The invention discloses a mill tailing water treatment method. The method comprises the steps that (1), mill tailing water is pumped into a reaction groove (3) through a mill tailing water return pump (1), solid carbon dioxide in a carbon dioxide storage tank (2) is gasified and then fed into the reaction groove (3), reaction achieved through stirring is carried out for a certain period of time, and a reaction conveying pump (4) is used for conveying a reactant to a mill tailing water treater (5); (2), mill tailing water obtained after the reaction is fed into the mill tailing water treater (5) to be separated, suspended matter and solids generated after the reaction are separated in the mill tailing water treater (5), after separation is carried out by a treater film, clear water overflows from the upper portion of the mill tailing water treater (5) to a water collection groove, and then the clear water is pumped to a production system to be used. When the mill tailing water treatment method is adopted for t
