The invention discloses a full-quantitative treatment device for landfill leachate. The full-quantitative treatment device for the landfill leachate aims to overcome the defect of MBR binding strong aeration in existing full-quantitative treatment equipment for the landfill leachate. The system comprises a pretreatment filtering unit, a softening and hardness-removing treatment unit, a nitrogen and phosphorus removal unit, an MBR (membrane bioreactor) unit, an oxidation unit and a clean water tank which are sequentially connected, the pretreatment filtering unit is used for adjusting the physical and chemical properties of the landfill leachate and filtering suspended matters and large-particle pollutants in the landfill leachate; the nitrogen and phosphorus removal unit comprises an anaerobic reactor, an anoxic reactor, an oxygen exposure reactor and an oxygen exposure sedimentation tank; the membrane assembly is provided with a water outlet pipe, and the water speed detection device detects the water outlet
