[0002] In industrial production, a large amount of sulfuric acid is consumed in the processes of non-ferrous smelting, phosphoric acid industry, and rare earth roasting. Rare earth concentrates contain heavy metals such as lead, zinc, copper, arsenic, iron, fluorine, and manganese. The roasting flue gas purification system will produce waste acid containing sulfuric acid and fluoride. The output is large, the acid is highly corrosive, and the toxicity is high. Direct discharge will cause great environmental pollution to the receiving water body. Waste acid water treatment refers to the effective separation of soluble substances in dilute acid solution. The waste acid water can be recycled after treatment.

[0003] An adsorption device is used to adsorb fluorine-containing waste acid and heavy metals in ascites. However, in commonly used adsorption devices, when the adsorbent contacts the wastewater, the wastewater is stationary inside the device and the adsorbent is also fixedly stored inside the device. Therefore, a device for adsorbing fluorine-containing waste acid and heavy metals is proposed. Utility Model Content
