Circular ring pond of desilting filter to sediment is a new type of desilting and filtrating equipment, the paper studied the physical model test of circular ring pond of sediment desalting filter in urban industrial water supply project of Hutu town of Xinjiang, simulated the operation effect under the condition of 1m3/s.The results show that the three filter materials of different particle size can better play a role in sand filtration, drainage filter and keep from the breakdown when the center overflow tube is heightened at 0.4m. At the same time, the equipment can meet the requirement of the amount of water diverted. The average flow velocity of busbar trunking is between 0.88and 2.77m/s.Compared with the common water and sediment separation device, the equipment realized the target of energy-saving,emission reduction and sediment environment-friendly dealt with, and can provide a new idea for the separation of water and sediment.
