description The invention belongs to the field of wastewater treatment, and relates to an aged refuse landfill leachate treatment system; an adjusting tank communicates with a liquid inlet of an MBR treatment system, and a permeate liquid outlet of the MBR treatment system communicates with a two-stage DTRO treatment system; a concentrated liquid outlet of the two-stage DTRO treatment system communicates witha liquid inlet of an HPRO treatment system; a permeate liquid outlet and a concentrated liquid outlet of the HPRO treatment system respectively communicate with a permeate liquid treatment system andan evaporation system. The invention further provides a leachate treatment method; leachate is sequentially treated by the MBR treatment system, the two-stage DTRO treatment system and the HPRO treatment system, an obtained concentrated liquid enters the evaporation system to be treated and then is safely buried, and a permeate liquid is sequentially treated by a two-stage RO treatment system andan ion exchange resin devi
