The utility model relates to a factory landscape water circulation system. The factory landscape water circulation system comprises a factory process water tank (1), a circulation water pump (2), a landscape water tank (3), a landscape water channel (5) and a pipeline (7). The factory process water tank (1) is arranged on a position higher than the topography of the landscape water tank (3). The landscape water channel (5) is arranged between the factory process water tank (1) and the landscape water tank (3). Water of the factory process water tank (1) naturally flows into the landscape water tank (3) through the landscape water channel (5). Both the pipeline (7) and the circulation water pump (2) are also connected between the factory process water tank (1) and the landscape water tank (3). The section shape of the pipeline (7) is a circle or an oval or a rectangle. Redundant water of the landscape water tank (3) is pumped back to the factory process water tank (1) through the pipeline (7) by the circulation water pump (2). Therefore, circulation of factory landscape water is formed and effect of beautifying environment is increased.
