摘    要:序批式活性污泥法(SBR)处理污水是一个好氧过程、需氧量与有机物的降解有关。反应器内溶解氧(DO)的变化取决于进浓度、曝气量、污泥浓度等因素。试验研究表明,进水 度高,需氧量大,反应时间长;供气量大,有机降降解快,反应时间短;污泥浓度(MLSS)高,有机物降解快,反应时间短。而以上污水处理过程的特征都可以由反应器中DO变的变化反映,采用DO的在线检测来作为SBR的污水处理过程和终点控制参数是可行的。

关 键 词:序批式活性污泥法  污水处理  溶解氧  COD  控制参数

Abstract:Sequencing batch reactor is an aerobic wastewater treatment process. Oxygen demand is relative to organic matter degradation. Dissolved oxygen in reactor is dependent on concentration of influent, aeration, and MLSS. This experiment and research shows: higher concentration influent needs more oxygen and longer reaction time; higher aeration produced faster organic matter degradation and shorter reaction time; higher MLSS produces faster organic matter degradation and shorter reaction time; DO variation can reflect process and end point of wastewater treatment; and it is feasible to use DO as a control parameter in SBR.
Keywords:sequencing batch reactor  wastewater treatment  DO  COD  control
