Pressure-Flow and Free-Flow Discharge Modes in Closed-Loop Sewage Systems

[摘要] The paper discusses flow modeling in closed-loop sewage systems. These systems take place in reconstruction and development of sewage systems. The waste flow values which are distributed over individual closed-loop sewers are proposed to be determined on the basis of the solution of the conservation equation for mass and energy. This article presents these equations for the cases of pressure-flow and free-flow of drains and calculating examples of all these cases. The issues of improving the reliability of sewage systems by transferring them to a closed-loop structure are considered.
