[0029] In the present embodiment, with the development of industry, the amount of industrial wastewater is also greatly increasing, so the demand for sewage treatment is also increasing. Photocatalyst technology is a method for treating sewage by photocatalytic oxidation technology. In the sewage treatment process, photocatalyst needs to be catalyzed by ultraviolet light. However, in the sewage treatment process, the sediments in the sewage may adhere to the surface of the first light emitting unit 21 or the first reaction unit 22, thereby affecting the quality of sewage treatment. The present embodiment provides a sewage treatment device, such as Figure 1As shown, the sewage treatment device comprises a shell assembly 01. A first reaction assembly 02, which can comprise a first light emitting unit 21, a first reaction unit 22, and a first turbulence unit 23. The first light emitting unit 21 is detachably connected with the shell assembly 01. The first light emitting unit 21 can be arranged in the hollow cavity of the shell assembly 01, and the relative position of the first light emitting unit 21 and the shell unit is fixed. The first reaction unit 22 is detachably connected with the shell assembly 01. The first turbulence unit 23 is detachably connected with the shell assembly 01. The space enclosed by the first side wall of the first reaction unit 22 along the first direction and part of the shell assembly 01 can be a first chamber, and sewage can enter the first chamber from the water inlet 12. The space enclosed by the second side wall of the first reaction unit 22 along the first direction and part of the shell assembly 01 can be a third chamber, which can be in communication with the water outlet 13, so that the treated sewage can flow out from the water outlet 13. The space enclosed by the two side walls of the first reaction unit 22 and part of the shell assembly 01 can be a second chamber, which can purify the sewage. The first chamber can be in communication with the second chamber through the first side wall of the first reaction unit 22 along the first direction, so that the sewage can enter the second chamber through the first chamber. The second chamber can be in communication with the third chamber through the second side wall of the first reaction unit 22 along the first direction. The first light emitting unit 21 can be arranged in the second chamber, so as to provide light energy for the first reaction unit 22 through the first light emitting unit 21. The first turbulence unit 23 can be arranged in the second chamber, so that the first turbulence unit 23 can deliver airflow to the first light emitting unit 21 and the first reaction unit 22.

[0030] The sewage treatment device can comprise a treatment state. The treatment state can comprise that the first light emitting unit 21 emits ultraviolet light to the first reaction unit 22, and provides light source for the first reaction unit 22 through the ultraviolet light, so that the first reaction unit 22 can generate active oxidants, thereby achieving the purpose of sewage treatment. The first turbulence unit 23 delivers airflow to the first light emitting unit 21 and the first reaction unit 22 respectively, removes the deposits on the surfaces of the first light emitting unit 21 and the first reaction unit 22 through the airflow delivered by the first turbulence unit 23, and also can stir the sewage, thereby improving the effect of sewage treatment. The ultraviolet light emitted by the first light emitting unit 21 and the substances generated by the first reaction unit 22 can be located in the hollow cavity of the shell assembly 01, and through contact with the sewage, the toxic substances in the sewage can be oxidized and decomposed into harmless substances. The sewage can pass through the first chamber, the second chamber, and the third chamber in sequence.

