I would probably try a demulsifier, then skim off the oil. If
you are successful in getting the oil content down lower than 15
ppm in the water fraction, then you can pour it down the drain.
It is not so much the oil that is a problem as it will
biodegrade. But the metals content is the problem. Other than
paying someone to take it, there really isn't much you can do.
