| description | The utility model discloses pretreatment equipment for oil stains and SS in grinding wastewater. The device comprises a stirring chamber, a gas dissolving chamber, a cyclone separator and a separationchamber, a grinding wastewater inlet is formed in the stirring chamber, the stirring chamber and the gas dissolving chamber are both communicated with the cyclone separator, an SS outlet is formed inthe bottom of the cyclone separator, the top of the cyclone separator is communicated with the separation chamber, an oil phase outlet is formed in the upper portion of the separation chamber, and awater phase outlet is formed in the lower portion of the separation chamber. The device is compact in structure and small in occupied area, demulsification, SS separation and oil-water separation canbe completed at the same time, the SS removal rate of grinding wastewater is larger than 90%, the oil stain removal rate reaches 70%, the effect is extremely good, and the operation cost is low.
