Treatment method of landfill leachate concentrated solution

The invention provides a landfill leachate concentrated solution treatment method, which comprises the following steps: solid-liquid separation, microbial inoculum treatment, deamination, electrolytic purification, electro-photocatalytic oxidation, effective reduction of COD in the concentrated solution, introduction of ozone into a deamination membrane, improvement of the degradation speed of macromolecular organic pollutants, and reduction of the COD in the concentrated solution. Meanwhile, the ozone and free radicals generated by the ozone can also relieve pollution of the deamination membrane, organic or inorganic pollutants in the wastewater are coagulated through electrolytic purification and are separated from the wastewater, the purification effect is further improved, the electrolyzed water is subjected to oxidation treatment through combined electric-photocatalytic oxidation, flocculates or oil can be cleared away, and the water quality is improved. A large amount of humus, protein or polysaccharide
