Urban reclaimed water treatment and recycling system

The utility model discloses an urban reclaimed water treatment and recycling system which comprises a reservoir, a first treatment unit, a first detector, a second treatment unit, a second detector, a third treatment unit, a flotation circulating water tank, a controller and a plurality of valves. And the three-stage treatment unit is arranged, the treated urban reclaimed water can be used for supplementing flotation ore circulating water, and great environmental protection benefits are achieved. Through the arrangement of the first detector, the second detector and the valves, the valves E-H are manually operated or automatically controlled by the controller, and when the water quality of urban reclaimed water is good, the urban reclaimed water can be directly used as the supplement of flotation ore circulating water after being treated by the first treatment unit or the first treatment unit and the second treatment unit; the equipment use frequency of the second and third processing units is reduced, the se
