| 摘 要： | 利用厌氧颗粒污泥对烟气中SO2吸收生成的硫酸盐或亚硫酸盐废水进行处理，考察起始SO4^2-质量浓度、初始COD／SO4^2-、初始pH、接种污泥质量、亚铁离子等限制性生态因子对硫酸盐还原的影响。结果表明：在起始SO4^2-质量浓度800mg／L，初始COD／SO4^2-为3．0，pH值为7．0，接种污泥质量为31．10gVSS／L，添加亚铁离子的条件下，进行半连续试验，硫酸根去除率可迭70％。表明在COD／SO4^2-较低的条件下，各生态因子综合作用下，硫酸盐还原可得较好效果。

| Abstract: | The liquid containing sulfate and sulphite absorbed from flue gas were treated with anaerobic granule sludge. Factors affecting the reduction of sulfate were studied. It concluded that 70% of the sulfate radical was removed in seml-continuous experiments conducted at the following conditions： initial concentration of SO4^2- 800 mg/L, initial ratio of COD/SO4^2- 3.0, initialpH value 7. 0, amount of sludge inoculums 31.10 g VSS/L and adding ferrous ion respectively. It showed that at low ration of COD/SO4^2-, the sulfate could be reduced well with the integrated effects of different ecologic factors. |
