METHOD AND APPARATUS FOR TREATING LEACHED WATER IN LANDFILL SITE

摘要

PPROBLEM TO BE SOLVED: To treat leached water from a landfill site at a low operation cost by a small-sized apparatus while suppressing environmental pollution low. PSOLUTION: The leached water is treated in a biological treatment device 2 so as to remove various organic components contained in the leached water. Subsequently, this leached water is evaporated/concentrated in evaporators 10 and 12, and the concentrated liquid from the evaporaters is then treated in a solid-liquid separator 16 so as to separate/remove the solid component in the concentrated liquid while the condensed water from the evaporators are sprayed into the atmosphere by sprayers 19a, 19b and 19c to be diffused/evaporated in the atmosphere.
