摘要：
Split-feed anaerobic baffled reactor (SABR) is a novel reactor based on the design concept of anaerobic baffled reactor (ABR). The tracer test of hydrodynamic characteristics of SABR was studied and the impact of characteristic section on hydrodynamic characteristics of SABR was analyzed. Residence time distribution (RTD) studies with deionized water at the same hydraulic residence time (HRT) of 5 h were carried out to investigate the dead spaces and mixing patterns in SABR under different effluent recycling ratios and the inlet proportions. The results showed that the hydrodynamics of reactor were influenced by changing the effluent recycling ratio or the inlet proportion. The volume of dead space and the values of N decreased with the effluent recycling ratio increasing and the hydraulic flow of SABR tended to be completely-mixed pattern, also with changing the inlet proportion from 1: 1: 1: 1: 1 into 5: 4: 3: 2: 1.
