纯氧曝气与空气曝气处理生活污水的效果比较

Compared with the Treatment Effect of Pure Oxygen Aeration Active Control Oxygen Reactor and Air Aeration

研究纯氧曝气与空气曝气对好氧装置处理生活污水效果以及对NH3和H2S产生量的影响。试验结果表明,与空气曝气相比,纯氧曝气的COD去除率高2.57%,NH3-N去除率高9.59%;处理7L相同体积的污水,空气曝气吹脱出的NH3是纯氧曝气的3.4倍,吹脱出的H2S平均值为12.99 ug,远大于纯氧曝气装置的0.38 ug。

The study of the different affects of the pure oxygen aeration and air aeration on the oxygen reactor＇s treatment effect,NH3 and H2S.The results show that The pure oxygen aeration has the higher removal rate of COD and NH3-N than air aeration,by 2.57% and 9.59%.As the same 7L wastewater,the output of NH3 from pure oxygen aeration was 3.4 times than air aeration.And the output of H2S was 0.38ug less than 12.99ug form pure oxygen aeration.