[0031] In the embodiment, the shell assembly 01 can comprise a shell 11, a water inlet 12, and a water outlet 13. The water inlet 12 and the water outlet 13 are detachably connected with the shell 11, respectively, as shown in the figure. Figure 2As shown, a valve 14 can be installed at the water inlet 12. The space enclosed by the partial shell 11 on the first side of the first reaction unit 22 in the first direction can be a first chamber. The space enclosed by the partial shell 11 on the first reaction unit 22 can be a second chamber, which can purify the sewage. The space enclosed by the partial shell 11 on the second side of the first reaction unit 22 in the first direction can be a third chamber. The water inlet 12 can be in communication with the first chamber, so that the sewage can enter the first chamber from the water inlet 12. The water outlet 13 can be in communication with the third chamber, so that the treated sewage can flow out of the water outlet 13. The water inlet 12 can be lower than the water outlet 13, so that the sewage can stay in the sewage treatment device for a longer time when passing through the sewage treatment device, so that the toxic substances in the sewage can contact the oxidant in the sewage treatment device for a longer time, and the sewage treatment effect is better. The first light emitting unit 21, the first reaction unit 22, and the first turbulence unit 23 are respectively detachably connected with the shell 11. The first light emitting unit 21, the first reaction unit 22, and the first turbulence unit 23 can be respectively arranged in the hollow cavity of the shell 11, so as to fix the relative positions of the first light emitting unit 21, the first reaction unit 22, and the first turbulence unit 23, so that they can cooperate with each other during the reaction process, so as to achieve the purpose of sewage treatment. In other embodiments, the first light emitting unit 21 can include a first light emitting part 211 and a first waterproof pipe 212. The first light emitting part 211 and the first waterproof pipe 212 can be arranged in the second chamber, and the first waterproof pipe 212 can be sleeved on the surface of the first light emitting part 211 to prevent the first light emitting part 211 from directly contacting the sewage.

[0032] The processing state can also include the sewage entering the first chamber from the water inlet 12. The sewage can enter the water outlet 13 from the third chamber. The ultraviolet light emitted by the first light emitting unit 21 and the substance generated by the first reaction unit 22 can be located in the hollow cavity of the shell 11, so that the sewage in the hollow cavity of the shell 11 can react with the ultraviolet light emitted by the first light emitting unit 21 and the substance generated by the first reaction unit 22, thereby achieving the purpose of sewage treatment.

[0033] In the embodiment, the first reaction unit 22 can include a first photocatalyst 221 and a second photocatalyst 222. The first photocatalyst 221 and the second photocatalyst 222 are detachably connected to the shell 11. The first photocatalyst 221 can be arranged on the side of the first light emitting unit 21 close to the water inlet 12. The second photocatalyst 222 can be arranged on the side of the first light emitting unit 21 close to the water outlet 13. Thus, the sewage can sequentially contact the first photocatalyst 221 and the second photocatalyst 222 during the flow of the sewage through the sewage treatment device, thereby improving the sewage treatment effect. The space surrounded by the first photocatalyst 221 and part of the shell 11 can be a first chamber. The space surrounded by the first photocatalyst 221, the second photocatalyst 222, and part of the shell 11 can be a second chamber. The space surrounded by the second photocatalyst 222 and part of the shell 11 can be a third chamber.

[0034] The flow rate of the sewage through the first photocatalyst 221 close to the bottom end of the shell 11 can be a first flow rate. The flow rate of the sewage through the first photocatalyst 221 close to the top end of the shell 11 can be a second flow rate. The flow rate of the sewage through the second photocatalyst 222 close to the bottom end of the shell 11 can be a third flow rate. The flow rate of the sewage through the second photocatalyst 222 close to the top end of the shell 11 can be a fourth flow rate. The first flow rate can be less than the second flow rate, so that the sewage can enter the second chamber in large quantities from the first photocatalyst 221 close to the bottom end of the shell 11. The third flow rate can be greater than the fourth flow rate, so that the sewage can enter the third chamber in large quantities from the second photocatalyst 222 close to the top end of the shell 11, and the combination of the two makes the sewage stay in the second chamber for a longer time, i.e., the contact with the first photocatalyst 221 and the second photocatalyst 222 is more sufficient, thereby improving the sewage treatment effect.

[0035] In the embodiment, the first disturbance unit 23 can include a first disturbance part 231. The first disturbance part 231 is detachably connected to the shell 11. The first disturbance part 231 can be arranged in the second chamber. The first disturbance part 231 can be arranged at the bottom end of the hollow cavity of the shell 11. The first disturbance part 231 can output air flow into the second chamber, which can remove the deposits on the surfaces of the first light emitting unit 21, the first photocatalyst 221, and the second photocatalyst 222 through the air flow, and can also stir the sewage to prevent the deposits in the sewage from depositing on the surfaces of the first light emitting unit 21, the first photocatalyst 221, and the second photocatalyst 222, thereby improving the sewage treatment effect.

