摘　　要：为避免在两相厌氧处理工艺中设置pH调节单元,在中温（35℃）条件下,采用改进型酸化反应器处理含硫酸盐酸性有机废水,考察了其处理效果。结果表明,在进水pH值为5.5、COD/SO4^2-值为4.8的条件下,出水pH值为6.9～7.2、COD/SO4^2-值为9.2～12.5,水质可满足后续产甲烷反应器对进水的要求。In order to avoid setting pH regulating unit in two-phase anaerobic treatment process,a modified acidification reactor was applied to treat the acidic organic wastewater containing sulfate under mesophilic condition（35 ℃）,and the treatment efficiency was investigated.The results show that under the condition of influent pH of 5.5 and COD/SO4^2- of 4.8, the effluent pH is 6.9 to 7.2 and COD/SO4^2- is 9.2 to 12.5.The effluent quality can meet the requirement of the subsequent methanogenic reactor for the influent.
