摘要:介绍了蔗渣制浆废水好氧生化处理系统中厌氧预处理技术，简述了该技术的工艺流程、技术参数、运行情况以及技术优势。在好氧系统前段进行厌氧预处理后可降低废水高浓度COD_Cr，进一步去除无机固形物，确保了好氧系统的稳定运行，提高氧化沟去除效率，降低了深度处理运行费用。

Abstract:The application of anaerobic pretreatment in aerobic biochemical treatment of bagasse pulping effluent was introduced in the paper, the technological process, technical parameters, operation condition, and technological advantage were presented. The anaerobic pretreatment could reduce COD and SS， ensured that the stable operation of aerobic system, improved the efficiency of oxidation ditch. It played an important role in reducing cost of advanced treatment system.
