摘要
改良序批式活性污泥法(Modified Sequencing Batch Reactor,MSBR)处理污水主要是一个好氧过程,需氧量与有机物的降解有关。反应池内溶解氧(DO)的变化取决于进水的浓度、曝气量、污泥浓度等因素。试验研究表明,进水浓度高,需氧量大,反应时间长；供气量大,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池中DO的变化来反映,采用DO的在线检测来作为MSBR的污水处理过程和终点控制参数是可行的。
Modified Sequencing batch reactor is anaerobic mostly in 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 in fluent needs more oxygen and longer reaction time;higher aeration produced faster organic matter degradation and shorter reaction time; DO variation can reflect process and endpoint of wastewater treatment;and it is feasible to use DO as a control parameter in MSBR.
