| Abstract: | By using the sequencing batch reactor,the aerobic granular sludge was successfully cultivated,and the optimal conditions were studied.The air pump and the first gas sand core are used,the aeration was controlled by a gas rotor flow meter.The aeration capacity was 0.20 m3 / h,its settling time 20~30 min,at room temperature of 12 ~ 22 ℃,the pH value was 7.0±0.1.Influent NH4+-N and TP concentrations were 200 mg/L,60 mg/L respectively,COD volume load was 5.87 kg COD/(m3·d),the removal rates of COD,TP reached 90% and 83% respectively,the removal rate of the NH4+-N was 87%. |
