Leachate resourceful treatment method and equipment

The invention provides a leachate resourceful treatment method and equipment. The leachate is subjected to material separation, and humic acid obtained after material separation is subjected to low-temperature concentration treatment to form a solid humic acid fertilizer; deamination treatment is performed on the leachate subjected to material separation through a gas separation membrane; aerobictreatment is performed on the leachate subjected to deamination treatment to obtain aerobic produced water and aerobic sludge; membrane filtration treatment is performed on the aerobic produced waterto obtain filtered concentrated water; further concentrating and purifying are performed the filtered concentrated water to obtain a concentrated solution and concentrated solution sludge; the concentrated solution is evaporated; and potassium chloride purification treatment and sodium chloride separation treatment are respectively performed on the concentrated solution subjected to evaporation treatment to obtain potassiu
