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