【摘要】 SBR法能灵活地根据所处理废水浓度的不断变化 ,改变其反应时间 ,深圳下坪渗滤液处理厂试运行进行了以DO作为SBR法反应时间控制参数的研究 ,结果表明 :污泥浓度在 2 .5～ 3g/L ,进水COD在 0 .8～ 1.1g/L时 ,进行曝气都会在反应开始后几小时内出现所谓“平衡DO”现象 ,随着硝化进程的结束 ,CO浓度迅速地大幅度升高 ,用DO作为SBR反应器在线控制是可靠的。更多还原

【Abstract】 Many experiments show that with MLSS of 2.5～3g/L and influent COD of 0.8～1.1g/L the phenomenon of balanced DO can occur within several hours after the reaction and later DO concentration goes up quickly with the end of nitration.So it is reliable to use DO as fuzzy control parameter for SBR process.更多还原