[0036] In the embodiment, the first turbulence unit 23 can further include a second turbulence part 232. The second turbulence part 232 is detachably connected with the shell 11. The second turbulence part 232 can be arranged on the side of the first reaction unit 22 away from the first turbulence part 231, so that the bubbles generated by the first turbulence part 231 can be broken when contacting the second turbulence part 232, further agitating the sewage, preventing the deposition of sediments in the sewage on the surface of the first light-emitting unit 21 and the first photocatalyst 221 and the second photocatalyst 222.

[0037] In the embodiment, the sewage treatment device can further include a second reaction assembly 03. The second reaction assembly 03 can be arranged in the third cavity. The second reaction assembly 03 can be arranged spaced apart from the first reaction assembly 02. When the sewage passes through the second reaction assembly 03, the second reaction assembly 03 can further treat the sewage, thereby improving the treatment effect of the sewage. The second reaction assembly 03 can include a second light-emitting unit 31, a second reaction unit 32, and a second turbulence unit 33. The second light-emitting unit 31, the second reaction unit 32, and the second turbulence unit 33 are detachably connected with the shell 11, and the relative positions of the three are fixed by the shell 11, so that the three can cooperate with each other to achieve the purpose of treating the sewage. The third cavity can include a first area, a second area, and a third area. The space surrounded by the second reaction assembly 03 along the side close to the water inlet 12, the first reaction assembly 02 close to the water outlet 13, and part of the shell 11 can be the first area, and the sewage can enter the first area from the second cavity. The space surrounded by the two side walls of the second reaction assembly 03 and part of the shell 11 can be the second area. The space surrounded by the second reaction assembly 03 close to the water outlet 13 and part of the shell 11 can be the third area. The second cavity can be in communication with the first area through the first reaction unit 22 close to the water outlet 13. The first area can be in communication with the second area through the first side wall of the second reaction unit 32 close to the water inlet 12 in the first direction. The second area can be in communication with the third area through the second reaction unit 32 close to the water outlet 13. The sewage flows in the direction from the first area to the third area, so that the sewage can pass through the second reaction assembly 03 during the flow, thereby further treating the sewage and improving the treatment effect of the sewage. The second light-emitting unit 31 can be arranged in the second area, and the second turbulence unit 33 can be arranged in the second area, so that the second light-emitting part 311 can provide light sources for the two side walls of the second reaction assembly 03 at the same time. In other embodiments, the second light-emitting unit 31 can further include a second waterproof pipe 312 to prevent the second light-emitting part 311 from being directly exposed to the sewage.

[0038] The treatment state can further include that the sewage sequentially passes through the first area, the second area, and the third area.

