Description
Technical Field
[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment device. Background Art
[0002] With the rapid advancement of urbanization and industrialization, the amount of industrial sewage and domestic wastewater has greatly increased. If these sewage are discharged directly, they will pollute water resources. Therefore, sewage needs to be treated before it is discharged.
[0003] Purifying sewage through acid-base neutralization reactions can easily cause secondary pollution to the environment. Sewage can be treated secondary through photocatalysis. Photocatalysis is a method of treating sewage through photocatalytic oxidation technology. When the photocatalyst material is exposed to light, it will generate active oxides. These oxides can react with pollutants in sewage and oxidize and decompose them into harmless substances. However, in the process of photocatalysis of sewage treatment, the light source is required to be high. Long-term sewage treatment may cause the surface of the photocatalyst and the light-emitting part to be covered with dirt, resulting in poor sewage treatment effect of the photocatalyst.

[0029] In this 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 of treating sewage through photocatalytic oxidation technology. In the sewage treatment process, ultraviolet light is required to catalyze the photocatalyst. However, in the sewage treatment process, the sediment in the sewage may adhere to the surface of the first light-emitting unit 21 or the first reaction unit 22, thereby affecting the sewage treatment quality. This embodiment provides a sewage treatment device, such as Figure 1As shown, the sewage treatment device includes: a housing component 01. A first reaction component 02, the first reaction component 02 may include a first light-emitting unit 21, a first reaction unit 22, and a first spoiler unit 23. The first light-emitting unit 21 is detachably connected to the housing component 01. The first light-emitting unit 21 may be arranged in the hollow cavity of the housing component 01 to fix the relative position of the first light-emitting unit 21 and the housing unit. The first reaction unit 22 is detachably connected to the housing component 01. The first spoiler unit 23 is detachably connected to the housing component 01. The space surrounded by the first side wall of the first reaction unit 22 along the first direction and part of the housing component 01 may be a first chamber, and sewage may enter the first chamber from the water inlet 12. The space surrounded by the second side wall of the first reaction unit 22 along the first direction and part of the housing component 01 may be a third chamber, and the third chamber may be connected to the water outlet 13, so that the sewage may flow out from the water outlet 13 after treatment. The space surrounded by the two side walls of the first reaction unit 22 and part of the housing component 01 may be a second chamber, and the second chamber may purify the sewage. The first chamber can be connected to 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 connected to 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 that the first light-emitting unit 21 provides light energy to the first reaction unit 22. The first spoiler unit 23 can be arranged in the second chamber, so that the first spoiler unit 23 can convey airflow to the first light-emitting unit 21 and the first reaction unit 22.
[0030] The sewage treatment device may include a treatment state. The treatment state may include the first light-emitting unit 21 emitting ultraviolet light toward the first reaction unit 22, and providing a light source to the first reaction unit 22 through an ultraviolet lamp, so that the first reaction unit 22 can generate active oxides, thereby achieving the purpose of sewage treatment. The first spoiler unit 23 conveys airflow toward the first light-emitting unit 21 and the first reaction unit 22 respectively, and conveys airflow toward the first light-emitting unit 21 and the first reaction unit 22 through the first spoiler unit 23, and removes the sediment on the surface of the first light-emitting unit 21 and the first reaction unit 22 through the airflow, and at the same time, it can also stir the sewage to improve the effect of sewage treatment, and 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 housing component 01, and by contacting with the sewage, the toxic substances in the sewage are 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 this embodiment, the housing assembly 01 may include a housing 11, a water inlet 12, and a water outlet 13. The water inlet 12 and the water outlet 13 are detachably connected to the housing 11, such as Figure 2As shown, a valve 14 can be installed at the water inlet 12. The space surrounded by the first side of the first direction of the first reaction unit 22 and the part of the shell 11 can be a first chamber. The space surrounded by the first reaction unit 22 and the part of the shell 11 can be a second chamber, and the second chamber can purify the sewage. The space surrounded by the second side of the first direction of the first reaction unit 22 and the part of the shell 11 can be a third chamber. The water inlet 12 can be connected to the first chamber, so that the sewage can enter the first chamber from the water inlet 12. The water outlet 13 can be connected to the third chamber, so that the sewage can flow out from the water outlet 13 after treatment. 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 and the oxides in the sewage treatment device are in contact 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 spoiler unit 23 are respectively detachably connected to the shell 11. The first light-emitting unit 21, the first reaction unit 22, and the first spoiler 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 spoiler unit 23, so that the three can cooperate with each other during the reaction process, thereby achieving the purpose of sewage treatment. In other embodiments, the first light-emitting unit 21 may include a first light-emitting portion 211 and a first waterproof tube 212. The first light-emitting portion 211 and the first waterproof tube 212 can be arranged in the second chamber, and the first waterproof tube 212 can be sleeved on the surface of the first light-emitting portion 211 to prevent the first light-emitting portion 211 from directly contacting the sewage.
[0032] The treatment state may also include sewage entering the first chamber from the water inlet 12. Sewage may 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 may be located in the hollow cavity of the shell 11, so that the sewage in the hollow cavity of the shell 11 may 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 this embodiment, the first reaction unit 22 may include a first photocatalyst 221 and a second photocatalyst 222. The first photocatalyst 221 and the second photocatalyst 222 are detachably connected to the housing 11, respectively. The first photocatalyst 221 may be arranged on a side of the first light-emitting unit 21 close to the water inlet 12. The second photocatalyst 222 may be arranged on a side of the first light-emitting unit 21 close to the water outlet 13. Thus, when the sewage flows through the sewage treatment device, it may contact the first photocatalyst 221 and the second photocatalyst 222 in sequence, thereby improving the sewage treatment effect. The space surrounded by the first photocatalyst 221 and a part of the housing 11 may be a first chamber. The space surrounded by the first photocatalyst 221, the second photocatalyst 222 and a part of the housing 11 may be a second chamber. The space surrounded by the second photocatalyst 222 and a part of the housing 11 may be a third chamber.
