastewater and sodium lactate was electron donor,using sulfate-reducing bacteria（SRB）.The results show that when the ratio of C/S≥3,sulfate removal rate can be achieved over 90% on the condition of T=35℃,initial pH=6.8.And the treated water′s pH increase,as well as the COD removal rate is about 55%.The conclusion is that the COD/SO4^2- is critical in the wastewater treatment. |
