The blockage of water supply and drainage devices by pollutants can affect the flow rate of water bodies,reduce the load ca-pacity of the water supply and drainage system on water resources,and cause the problem of untimely water flow scheduling.In response to the problem of pollutant blockage in water supply and drainage systems,a method for identifying pollutant blockage in water supply and drainage systems based on ultimate flow velocity and bearing capacity was designed.The structural model of the water supply and drainage device was improved,the standard for the ultimate flow velocity of the water body and the bearing capacity of the device equip-ment on the flowing water body was determined,and the analysis of the maximum flow velocity and bearing capacity of the water body was completed.The situation of pollutant blockage was studied,the location of the blockage in the water transfer area was located,and the identification of pollutant blockage in the water supply and drainage device based on the ultimate flow rate and bearing capacity was completed.The experimental results indicate that this method can determine the intensity of pollutant blockage behavior based on the water flow velocity value.After identification,the flow rate of the water supply and drainage system is maintained within 5.25-6.00,3.75-4.50,and 1.50-3.00 m/s,respectively,under the blockage of level Ⅰ,Ⅱ,and Ⅲ pollutants,effectively avoiding blockage of the wa-ter supply and drainage system.
