Detailed Implementation

[0022] Example 1:

[0023] like Figure 1 As shown, a wastewater defluorination reaction device includes an inlet main pipe 1, with a wastewater source connected to the front end of the inlet main pipe 1. Multiple inlet branch pipes 2 are connected to the right side of the inlet main pipe 1, and a treatment channel 3 is connected to the right end of the multiple inlet branch pipes 2. An insertion port 31 is provided at the top of the treatment channel 3, and an adsorption chamber 4 is inserted into the insertion port 31. Drainage branch pipes 5 are connected to the right end of the multiple treatment channels 3, and the lower ends of the multiple drainage branch pipes 5 are all connected to a drainage main pipe 6.

[0024] like Figure 2 , Figure 3 As shown, the adsorption chamber 4 includes an adsorption net 41, which is filled with an adsorbent 42. A sealing plate 43 is provided above the adsorption net 41. The sealing plate 43 is connected to the top outer wall of the processing channel 3 by screws 44. Two snap-fit ​​grooves 45 are fixedly connected to the lower surface of the sealing plate 43. Two snap-fit ​​plates 46 are provided on the top of the adsorption net 41, and the two snap-fit ​​plates 46 are snapped into the two snap-fit ​​grooves 45 respectively.

[0025] This structure facilitates the replacement of the adsorbent 42 within the adsorption mesh 41, and the adsorbent is a commercially available product.

[0026] Example 2:

[0027] The difference between this embodiment and embodiment 1 is that in this embodiment, each of the multiple inlet branch pipes 2 is equipped with a control valve 21, and each of the multiple drain branch pipes 5 is equipped with a water suction pump 51.

[0028] Compared to Example 1, in this embodiment, when replacing the adsorbent 42, the control valve 21 on the inlet branch pipe 2 is closed before replacement, so as not to affect the efficiency of other treatment channels 3 in treating sewage normally.

[0029] Example 3:

[0030] The difference between this embodiment and embodiment 2 is that, in this embodiment, as Figure 4As shown, an ultrasonic oscillator 7 is fixedly connected to the bottom of each of the multiple processing channels 3, and a support plate 8 is fixedly connected to the outer wall of the multiple ultrasonic oscillators 7 and the multiple processing channels 3. A fixed base 9 is fixedly connected to the bottom of the support plate 8.

[0031] Compared to Example 2, this embodiment uses ultrasonic oscillator 7 to generate ultrasonic oscillation, which is beneficial to promoting the adsorption efficiency of adsorbent 42 for fluoride ions.

[0032] Example 4:

[0033] The difference between this embodiment and embodiment 3 is that a sealing ring 47 is provided between the sealing plate 43 and the top outer wall of the processing channel 3 in this embodiment.

[0034] Compared with Example 3, in this embodiment, the sealing ring 47 can effectively improve the sealing between the adsorption chamber 4 and the processing channel 3, and prevent water seepage and leakage.

[0035] The working method of Embodiment 4 above includes the following steps:

[0036] S1. Wastewater enters from the main inlet pipe 1 and enters the treatment channel 3 through the branch inlet pipe 2. The filter chamber 4 is inserted into the treatment channel 3 through the insertion port 31. The adsorbent 42 in the filter chamber 4 adsorbs fluoride ions in the wastewater. The ultrasonic oscillator 7 generates ultrasonic vibration to improve the adsorption efficiency of the adsorbent 42 in adsorbing fluoride ions. The water after adsorption treatment is discharged into the main drain pipe 6 through the branch drain pipe 5. The water pump 51 provides power for the water flow and at the same time prevents the water in the main drain pipe 6 from flowing back into the treatment channel 3.

[0037] S2. When replacing the adsorbent 42, close the control valve 21 and the water pump 51, unscrew the screw 44, remove the adsorption chamber 4, and then use the sliding snap-fit ​​plate 46 to separate the adsorption net 41 from the sealing plate 43. After replacing the adsorbent 42, use the snap-fit ​​plate 46 to snap into the snap-fit ​​groove 45 to snap the adsorption net 41 into the sealing plate 43. Then insert the adsorption chamber 4 through the insertion port 31 and tighten the screw 44.

[0038] In the above embodiments, the ultrasonic oscillator 7, control valve 21, and water pump 51 are all commercially available products. As long as they can achieve the function of this utility model, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.
