The well washing process of in-situ leaching uranium mine is an important means to increase the amount of drilling water. However, a large amount of impurities such as sediment in the well washing wastewater cause the bag filter and adsorption tower pressure to rise, which indirectly affects the production progress. Based on the principle of centrifugal force, a sand removal device for well washing wastewater was developed and applied in a certain in-situ leaching uranium mine. The results show that it can reduce the pressure of bag filter and adsorption tower, reduce the frequency of filter bag replacement, increase the adsorption water and increase production capacity. The sand removal device of the well washing wastewater has a certain popularization value in the drilling and well washing technology of in-situ leaching uranium mine.
