- Abstract:
- An integrated process of enhanced nitrogen and phosphorus removal from mixed municipal wastewater by membrane Bioreactor was studied. The results showed that the effect of reflux ratio on COD and NH3-N was not significant, and the average removal rate of TN gradually increased with the increase of reflux ratio, when the reflux ratio increased from 1.5 to 2.0, with the increase of reflux ratio, the removal rate of TP increased from 2.0 to 3.0, and the average removal rate of TP decreased with the increase of reflux ratio, the average removal rate of TP was the highest when the reflux ratio was 2.0. The optimum reflux ratio is 2.0.0.
