The exploitation, transportation, and utilization of various oil products frequently generate substantial volumes of oily wastewater, making the development of efficient treatment methods imperative for addressing environmental pollution and water scarcity. In this study, sodium hypochlorite was first employed to oxidize and etch the surface of the nylon mesh separation membrane (NFM), resulting in a modified NFM (M-NFM) characterized by a unique honeycomb-like porous structure and an abundance of oxygen-containing functional groups. Subsequent...
