Effect of C/N on simultaneous nitrogen and phosphorus removal in Carrousel 2000 oxidation ditch
C/N对Carrousel 2000氧化沟同步脱氮除磷的影响研究

The effect of C/N ratio on simultaneous nitrogen and phosphorus removal in Carrousel 2000 oxidation ditch was studied.The experimental results show that when the influent C/N ratio was between 5 and 13,ammonia nitrogen removal efficiency in oxidation ditch was not affected by influent C/N ratio.The ammonia nitrogen concentration in the effluent was below 1 mg/L,the average removal rate was 97.40%.When influent C/N ratio was lower than 11,TN and TP removal rates increased sharply as C/N ratio increased,from ...
