摘要： A method for deep removal of divalent and trivalent scaling ions from heavy oil produced water is described. The method comprises performing divalent and trivalent scaling ion deep removal treatment on heavy oil produced water by using a macroporous weak acid resin, to reduce divalent and trivalent scaling ions in the heavy oil produced water to 50 μg/L. The water quality of produced water treated using the method is superior to the boiler water standard, a silicon removal process in a conventional heavy oil produced water treatment process can be cancelled, and significant economic benefits are achieved.
