| 摘 要： | 通过建立交互式反应器在改良A2/O运行模式下的能量流,对能量的流向和变化进行了分析;考察了该工艺在5种不同运行工况下的单位流量比能耗和单位污染物比能耗,从而为能效评估提供了依据.通过对内回流比、污泥回流比和好氧池溶解氧浓度这三个操作参数与系统比能耗进行回归分析,得到了其线性关系式.采用ASM1模型对各工况进行模拟,确保在出水水质达到GB 18918--2002一级B标准的基础上,系统的比能耗最低.结果表明,系统在改良A2/O模式下运行,当各参数值取下限时系统的比能耗最低;各运行参数按对系统比能耗的影响程度排序为:曝气量>内回流比>污泥回流比.

| Abstract: | The energy flow of interactive reactor operated in the modified A2/O process was established to analyze the flow and variation of energy in the system.The specific energy consumption of the system in 5 operation conditions was compared to provide the basis for efficiency evaluation.The regression analysis between specific energy consumption and three operation parameters,internal recycle ratio,sludge return ratio and DO concentration in the aerobic tank was performed,and a linear relationship was obtained.T... |
