Application of cellulose membranes in ship oily wastewater separation systems
The transportation of ships generates a significant amount of oily wastewater,making the treatment of such waste crucial.Cellulose membranes,characterized by their porous structure,hydrophilicity,and hydrophobicity,are a com-mon method for oil-water separation.This paper proposes a ship oily wastewater separation system based on cellulose mem-brane technology,analyzes the principle of oil-water separation by cellulose membranes and common modification methods,and studies the preparation method of a modified carboxymethyl cellulose membrane.The performance of the prepared mod-ified cellulose membrane is also analyzed.The ship oily wastewater separation system proposed in this paper has good oil-water separation efficiency and high membrane flux,and it has a certain value for application.
