EPANET与SWMM水质模块在河网水循环中的联合应用OACSTPCD

The water quality improvement project of river network water bodies,whether it is internal water circulation or external water replenishment,how to reasonably determine the location and scale of replenishment points,involves the overall investment scale and the efficiency of water purification,which are the key and difficult points of the project.This paper combines the example of a river network water environment treatment project in a development zone of a certain city.Firstly,assuming the overall scale,an EPANET water supply module is used to establish a replenishment pipeline network model,select the pump head and flow rate,and allocate the water volume of each replenishment outlet.Then,a water cycle model of the river network is established through SWMM to verify water quality changes and calculate the cycle period.If the demand is not met,then adjust the scale of water replenishment.Through such a feedback system and repeated calculations,the scale of the water replenishment pipeline network and water inlet can be optimized,and appropriate scale,flow rate,and pipe diameter can be obtained.This time,two simple and free software modules were used to quickly achieve the optimization of river network water replenishment and water circulation,which can provide useful reference for similar projects in the future.
