Effect of the sludge granulation on nitrogen and phosphorus removal in SBR process
|
Abstract:
The removal efficiency of P and N and settlement characteristics of sludge were studied in SBR process by using synthetic domestic wastewater as feed. It is found that the aerobic granular sludge was formed in the reactor under the proper operating conditions, which can show excellent settling ability. The sludge is mainly 0.2-1.0mm in diameter and 50 of SVI. Compared with the experimental results before sludge granulation, the removal efficiencies of COD, P, NH3-N and TN are highly improved, It can remove P and N simultaneously with 90% removal for COD, 85% for P, 90% for NH3-N, and 80% for TN.