[0039] In the embodiment, the second reaction unit 32 can include a third photocatalyst 321 and a fourth photocatalyst 322. The third photocatalyst 321 and the fourth photocatalyst 322 are detachably connected with the shell 11, so as to fix the relative positions of the third photocatalyst 321 and the fourth photocatalyst 322. The third photocatalyst 321 can be arranged on the side of the second light-emitting unit 31 close to the water inlet 12. The fourth photocatalyst 322 can be arranged on the side of the second light-emitting unit 31 close to the water outlet 13, so that the sewage can pass through the third photocatalyst 321 and the fourth photocatalyst 322 in sequence. The space surrounded by the third photocatalyst 321, the first reaction assembly 02 and part of the shell 11 can be a first region. The space surrounded by the third photocatalyst 321, the fourth photocatalyst 322 and part of the shell 11 can be a second region. The space surrounded by the fourth photocatalyst 322 and part of the shell 11 can be a third region. The flow rate of the sewage passing through the third photocatalyst 321 close to the bottom end of the shell 11 can be a fifth flow rate. The flow rate of the sewage passing through the third photocatalyst 321 close to the top end of the shell 11 can be a sixth flow rate. The flow rate of the sewage passing through the fourth photocatalyst 322 can be a seventh flow rate. The flow rates of the sewage passing through the third photocatalyst 321 are the same, so that the sewage flowing into the third region from the third photocatalyst 321 can uniformly pass through the fourth photocatalyst 322, preventing the sewage from directly flowing out of the water outlet 13 and staying in the third region for too short a time, thereby affecting the sewage treatment quality. At the same time, the reaction between the sewage and the substances generated by the photocatalyst can generate tiny precipitates, and these precipitates can block the path for the sewage to pass through the third photocatalyst 321. Therefore, the seventh flow rate can be slightly larger, that is, the aperture of the fourth photocatalyst 322 is slightly increased, to prevent the fourth photocatalyst 322 from being blocked. The fifth flow rate can be greater than the sixth flow rate, so that the sewage stays in the second region for a longer time, improving the sewage treatment effect of the second region. The seventh flow rate can be less than the fifth flow rate and greater than the sixth flow rate, so that the total flow rates of the third photocatalyst 321 and the fourth photocatalyst 322 are similar, preventing the pressure of the sewage in the second region from being too large or too small. In other embodiments, the shell assembly 01 can further include a first recess 15 and a second recess 16. The first recess 15 can be arranged in the second region and fixedly connected with the bottom end of the shell 11. The second recess 16 can be arranged in the third region and fixedly connected with the bottom end of the shell 11. When the sewage flows through the second region, the deposits in the sewage can be deposited in the first recess 15. When the sewage passes through the third region, the deposits in the sewage can be deposited in the second recess 16, further improving the sewage treatment effect.

[0040] In the embodiment, the second disturbance unit 33 can include a third disturbance part 331. The third disturbance part 331 is detachably connected with the shell 11. The third disturbance part 331 is arranged in the second region. The third disturbance part 331 can be arranged in the second region.

[0041] The processing state can include the third flow disturbing part 331 conveying the air flow towards the bottom end of the shell 11, so that the air flow can first move towards the direction close to the bottom end of the shell 11, and then move towards the direction close to the top end of the shell 11 under the action of the buoyancy, increasing the moving path of the air flow in the second area and improving the flow disturbing effect of the air flow. The air flow can remove the deposits on the surfaces of the second light emitting part 311, the third photocatalyst 321 and the fourth photocatalyst 322, and can also stir the sewage to prevent the deposits in the sewage from depositing on the surfaces of the second light emitting unit 31, the third photocatalyst 321 and the fourth photocatalyst 322, thereby improving the sewage treatment effect.

[0042] In the embodiment, the second flow disturbing unit 33 further includes a fourth flow disturbing part 332. The fourth flow disturbing part 332 is arranged on the side of the second reaction unit 32 away from the bottom end of the shell 11, so that the bubbles generated by the third flow disturbing part 331 can be broken when contacting the fourth flow disturbing part 332, further stirring the sewage and preventing the deposits in the sewage from depositing on the surfaces of the second light emitting unit 31, the third photocatalyst 321 and the fourth photocatalyst 322.

[0043] In the embodiment, the sewage treatment device can further include a first heating assembly 04. The first heating assembly 04 is detachably connected with the shell 11. The first heating assembly 04 can be arranged in the first area. By arranging the first heating assembly 04 to heat the sewage, the reaction speed of the toxic substances in the sewage and the substances generated by the photocatalyst can be increased, the decomposition of the toxic substances in the sewage is promoted, and the sewage treatment effect is improved.

[0044] In the embodiment, the sewage treatment device can further include a second heating assembly 05. The second heating assembly 05 is detachably connected with the shell assembly 01. The second heating assembly 05 can be arranged in the first chamber. By arranging the first heating assembly 04 to heat the sewage, the reaction speed of the toxic substances in the sewage and the substances generated by the photocatalyst can be increased, the decomposition of the toxic substances in the sewage is promoted, and the sewage treatment effect is improved. At the same time, the increase of the temperature can also expand the volume of the air in the air flow generated by the third flow disturbing, i.e. the volume of the generated bubbles is increased, further improving the flow disturbing effect of the third flow disturbing part 331.

[0045] Those skilled in the art can understand that the above embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and details without departing from the scope of the present disclosure.
