摘　　要：采用厌氧折流板反应器(ABR)处理赤糖废水,考察其在不同进水容积负荷下的启动情况。结果表明:在(35±1)℃条件下,经历60天成功地完成对ABR反应器的启动。进水COD容积负荷由1.0kgCOD/(m3·d)增加到6.0kgCOD/(m3·d),COD的去除率达到85%,pH值和氧化还原电位(ORP)也达到要求。通过采用不同进水容积负荷启动ABR,证明ABR成功启动的前提是进水COD容积负荷不宜过高,启动初期过高的COD负荷会使反应器内酸性物质大量积累,导致启动失败。Anaerobic baffled reactor （ABR） was used to treat blackstrap molasses wastewater and start up at different influent COD volumetric loadings was investigated.Start up at （35 ± 1）℃ was completed in 60 days.At influent COD volumetric loading from 1.0kg COD/（m3 · d） to 6.0kgCOD/（m3 · d）,COD removal rate reached 85％,and pH value and redox potential （ORP） also met the requirements.Start up by using different influent COD volumetric loadings proved that influent COD volumetric loading should not be too high.Overly high COD loading caused acid accumulation in the reactor,leading to failure of start up.
