[0041] Referring to Figure 1The inlet end of the medicament delivery pipeline 3 is connected with an enzyme storage tank 24, and a variable frequency delivery pump 25 is installed on the outer wall of the medicament delivery pipeline 3. The inlet end of the variable frequency delivery pump 25 is connected with the liquid outlet of the enzyme storage tank 24. The oxidation-reduction agent (enzyme) is stored in the enzyme storage tank 24. The variable frequency delivery pump 25 is started to suck the oxidation-reduction agent from the enzyme storage tank 24. The oxidation-reduction agent in the medicament delivery pipeline 3 is sprayed into the reaction box 1 through the medicament spray head 4, so as to facilitate the provision of the oxidation-reduction agent to the reaction box 1.

[0042] With reference to Figure 2 A drainage plate 10 is fixed on the inner wall of the reaction box 1 by screws. An impurity filter box 9 is fixed on the side wall of the drainage plate 10 by screws. A fixed hole is formed in the side wall of the reaction box 1.

[0045] Embodiment two

[0046] Example 2 differs from Example 1 in that: (Refer to...) Figure 3 and Figure 4 A guide rail 12 is fixed to the inner wall of the reaction chamber 1 by bolts. The guide rail 12 is set along the height direction of the reaction chamber 1. A sliding box 27 is slidably connected to the guide rail 12. A sliding block 14 is slidably connected to the slide rail 13. A through hole is opened through the side wall of the sliding block 14. A rotating shaft 15 is rotatably connected to the sliding block 14. The rotating shaft 15 passes through the through hole. A drive assembly 17 is provided on the slide rail 13 to drive the rotating shaft 15 to rotate. The rotating shaft 15 is driven to rotate under the drive assembly 17.

[0047] Reference Figure 4 The end of the rotating shaft 15 is coaxially fixed with a mounting shell 16. The nozzle assembly 5 near the defoaming nozzle 8 is mounted on the mounting shell 16. With the support of the mounting shell 16, the two nozzle assemblies 5 are arranged vertically to facilitate the spraying of oxidizing and reducing agent into the reaction chamber 1. When a large number of bubbles are generated in the reaction chamber 1, the drive assembly 17 is activated. The drive assembly 17 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the mounting shell 16 to rotate, so that the nozzle assembly 5 on the mounting shell 16 is set upward. At this time, not only can the oxidizing and reducing agent be sprayed into the reaction chamber 1 through the liquid spray nozzle 4, but the liquid spray nozzle 4 can also help eliminate the bubbles in the reaction chamber 1.

[0048] Reference Figure 4 A branch pipe 28 is connected to the side wall of the liquid delivery pipeline 3. One end of the branch pipe 28 is connected to the liquid delivery pipeline 3 through a swivel joint, and the other end of the branch pipe 28 is connected to the mounting shell 16 through a swivel joint. The rotating structure at both ends of the branch pipe 28 makes the rotation of the mounting shell 16 smoother and prevents the branch pipe 28 from getting tangled during the rotation of the mounting shell 16.

[0049] Reference Figure 4 The drive assembly 17 includes a rack 172 fixed to the side wall of the slide rail 13 by screws and a gear 171 coaxially fixed to the rotating shaft 15. The gear 171 can mesh with the rack 172. The inner wall of the sliding box 27 is provided with a drive member 18 for driving the sliding block 14 to slide. In this application, the drive member 18 is preferably a drive cylinder. The piston rod of the drive member 18 is fixedly connected to the side wall of the sliding block 14 by a connecting rod. When the drive member 18 is started, the piston rod of the drive member 18 slides, thereby driving the sliding block 14 to slide.

[0050] Reference Figure 4A drive block 19 is fixed to the side wall of the sliding block 14 by screws. In this application, the drive block 19 is preferably wedge-shaped. A receiving block 20 is fixed to the inner wall of the reaction chamber 1 by screws. The receiving block 20 is wedge-shaped. The drive member 18 drives the sliding block 14 to slide. The sliding block 14 drives the drive block 19 to move. The side wall of the drive block 19 abuts against the side wall of the receiving block 20. With the support of the receiving block 20, the drive block 19 moves along the height direction of the reaction chamber 1, so that the sliding box 27 slides along the guide rail 12. The mounting shell 16 is lifted, and the nozzle group 5 near the defoaming nozzle 8 is lifted, so that the oxidizing and reducing agent can be sprayed into the bubbles formed in the upper part of the reaction chamber 1 through the nozzle group 5, thereby eliminating the bubbles.

[0051] In Embodiment 2 of this application, the implementation principle of a safety device for treating hydrogen peroxide wastewater is as follows: The variable frequency delivery pump 25 is started, drawing the oxidizing agent from the enzyme storage tank 24 and spraying it into the reaction tank 1 through the liquid spray nozzle 4. When a large number of bubbles are generated in the reaction tank 1, on the one hand, the circulating water submersible pump 6 is started, and some of the water generated in the reaction tank 1 enters the defoaming nozzle 8, eliminating the bubbles through the defoaming nozzle 8; on the other hand, the drive component 18 is started, and the piston rod of the drive component 18 slides, causing the sliding block 14 to slide. The gear 171 meshes with the rack 172, driving the rotating shaft 15 to rotate. The rotating shaft 15 drives the mounting shell 16 to rotate, and the drive block 19 abuts against the receiving block 20, causing the mounting shell 16 to move towards the defoaming nozzle 8. The mounting shell 16 is lifted, and the nozzle assembly 5 eliminates the bubbles through the oxidizing agent, making the bubble elimination more efficient. After the air bubbles are eliminated, the drive unit 18 drives the mounting housing 16 to rotate, so that the nozzle assembly 5 on the mounting housing 16 is set downward.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
