The invention discloses double-side-washing drinking water disinfection equipment for livestock breeding. The equipment structurally comprises a center bottom column, outer pressure cleaning structures, a water drinking device, a base, a water flushing structure and a shell body; the center bottom column is vertically arranged right on the center of the bottom surface of the inner part of the outer shell through the base; the outer pressure cleaning structures are arranged under the top surface of the outer shell and right above the center bottom column; the water flushing structure is arranged right in the center of the bottom of the base; the water drinking device is movably installed between the outer pressure cleaning structures and the central bottom column. According to the equipmentprovided by the invention, the center bottom column, the outer pressure cleaning structures and the like are matched with each other, and high-speed flushing is matched with centrifugal washing, so that the water drinking device is flushed from a forward side and a reverse side. In addition, water after washing does not remain on the outer shell, and water on the surface of the water drinking device can be centrifugally spin-dried by rotating, so that drying can be achieved more easily, cleaning can be achieved through one-time flushing, residual dirt at dead corners is not easily exists.
