【摘要】 结合郑州市马头岗污水处理厂的运行情况,对比分析了倒置A2/O工艺与UCT工艺的运行效果。结果表明,倒置A2/O工艺与UCT工艺对污水中COD、BOD5、SS、NH3-N的去除效果并无明显差异,两种工艺对这些指标的去除率都较高,月平均去除率都能达到90%以上,但两种工艺对TP和TN的去除效果略有差异,倒置A2/O工艺对TP和TN的去除率高于UCT工艺主要是受进水碳源和混合液回流等条件影响所致。更多还原

【Abstract】 Based on the running conditions of Matougang Sewage Treatment Plant,the comparative analysis of operation efficiency between the reversed A2/O process and the UCT process was performed.The results show that there is no significant difference in removal of COD,BOD5,SS and NH3-N.In the two processes,the removal rates of these indicators are higher,and the monthly average removal rates can reach more than 90%.However,the two processes have slight difference in the removal of TP and TN.The removal rates of TP and TN in the reversed A2/O process are higher than those in the UCT process,which is due to the influence of influent carbon source and mixed liquid return.更多还原
