两种污水处理工艺MBR和AAO的出水水质分析对比

Comparison of Effluent Quality Analysis Between Two Sewage Treatment Processes MBR and AAO

针对目前污水处理厂广泛应用的两种处理工艺MBR和AAO,本文选取了太原市某污水处理厂一段时间经过MBR和AAO两种处理工艺处理前后的出水样本,通过化学需氧量、总氮、总磷和氨氮的水质检测指标分析对比,对两种工艺的水质处理效果进行了比较和评价。结果显示经过MBR工艺处理后出水水质中4个指标的测定值均低于AAO工艺,说明MBR工艺的去除效果优于AAO工艺,MBR工艺能够更有效地降解有机污染物和氮磷等无机污染物,具有更好的处理效果。

In response to the two widely used treatment processes MBR and AAO in current sewage treatment plants,this article selected effluent samples from a sewage treatment plant in Taiyuan City before and after treatment with MBR and AAO for a period of time.By analyzing and comparing the water quality detection indicators of chemical oxygen demand,total nitrogen,total phosphorus,and ammonia nitrogen,the water quality treatment effects of the two processes were compared and evaluated.The results showed that the measured values of four indicators in the effluent water quality after MBR process treatment were lower than those of AAO process,indicating that the removal effect of MBR process is better than that of AAO process.MBR process can more effectively degrade organic pollutants and inorganic pollutants such as nitrogen and phosphorus,and has better treatment effect.
