Abstract：To analyze the impacts of the nozzle density, inlet diameter and nozzle angle with fixed HRT (Hydraulic Retention Time), parameterized models of distributor were set up. The reciprocal of the velocity’s standard deviation in the selected plane was used as the reference index while the single factor and orthogonal analysis were carried out with Fluent software. The results showed that when the diameter of the inlet diameter was 110 mm, the nozzle number was 6, and the nozzle angle was 30°, the uniformity of the inlet water was optimized, and was helpful to improve the sewage treatment effect.
