Zusammenfassung: | The invention relates to a treatment method for accelerating stabilization of landfill garbage. The method comprises the following steps: enabling mature leachate generated in a landfill column to pass through a hydrolytic acidification pool, carrying out hydrolytic acidification treatment on the leachate, determining BOD5 and COD in the leachate, and refilling the leachate into a landfill pile body when the BOD5/COD is greater than 0.3; and after the leachate is recharged into the landfill body and biodegraded for 1-2 days, trace aeration is carried out on the landfill pile body from bottom to top at the flow rate of 50-100 L/h, and the aeration time is 10-15 min. According to the method disclosed by the invention, degradation of the landfill is promoted mainly through two technical means of a pretreatment technology before leachate recharge and trace aeration, and the stabilization process of the landfill is accelerated.
