摘　　要：以人工配制的含硫酸盐有机废水作为原水,研究不同COD/SO42-值下厌氧折流板反应器(ABR)处理含硫酸盐有机废水去除率。试验结果表明:当COD/SO42->14.8时COD的去除率可达95%,SO42-的去除率在86%～90%之间;当COD/SO42-在14.8～4.0之间时,COD的去除率有所下降但仍能保持在94%以上,SO42-的还原率基本稳定在96%～99%之间;当COD/SO42-在2.4～2.0之间时,COD和SO42-的去除率均由90%下降至85%。各隔室的硫化物随COD/SO42-值的减小呈不断增加的趋势,当各隔室硫化物浓度>100 mg/L时,COD和SO42-的去除率呈明显下降趋势。不同的COD/SO42-值对各隔室VFA浓度影响较小,pH随COD/SO42-值的减小呈逐渐上升趋势。Effect of COD/SO42-on anaerobic baffled reactor（ABR） for treatment of organic wastewater containing sulfate was investigated.Results showed that when COD/SO42-was above 14.8,COD removal rate was over 95% and sulfate removal rate was between 86% and 90%.When COD/SO42-was between 4 and 14.8,COD removal rate was remained above 94%,and sulfate removal rate was between 96% and 99%.When COD/SO42-was between 2.0 and 2.4,COD and sulfate removal rate both were decreased from 90% to 85%.Sulfide of each compartment had a rising trend with COD/ SO42-reduced,when sulfide of each compartment was higher than 100mg/L,COD and sulfate removal rate decreased significantly.Effect of different COD/SO42-on VFA concentration of each compartment was less,with reducing COD/ SO42-,pH was increased gradually.
