摘　　要：采用厌氧折流板反应器(ABR)对废纸制浆造纸废水进行水解酸化预处理,研究结果表明:水力停留时间和进水pH值对悬浮物(SS)的去除效果影响不大,酸性条件下对CODCr的去除效果优于碱性和中性条件。当水力停留时间为8h时,ABR反应器出水的BOD5/CODCr可达0.55;当进水pH值为6时,ABR出水的BOD5/CODCr可达0.56。在最佳工艺条件下连续运行1个月,废水CODCr、SS的去除率分别稳定在40.5%、90.7%左右,BOD5/CODCr值由0.42提高到0.53,为后续好氧生化处理提供了有利条件。Hydrolytic acidification pretreatment was conducted to treat the effluent from pulp and papermaking using wastepaper by ABR. q-he research results showed that the change of hydraulic retention time （HRT） and pH value have little impact on the removal efficiency of SS, the acidic condition is better than the neutral and alkaline condition for the removal of CODCr. The BODs/ CODcrratio reaches to 0.55 when the HRT is 8 h, the BODs/CODCr ratio reaches to 0.56 when the pH value is 6. The reactor runs continuously for a month under the optimum conditions, about 40.5% of CODCr and 90.7% of SS can be removed respectively, and the BOD5/CODCr ratio increases from 0.42 to 0.53 which is favorable for the subsequent aerobic biological treatment.
