The invention discloses an advanced treatment process for kitchen waste fermentation waste liquid. The process includes: (1) adding a coagulant and a flocculant into kitchen waste fermentation waste liquid and performing coagulation pretreatment to obtain a treatment liquid I; (2) conducting UASB anaerobic treatment on the treatment liquid I to obtain a treatment liquid II; (3) carrying out contact oxidation treatment on the treatment liquid II to obtain a treatment liquid III; (4) introducing the treatment liquid III into a biozeolite bed-membrane bioreactor to carry out biological membrane reaction so as to obtain a treatment liquid IV; (5) subjecting the treatment liquid IV, a titanium alloy catalyst, Fe<2+> and H2O2 to four-phase catalytic oxidation reaction so as to obtain a treatment liquid V; and (6) subjecting the treatment liquid V to flocculation and precipitation, thus obtaining discharged effluent water. The process provided by the invention combines UASB with two-stage aerobic biological technology, and adds the coagulation pretreatment and four-phase catalytic oxidation advanced treatment to achieve effective removal of difficultly degradable pollutants from high concentration kitchen waste fermentation waste liquid, ensures stable effluent water, and realizes ultralow pollution concentration discharge of combined process effluent water.
