Different Sludge Load and Operation Conditions an/OSBRphosphorus Removal Process

Abstract

Based on OSBR discusses different An/water way, different operation condition and different sludge load conditions An/OSBR biological phosphorus removal system effect. Will fill the total phosphorus concentration constant for 10 + 0.5 mg/L, to compare the anaerobic section and outlet TP at the end of concentration. Results show that:①fill aeration compared HeJinShui not aeration, fill not aeration, aerobic rate high, NO-X-Ndecrease, biological dephosphorization effect; ② in different condition operational modes anaerobic and aeration time for 1/4 than than 2/3 cases, biological dephosphorization effect; ③ two temperatures with the COD load of sludge was rised from the enfflect to reduce the concentration of TP, when the sludge COD load≥ 0.46mgCOD/mgMLSS • d, the enfflect TP concentration was lower than 1mg / L; ④ in reaction temperature of 25 °C and 15 °C , 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 °C), y = 2.81 +73.33 x (15 °C);
