9. A mine water suspended matter treatment method is characterized in that the mine water suspended matter treatment device of any one of claims 1 to 7 is adopted, and comprises the following steps:
step S01, connecting the clear water pumping pipe with a negative pressure pump, so that the chambers in the inner cylinder body and the outer cylinder body are both in negative pressure, and pumping the mine muddy water into the outer cylinder body through the water inlet pipe; separating the mine mud water through a cyclone separation cavity;
step S02, the separated mine mud water enters the separate cavity, and the mine mud water enters the inner cylinder after being filtered by the filter ball component in the separate cavity;
and step S03, the mine muddy water enters the upper cover after being filtered by the membrane module and is finally pumped away by the clear water pumping pipe.
