Abstract:

The treatment of brewer wastewater was studied using a hybrid anaerobic baffled reactor(ABR), including the steady-state operation performance test, the second start-up behavior test, and the comparative test with the traditional ABR. The results show that the filling material in the hybrid ABR has the obvious good effect on the COD removal with the average COD removal efficiency of 75%. The time interval from the second start to achieving the stable performance for the hybrid ABR is shorter than that of traditional ABR. The performance stability of the hybrid ABR is better than the traditional ABR, the former is characterized by general good performance both during the start-up phase and in the stable operation.
