摘　　要：采用改良式UASB反应器与SBR反应器组合对爆破法制浆废液进行了处理,研究结果发现,在厌氧处理段,当水力停留时间为1d时,容积负荷为5.3gCODCr/(L·d),CODCr的去除率可以达到75%,BOD5去除率达95%,平均甲烷产率为247.4ml/gCODCr。组合处理后,废液中BOD5总去除率达98%以上,达到新排放标准,CODCr总去除率为85.3%。The explosion pulping effluent was treated by using the combination of improved UASB reactor and SBR reactor.The results show that during the anaerobic process,when the hydraulic retention time (HRT) is 1 day and the reactor loading is about 5.3g COD Cr /(L·d),the removal rate of COD Cr and BOD 5 can reach 75% and 95% respectively,and the average output of CH 4 is 247.4ml/gCOD.After the combined treatment,the total removal rate of BOD 5 from effluent can achieve 98%,the discharge quantity of BOD 5 per ton o...
