Copper wire drawing oil wastewater
Wire drawing oil is mainly used in the metal (such as copper, aluminum) wire drawing process of the wire and cable industry, playing roles in lubrication, cooling, cleaning, etc. As the working time of the wire drawing fluid increases, free acids and alkalis in the wire drawing fluid gradually accumulate, which reduces the lubricating capacity of the wire drawing fluid. In severe cases, this will cause wire breakage. At this point, the wire drawing fluid needs to be replaced, and wire drawing oil wastewater is generated accordingly.
The treatment process of copper wire drawing fluid waste mainly consists of demulsification, oil-water separation, oil removal, copper removal, adjustment, and oil-water combination.
