It can optimize the design of sewage pipe network system and select the design conditions of pipe network to obtain the best hydraulic characteristics and the most economical design plan by studying the hydraulic characteristics of sewage pipe network under different conditions. In this paper, k-s turbulence model is used to calculate the change of energy consumption characteristics in sewage pipe network under different working conditions. The results show that the pipe diameter is too small and the pressure on the pipe wall increases, which is not conducive to flood discharge. If the inlet velocity is too small, the negative slope of the pipe would lead to the reduction of the overall flow rate, which is easy to cause siltation of the sewage pipe network. Proper pipe diameter, inlet velocity and reasonable slope can help the pipe drain water. Increasing the diameter of the main pipe can improve the stability of the fluid, which is more conducive to sewage discharge.
