NOVELTY - Domestic garbage landfill treatment system comprises aeration pretreatment period, methanogenic activity period, garbage stable period, and aeration treatment period comprising 4 reactors (1-4) in which each reactor is connected with gas connecting pipeline (5), upper end of each reactor is provided with inlet and outlet of reflux leachate for collection of methane gas and aeration treatment, bottom of each reactor is provided for collection of permeate, intermittent reactor in aeration pretreatment period is used to conduct garbage, and bottom of reactor is used to collect leachate.    USE - Domestic garbage landfill treatment system (claimed).    ADVANTAGE - Process is environment-friendly and has shortened acidification stage, improved degradation speed, and reduced cost.    DETAILED DESCRIPTION - Domestic garbage landfill treatment system comprises aeration pretreatment period, methanogenic activity period, garbage stable period, aeration treatment period, and 4 reactors (1-4) in which each reactor is connected with gas connecting pipeline (5), upper end of each reactor is provided with inlet and outlet of reflux leachate for collection of methane gas and aeration treatment, bottom of each reactor is provided for collection of permeate, intermittent reactor in aeration pretreatment period is used to conduct garbage, bottom of reactor in methanogenic activity period is used to collect leachate, upper methanogenic environment is gradually expanded to garbage layer of reactor, bottom of reactor in aeration pretreatment period is connected with stable leachate collecting port, stable leachate collecting port in aeration pretreatment period is connected with inlet of reactor, aeration treatment period is performed on reactor, and domestic garbage is continuously treated in aeration treatment period. An INDEPENDENT CLAIM is included for treatment of domestic garbage landfill which involves filling domestic garbage into 1st reactor, entering into aeration pretreatment period, intermittently aerating, stop aerating, entering into methanogenic activity period, collecting permeate having pH of greater than or equal to 7 at bottom of reactor, refluxing leachate, gradually expanding methanogenic environment to garbage layer of reactor, starting 2nd reactor, crushing domestic garbage, loading into 2nd reactor, intermittently aerating, stop aerating, entering into methanogenic activity period, collecting permeate having pH of greater than or equal to 7 at bottom of reactor, refluxing leachate, gradually expanding methanogenic environment to garbage layer of reactor, starting 3rd reactor, entering into aeration pretreatment period, stabilizing methane content of garbage in 1st reactor, collecting permeate, returning to 1st reactor, inoculating methane, providing organic matter, stop aerating, entering into methanogenic activity period, collecting permeate having pH of greater than or equal to 7 at bottom of reactor, refluxing leachate, gradually expanding methanogenic environment to garbage layer of reactor, starting 4th reactor,entering into aeration pretreatment period, stabilizing methane content of garbage in 2nd reactor, collecting permeate, returning to 2nd reactor, inoculating methane, providing organic matter, entering domestic garbage from 1st rear reactor into aeration treatment, and using continuous aeration treatment.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of domestic garbage landfill treatment system. (Drawing includes non-English language text).    Reactor (1-4)    Reactor is connected with gas connecting pipeline (5)
