摘要： PROBLEM TO BE SOLVED: To provide an economical cleaning treatment method and a cleaning treatment apparatus of steel slag landfill site leachate, for enabling steel slag to be effectively utilized for landfill without causing environmental contamination, and contributing to environmental protection and resource protection by improving and ensuring the cleaning treatment technique of leachate from the steel slag produced when the steel slag is utilized for the landfill.SOLUTION: A cleaning treatment method of the steel slag landfill site leachate is for cleaning leachate (raw water) from a landfill site where steel slag is used for landfill, and at least includes a step of performing oxidation treatment by adding hypochlorous acid to the raw water which is water to be treated, then performing coagulation treatment by adding an inorganic coagulant and a polymer coagulant to the water to be treated to coagulate suspended solids in wastewater, and then performing solid-liquid separation. Also, before adding the polymer coagulant, air diffusing treatment is performed by sending air to the water to be treated from a diffuser pipe. The cleaning treatment apparatus of the steel slag landfill site leachate is used for performing the method.
