METHOD FOR PURIFYING LEAKAGE WATER IN OCEAN RECLAIMED LAND BY USING MULTI-LAYERED FILTERING MEMBER |
摘要 |
PURPOSE: A method is provided to purify leakage water generated in an ocean reclaimed land by removing sulfuric compound and contaminated stuff from the leakage water using a multi-layered filtering member. CONSTITUTION: A first filtering fabric layer including a first filtering fabric having water permeability of 0.05-0.15cm/sec and a filtering material surrounded by the first filtering fabric is positioned at front and rear portions of a second filtering fabric layer including a second filtering fabric having water permeability of 0.01-0.0001cm/sec and an absorption agent surrounded by the second filtering fabric. A third filtering fabric having water permeability of 0.1-0.01cm/sec is filled between the first and second filtering fabric layers. The filtering material includes at least one selected from the group consisting of sands, gravels, and pulverized stone.
