The invention relates to a landfill leachate high-performance denitrification system and denitrification process thereof. A movable bed membrane bio-reactor is combined with a denitrification pool ofthe active sludge membrane bio-reactor. For the landfill leachate with sufficient carbon source on the front end, the landfill leachate high-performance denitrification system comprises a core structure of the denitrification pool combined with the movable bed membrane bio-reactor, the denitrification pool and a hyperfiltration membrane; for the landfill leachate with insufficient carbon source onthe front end, the landfill leachate high-performance denitrification system comprises a primary denitrification pool, the denitrification pool combined with the movable bed membrane bio-reactor, a secondary dentrification pool and a hyperfiltration membrane; and for the landfill leachate with high denitrification requirement, the landfill leachate high-performance denitrification system comprises a core structure of a fr
