The Removal Phosphorus Effect In different Temperature in An/OSBR
The purpose of this paper is to discuss influent COD/TP ratios on Biological Phosphorous Removal System under the reaction temperature at 15℃ and 25℃ in An/OSBR. When influent total phosphorous(TP)concentration was maintained at 10±0.5mg/L, they were compared at the end of anaerobic and effluent. The results show that under both temperature conditions the effluent TP concentration is reducing with the influent COD/TP ratio increasing, especially when the influent COD/TP ratio is more than or equal to forty, the effluent TP concentration is below lmg/L. There are unexceptionable correlations between anaerobic P-release and the influent COD/TP ratio too, they are y=2.05+0.78x(25℃), y=3.07+ 0.83x(15℃). TP removal efficiency at 15℃ is 5% more than at 25℃ with the same influent COD/TP ratio.
