PROBLEM TO BE SOLVED: To provide a method and an apparatus for rendering a liquid containing harmful components such as various organic contaminants, malodorous components and bacteria harmless. SOLUTION: The method for treating the harmful component-containing liquid comprises: a step (A) of adding a water-soluble oxidizer, a mixed solution of the water-soluble oxidizer with a dissolvable water-soluble oxidizer or a mixed solution of the water-soluble oxidizer with dissolved ozone to the harmful component-containing liquid and mixing the resulting liquid; a step (B) of making the resulting liquid flow through a packed column in which at least one adsorbent selected from the group of (1) pentasil zeolite, (2) zeolite beta, (3) ultrastable Y-type zeolite (USY), (4) mesoporous silicate, (5) ultrastable mordenite and (6) silica gel, each of which adsorbs the water-soluble oxidizer or the mixed solution of the water-soluble oxidizer with dissolved ozone and the harmful components, is packed; and a step (C) of rendering the harmful components contained in the liquid harmless by the action of the water-soluble oxidizer or the mixed solution of the water-soluble oxidizer with dissolved ozone.
