[0026] When used specifically, fluorine-containing wastewater is added into the rectangular tube 702, and a chemical agent that promotes the formation of fluorine ion precipitation is quantitatively added into the fixed box 1001, and then the motor 2 703 and the motor 3 901 are started, the motor 3 901 drives the rotating rod 903 to rotate, the rotating rod 903 drives the clamping ring 1 904 to rotate, the clamping ring 1 904 drives the clamping ring 2 905 to rotate through the transmission belt, the clamping ring 2 905 drives the screw rod 802 to rotate, and the screw rod 802 drives the pressure plate 804 to rotate along the limit block 80 3 moves forward, so that the pressure plate 804 squeezes the chemical agent into the pressure nozzle 705, and evenly injects it into the fluorine-containing wastewater through the pressure nozzle 705. At the same time, the motor 2 703 drives the stirring paddle 704 to rotate, and the stirring paddle 704 further mixes the chemical agent and the fluorine-containing wastewater evenly. The fluorine ions in the fluorine-containing wastewater react with the chemical agent to produce a fluorine-containing precipitate. After the stirring paddle 704 stirs for a certain period of time, the motor 2 703 is turned off to stop the stirring of the stirring paddle 704, and the fluorine-containing precipitate is The wastewater is freely dropped and precipitated onto the lower partition 1102, and then the liquid transfer valve 706 is opened to allow the wastewater with fluoride ions that may not be completely treated to flow into the hollow column 501 below through the liquid transfer valve 706.

After the adsorption is completed, the liquid outlet valve 503 can be opened to discharge the treated wastewater.

[0027] When a large amount of fluorine-containing precipitates accumulates, the precipitates can be processed after the fluorine-containing wastewater has completed the precipitation treatment and flows into the hollow column 501 below through the liquid transfer valve 706. It is only necessary to start the electric telescopic rod 1003, and the electric telescopic rod 1003 drives the connecting block 1004 to move forward. The connecting block 1004 drives the upper partition 1005 and the upper rack 1006 to move forward together. The upper rack 1006 drives the columnar gear 1101 to rotate, and the columnar gear 1101 drives the lower partition 1102 to move backward through the lower rack 1103. After the lower partition 1102 moves backward, the precipitates can flow into the trapezoidal box 701 below from the gap between the two lower partitions 1102. After the precipitate treatment is completed, the electric telescopic rod 1003 is reset, and the upper partition 1005 and the lower partition 1102 can be reset.
