Abstract

Based on SBR we discussed on biological removal phosphorus system. In the reaction temperature at 15 and 25 under the conditions of influent COD/TP ratio and COD load of sludge. Total phosphorus concentration of influent was be constant for 10 ± 0.5mg / L, compared to anaerobic paragraph at the end of the water and TP concentration. The results showed that: Under both temperature conditions the effluent TP concentration is reducing with the influent COD/TP ratio increase, especially when the influent COD/TP ratio is more than or equal to forty, the effluent TP concentration is below1 mg/L. Two temperatures with the COD load of sludge was risen from the effect to reduce the concentration of TP, when the sludge COD load 0.46mgCOD/mgMLSS • d, the effluent TP concentration was lower than 1mg / L; In reaction temperature of 25 and 15 , the amount of anaerobic releasing paragraph and COD load of sludge are very good correlation, linear relationship between the two were: y = 0.72 +71.91 x ( 25 ), y = 2.81 +73.33 x (15 ); In the COD load of sludge under the same conditions, the removal rate in 15 is higher 5% than the one in 25 ; The effluent of aeration rate on the phosphorus removal efficiency of SBR system was investigated, which showed that the aeration rate was an important factor affecting the activity of poly. Increasing the aeration rate will greatly increase the phosphorus uptake efficiency of the phosphorus accumulating bacteria, and increase the phosphorus removal efficiency.
