[0006] As a further improvement of the present application, parallel light plates and curtains are fixedly connected to both sides of the top of the processing box, and the parallel light plates and curtains are respectively located on both sides of the multiple gas collecting hoods.

[0007] As a further improvement of the present application, a sewage collection area is provided in the treatment box located on one side of the ultrasonic dechlorination station close to the water outlet pipe. A sewage pump is fixedly connected to the top of the central treatment box. The two ends of the sewage pump are respectively connected to the sewage collection area and the central treatment box. A wastewater pipe is fixedly connected to the bottom of the central treatment box.

[0008] As a further improvement of the present application, the side walls of the plurality of gas collecting hoods are fixedly connected with blow pipes, and one end of the plurality of blow pipes is fixedly connected with a supplementary pipe.

[0009] As another improvement of the present application, a chlorine gas supply machine is provided on one side of the treatment box, and one end of the replenishment pipe extends to the outside of the treatment box and is fixedly connected to the chlorine gas supply machine.

[0010] As another improved supplement of the present application, a heating rod and a liquid level sensor are fixedly connected to the inner wall of the processing box.

[0011] As another improved supplement of the present application, a leak-proof cover is provided on the top of the processing box, and the leak-proof cover is located on the upper side of multiple capillary tubes. The side wall of the central processing box is fixedly connected to a vacuum pump, and both ends of the vacuum pump are respectively connected to the leak-proof cover and the central processing box.

[0012] A first method for using a tap water dechlorination device for preparing experimental hatching water comprises the following steps: S1. Open the water inlet pipe and the water outlet pipe. The tap water enters the treatment box through the water inlet pipe and is discharged through the water outlet pipe after passing through the ultrasonic dechlorination station. At the same time, the liquid level of the tap water is controlled to be flush with the top surface of the working area. The flow of the tap water moves from the left side to the right side of the working area. The flow rate of the tap water is controlled by the flow control valve to increase or decrease the retention time of the tap water in the working area. S2, start the ultrasonic dechlorination table to vibrate the tap water, so that the chlorine in the tap water is discharged outward, and the chlorine enters the gas collecting hood and the inside of the capillary tube to make the light ball float; S3, start the micro air pump to extract chlorine gas from multiple gas collecting hoods through the main connecting pipe and the extraction pipe, and discharge it into the central processing box. When chlorine gas continues to enter the gas collecting hood and the extraction speed is greater than the extraction speed of the micro air pump, the light ball floats. When the amount of chlorine gas entering the gas collecting hood is low or no chlorine gas enters and the extraction speed is less than the extraction speed of the micro air pump, the light ball falls. S4. By observing the height of multiple indicator rods, the chlorine content in tap water at different positions can be determined. When the tap water is retained in the working area for too long, the internal chlorine is completely discharged before the tap water flows to the outlet pipe. At this time, the multiple indicator rods are as follows: the indicator rod on the left rises and the indicator rod on the right falls. When the tap water is retained in the working area for a short time, the internal chlorine is not completely discharged when the tap water is drawn out of the outlet pipe. At this time, the multiple indicator rods are as follows: all indicator rods rise. S5. According to the status of the multiple indicator rods, the flow rate of tap water is properly controlled through the flow control valve until 2-4 indicator rods on the right side drop.

[0013] A second method for using a tap water dechlorination device for preparing experimental hatching water comprises the following steps: A1. Close the ultrasonic dechlorination table and the water outlet pipe, open the water inlet pipe, fill the treatment box with tap water, and make the tap water level flush with the top surface of the work area, then close the water inlet pipe, start the chlorine supply machine to fill the gas hood and the capillary tube with chlorine through the supplementary pipe, at this time, all the indicator rods rise to the highest position, and close the chlorine supply machine; A2. Start the micro air pump to extract the chlorine inside the gas collecting hood through the main connecting pipe, and start the ultrasonic dechlorination table to vibrate the chlorine inside the tap water to float outward; A3. The chlorine emission pattern of tap water corresponding to the violent oscillation position of the ultrasonic dechlorination table is: fast but short duration, and the descending pattern of the indicator rod here is that it does not descend and then descends rapidly. The chlorine emission pattern of tap water corresponding to the gentle oscillation position of the ultrasonic dechlorination table is: slow but long duration, and the descending pattern of the indicator rod here is that it descends slowly; A4. According to the descending rules of the indicator rods at different positions, the working area of ​​the ultrasonic dechlorination station can be determined. When the working area of ​​the ultrasonic dechlorination station changes, it can be determined whether the ultrasonic dechlorination station is damaged. A5. After the tap water is shaken to remove chlorine, open the outlet pipe to discharge the treated tap water.

[0014] In summary, the first method of use of the present invention can continuously and uninterruptedly dechlorinate tap water, greatly improving the dechlorination efficiency of tap water. At the same time, it can make targeted adjustments to the processing time for tap water with different chlorine content, thereby ensuring the quality of dechlorination while further improving the dechlorination efficiency. Through the second method of use, the action area of ​​the ultrasonic dechlorination station can be detected, and based on the changes in the dechlorination efficiency of the action area, it can be determined whether the ultrasonic dechlorination station is damaged, so that the ultrasonic dechlorination station can be repaired more timely.
