The utility model discloses a reclaimed water recycling device for landfill leachate MBR membrane treatment. The reclaimed water recycling device comprises a leachate pipeline, a grid, a pipeline a, an adjusting tank, a pipeline b, a pipeline c, a pipeline d, a self-priming pump, an air blower, a disinfection tank, a recycling pipeline, a reflux pump, a membrane assembly, a membrane biological reaction tank, a facultative tank, a pipeline e and a pipeline f, the leachate pipeline is connected with the grid and is connected with the adjusting tank through a pipeline a; the facultative tank andthe membrane biological reaction tank are of a parallel structure, and leachate passing through the facultative tank enters the membrane biological reaction tank to be continuously treated; a membranecomponent is arranged in the membrane biological reaction tank; by combining the degradation effect of a traditional facultative tank with an advanced membrane separation technology, landfill leachate can be effectively treated and recycled, the membrane bioreactor is small in occupied area and good in effluent quality, a secondary sedimentation tank is not arranged, and operation and maintenanceare simple; residential garbage and domestic wastewater leachate of a community are recycled after being treated, so that the problem of water pollution can be solved, and water resources can be recycled.
