In this paper, the flow field was established for the branch, ring and mesh water distributors used in the anaerobic reactor for landfill leachate, and the flow state of the wastewater after entering the water distributor is simulated respectively. The effects of main parameters such as different water distributor structure and branch outlet angle on the water distribution effect were discussed. The simulation results show that the flow distribution of each outlet in the annular distributor is the most uniform, and when the angle between the branch pipe and the annular main pipe increases, the flow distribution of each outlet becomes more uniform. When the angle between the branch pipe and the main pipe axis is 60°, the water distribution uniformity is the best.
