Oil adsorbent and oil water treatment method and oil water treatment filter and oil water treatment equipment

摘要

To provide an oil adsorbent which has high oil adsorbability, can be easily recovered when sprayed onto the water surface, and has a small environmental load at the time of discarding.SOLUTION: An oil adsorbent 1 comprises a granular adsorbent substrate 2 made of an organic porous body, and a water repellent material 3 coated and/or impregnated with the adsorbent substrate and giving lipophilicity and water repellency to the adsorbent substrate 2. When the adsorbent substrate 2 including the water repellent material 3 and water are mixed and shaken for two hours, and then allowed to stand for 20 minutes, the ratio (w/w) of the adsorbent substrate including the water repellent material, floating on the water surface, is 90% or more.SELECTED DRAWING: Figure 1
