If the specific posture changes, the directional indicator will also change accordingly.

[0023] See Figure 1-2 As shown, a dental wastewater treatment device includes an ozone generating and reducing mechanism 1 and a wastewater treatment cabinet 2. The wastewater treatment cabinet 2 contains a primary wastewater treatment chamber 21, a secondary wastewater treatment chamber 22, and a tertiary wastewater treatment chamber 23. The secondary wastewater treatment chamber 22 and the tertiary wastewater treatment chamber 23 are directly connected through a through-hole 221. The secondary wastewater treatment chamber 22 is also connected to the primary wastewater treatment chamber 21 through a corresponding pipe, and a pump 3 is connected in series in the corresponding pipe. A device for treating wastewater is also provided within the primary wastewater treatment chamber 21. The wastewater treatment chamber 22 is equipped with a grid 4 for intercepting particulate matter and suspended solids, and has an inlet 211 on it; the secondary wastewater treatment chamber 22 is equipped with an activated carbon adsorption filter 5 for removing organic pollutants (such as humus, pesticide residues, organic compounds in industrial wastewater, etc.) and heavy metal ions from the wastewater; the tertiary wastewater treatment chamber 23 is equipped with a drain 231, and a first electromagnetic on / off valve 6 is connected to the drain 231; the ozone generating and reducing mechanism 1 is located on one side of the wastewater treatment cabinet 2 and is connected to the tertiary wastewater treatment chamber 23 through a pipeline.

[0024] Furthermore, casters 7 are respectively provided on the lower end surfaces of the ozone generating and reducing mechanism 1 and the sewage treatment cabinet 2 to facilitate the movement of the ozone generating and reducing mechanism 1 and the sewage treatment cabinet 2.

[0025] Furthermore, the sewage treatment cabinet 2 is provided with a sight glass manhole 8, through which the primary sewage treatment chamber 21 can be observed, and the impurities intercepted on the grille 4 can be cleaned.

[0026] Furthermore, a water sensor 9 is installed inside the primary sewage treatment chamber 21. The water sensor 9 is located on the inner bottom surface of the primary sewage treatment chamber 21 and is used to monitor whether there is sewage in the primary sewage treatment chamber 21.

[0027] Furthermore, a water filter 10 is connected in series in the pipe connecting the pump 3 and the primary sewage treatment chamber 21, and the water filter 10 is used to filter fine particles in the sewage; and a second electromagnetic on / off valve 11 is connected in series in the pipe connecting the water filter 10 and the primary sewage treatment chamber 21.

[0028] Furthermore, a one-way valve 12 is connected in series in the pipe connecting the pump 3 and the secondary sewage treatment chamber 22 to prevent sewage backflow in the secondary sewage treatment chamber 22; and a third electromagnetic on / off valve 13 is provided at the through hole 221 to prevent sewage from flowing from the secondary sewage treatment chamber 22 into the tertiary sewage treatment chamber 23 during the sewage treatment process.

[0029] Furthermore, a liquid level sensor is installed inside the tertiary sewage treatment chamber 23 to monitor the liquid level inside the tertiary sewage treatment chamber 23; in this embodiment, the liquid level sensor includes a high liquid level switch 151 and a low liquid level switch 152; and a submersible agitator 14 is installed inside the tertiary sewage treatment chamber 23 to agitate the sewage inside the tertiary sewage treatment chamber 23.

[0030] Furthermore, the ozone generation and reduction mechanism 1 includes an ozone generator and an ozone destroyer. The ozone generator is connected to the lower end of the tertiary sewage treatment chamber 23 via a corresponding pipe, allowing ozone to be introduced into the sewage in the tertiary sewage treatment chamber 23. The strong oxidizing properties of ozone are used to deeply oxidize the sewage, decomposing organic matter and killing pollutants such as bacteria and viruses. The ozone destroyer is connected to the upper end of the tertiary sewage treatment chamber 23 via a corresponding pipe, allowing the ozone-containing exhaust gas discharged from the tertiary sewage treatment chamber 23 to be decomposed and reduced to oxygen before being safely released into the atmosphere, thus avoiding direct ozone emission that could harm the environment.

[0031] The working principle of this utility model is as follows:

[0032] In use, wastewater enters the primary wastewater treatment chamber 21 through the inlet 211, and then is pumped into the secondary wastewater treatment chamber 22 through the water filter 10 under the action of the pump 3. It then flows into the tertiary wastewater treatment chamber 23 through the through hole 221. Finally, the first electromagnetic on / off valve 6 is opened, allowing the treated wastewater to be discharged through the outlet 231, thus completing the treatment of oral medical wastewater.

[0033] During the process of sewage flowing through the primary sewage treatment chamber 21, the secondary sewage treatment chamber 22, and the tertiary sewage treatment chamber 23, the screen 4 installed in the primary sewage treatment chamber 21 intercepts large particulate matter (such as dental instrument debris, cotton balls, etc.) and suspended matter in the sewage, while the water filter 10 filters out fine particles in the sewage; the activated carbon adsorption filter 5 removes organic pollutants (such as humus, pesticide residues, organic compounds in industrial wastewater, etc.) and heavy metal ions from the sewage; and finally, in the tertiary sewage treatment chamber 23, the ozone generator supplies ozone to the sewage to disinfect it (kill bacteria, viruses, fungi, spores and other microorganisms) and remove odors.

[0034] Furthermore, during the wastewater treatment process, when the wastewater level in the tertiary wastewater treatment chamber 23 is higher than the high-level switch 151, the second electromagnetic shut-off valve 11 and the third electromagnetic shut-off valve 13 close, and the pump 3 stops operating. Simultaneously, the ozone generation and reduction mechanism 1 starts, the ozone generator supplies ozone to the wastewater, and the ozone destroyer decomposes the ozone-containing exhaust gas discharged from the tertiary wastewater treatment chamber 23, reducing the ozone to oxygen before safely releasing it into the atmosphere, thus preventing direct ozone emissions from harming the environment. Additionally, the submersible mixer 14 starts, stirring the wastewater in the tertiary wastewater treatment chamber 23 to ensure good flow within the chamber, promoting uniform mixing of ozone with various pollutants in the wastewater, allowing the ozone oxidation effect to be fully and thoroughly utilized, ensuring the stability and efficiency of the wastewater treatment process. This process also ensures that the wastewater undergoes tertiary treatment... After the water treatment chamber 23 has finished treating the wastewater, the first electromagnetic shut-off valve 6 opens to discharge the fully treated wastewater from the tertiary wastewater treatment chamber 23. When the wastewater level in the tertiary wastewater treatment chamber 23 is lower than the low level switch 152, the first electromagnetic shut-off valve 6 closes and the third electromagnetic shut-off valve 13 opens. When the water sensor 9 detects water in the primary wastewater treatment chamber 21, the second electromagnetic shut-off valve 11 and the pump 3 open to continue transporting wastewater to the secondary wastewater treatment chamber 22. It should be noted that during the process of transporting wastewater from the primary wastewater treatment chamber 21 to the secondary wastewater treatment chamber 2, when the water sensor 9 detects no wastewater in the primary wastewater treatment chamber 21, the second electromagnetic shut-off valve 11 closes and the pump 3 stops operating. When the water sensor 9 detects wastewater in the primary wastewater treatment chamber 21, the second electromagnetic shut-off valve 11 and the pump 3 reopen to continue transporting wastewater.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
