Polishing solution purification treatment system

The utility model relates to the field of polishing solution treatment, and provides a polishing solution purification treatment system. Comprising a plurality of polishing machine tables, water return tanks arranged corresponding to the polishing machine tables, a transfer water tank communicated with the water return tanks, a waste water collecting tank communicated with the transfer water tank, a first water pump for pumping polishing liquid in the transfer water tank into the waste water collecting tank, a filter tank communicated with the waste water collecting tank and a centrifugal machine communicated with the filter tank. The second water pump is used for pumping the polishing solution in the wastewater collecting box and the filtering box into the centrifugal machine. Through the arrangement of the technical scheme, the polishing solution adopts a centrifugal filtration mode and a side filtration mode, so that impurities such as fluff in the polishing solution in the machining process can be effecti
