The invention discloses a full-quantitative treatment method for landfill leachate, and belongs to the technical field of sewage treatment. The method comprises the following steps: (1) adjusting the pH value of the landfill leachate, and then carrying out primary anaerobic reaction, primary aerobic reaction, secondary anaerobic reaction and secondary aerobic reaction; (2) feeding the leachate subjected to the anaerobic reaction and the aerobic reaction into a primary sedimentation tank for flocculation and sedimentation; (3) the percolate subjected to flocculation and sedimentation enters an electro-catalysis reactor to be subjected to an electrochemical reaction; and (4) after the electrochemical reaction, allowing the leachate to enter a secondary sedimentation tank for flocculent precipitation so as to complete the degradation of organic matters and ammonia nitrogen. The electrochemical reaction unit is added to the landfill leachate on the basis of anaerobic and aerobic reactions, pollutants in water are
