摘　　要：通过试验考察了采用厌氧折流板反应器(ABR)处理高浓度硫酸盐废水时,COD/SO42-值对厌氧消化过程的影响。结果表明:COD/SO42-值可作为ABR反应器运行的重要参数,维持进水COD/SO42-值≥2.5,可保证系统的正常运行;当3.3≤COD/SO42-≤20时,反应器运行状况较好,对COD和SO42-均能保持较高的去除率。The effect of COD/SO4^2- ratio on anaerobic digestion in high strength sulfate wastewater treatment using anaerobic baffled reactor （ABR） was investigated through experiments. The results show that COD/SO4^2- ratio is one of the crucial parameters for ABR running. The system is in normal operation when the influent COD/SO4^2-ratio is equal to or above 2.5. When COD/SO4^2- ratio is between 3.3 and 20, the reactor runs well, COD and SO4^2- removal efficiencies are both effective.
