摘　　要：在中温30～35℃条件下,厌氧序批式反应器(ASBR)对垃圾渗滤液进行厌氧预处理,结果表明:较高的进水COD和OLR条件下,反应器有着更好的处理效果;相近的OLR条件下,较长的HRT有更好的COD去除效果;OLR较低时,进水时间/反应时间(tF/tR)越大,COD去除效果越好;OLR较高时则需要较小的tF/tR;COD去除率随进水NH4+-N/COD的升高有明显的下降趋势;垃圾渗滤液COD/SO24-在5.52～11.41,反应器中不但有甲烷产生,同时也有硫酸盐的还原发生,SO24-去除率最高可达到77%。Anaerobic pretreatment of municipal landfill leachate was evaluated using lab-scale anaerobic sequencing batch reactor(ASBR)at 30～ 35 ℃.The following conclusions were drawn from the study:ASBR had better COD removal rate when COD and OLR were higher relatively;higher COD removal rate could be got in larger HRT at the similar OLR conditions;larger COD removal rate corresponded to bigger t _F/t _R when OLR was lower.At higher OLR the result was opposite;COD removal rate was evidently decreased with the increase in NH+_4-N/COD of influent.The COD/SO 2-_ 4 was ranged from 5.52 to 11.41,the sulfate reduction efficiency could reach to 77%,so there was not only methane production but also sulfate reduction in ASBR.