[0034] The flow rate of the first photocatalyst 221 near the bottom of the shell 11 through the sewage can be a first flow rate. The flow rate of the first photocatalyst 221 near the top of the shell 11 through the sewage can be a second flow rate. The flow rate of the second photocatalyst 222 near the bottom of the shell 11 through the sewage can be a third flow rate. The flow rate of the second photocatalyst 222 near the top of the shell 11 through the sewage can be a fourth flow rate. The first flow rate can be less than the second flow rate, so that a large amount of sewage can enter the second chamber from the first photocatalyst 221 near the bottom of the shell 11. The third flow rate can be greater than the fourth flow rate, so that a large amount of sewage can enter the third chamber from the second photocatalyst 222 near the top of the shell 11. The combination of the two allows the sewage to stay in the second chamber for a longer time, that is, it is more fully in contact with the first photocatalyst 221 and the second photocatalyst 222, thereby improving the sewage treatment effect.
[0035] In the present embodiment, the first spoiler unit 23 may include a first spoiler 231. The first spoiler 231 is detachably connected to the housing 11. The first spoiler 231 may be disposed in the second chamber. The first spoiler 231 may be disposed at the bottom of the hollow cavity of the housing 11. The first spoiler 231 may output airflow into the second chamber, and the sediment on the surfaces of the first light-emitting unit 21, the first photocatalyst 221, and the second photocatalyst 222 may be removed by the airflow. At the same time, the first spoiler 231 may also stir the sewage, thereby preventing the sediment in the sewage from being deposited on the surfaces of the first light-emitting unit 21, the first photocatalyst 221, and the second photocatalyst 222, thereby improving the effect of sewage treatment.
[0036] In this embodiment, the first spoiler unit 23 may further include a second spoiler 232. The second spoiler 232 is detachably connected to the housing 11. The second spoiler 232 may be disposed on a side of the first reaction unit 22 away from the first spoiler 231, so that the bubbles generated by the first spoiler 231 may burst when contacting the second spoiler 232, further stirring the sewage, and preventing the sediment in the sewage from being deposited on the surface of the first light-emitting unit 21 and the first photocatalyst 221 and the second photocatalyst 222.
[0037] In this embodiment, the sewage treatment device may further include a second reaction component 03. The second reaction component 03 may be arranged in the third chamber. The second reaction component 03 may be spaced apart from the first reaction component 02. When the sewage passes through the second reaction component 03, the second reaction component 03 may treat the sewage again, thereby improving the treatment effect of the sewage. The second reaction component 03 may include a second light-emitting unit 31, a second reaction unit 32, and a second spoiler unit 33. The second light-emitting unit 31, the second reaction unit 32, and the second spoiler unit 33 are respectively detachably connected to 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 chamber may include a first area, a second area, and a third area. The space surrounded by the second reaction component 03 along the side close to the water inlet 12, the first reaction component 02 close to the side of the water outlet 13, and the part of the shell 11 may be the first area, and the sewage may enter the first area from the second cavity. The space surrounded by the two side walls of the second reaction component 03 and the part of the shell 11 may be the second area. The space surrounded by the second reaction component 03 near the water outlet 13 and part of the shell 11 can be the third area. The second chamber can be connected to the first area through the first reaction unit 22 near the water outlet 13. The first area can be connected to the second area through the first side wall of the second reaction unit 32 near the water inlet 12 along the first direction. The second area can be connected to the third area through the second reaction unit 32 near the water outlet 13. The sewage flows from the first area to the third area, so that the sewage can pass through the second reaction component 03 during the flow process, so as to treat the sewage again, further improving the sewage treatment effect. The second light-emitting unit 31 can be arranged in the second area, and the second spoiler unit 33 can be arranged in the second area, so that the second light-emitting part 311 can provide light sources for both side walls of the second reaction component 03 at the same time. In other embodiments, the second light-emitting unit 31 can also include a second waterproof tube 312 to prevent the second light-emitting part 311 from being directly exposed to the sewage.
[0038] The treatment state may also include sewage passing through the first area, the second area, and the third area in sequence.
[0039] In this embodiment, the second reaction unit 32 may include a third photocatalyst 321 and a fourth photocatalyst 322. The third photocatalyst 321 and the fourth photocatalyst 322 are respectively detachably connected to the housing 11, thereby fixing the relative positions of the third photocatalyst 321 and the fourth photocatalyst 322. The third photocatalyst 321 may be arranged on a side of the second light-emitting unit 31 close to the water inlet 12. The fourth photocatalyst 322 may be arranged on a 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 component 02, and a part of the housing 11 may be the first area. The space surrounded by the third photocatalyst 321, the fourth photocatalyst 322, and a part of the housing 11 may be the second area. The space surrounded by the fourth photocatalyst 322 and a part of the housing 11 may be the third area. The flow rate of the sewage passing through the third photocatalyst 321 near the bottom of the housing 11 may be the fifth flow rate. The flow rate of the sewage through the third photocatalyst 321 near the top of the shell 11 can be the sixth flow rate. The flow rate of the sewage through the fourth photocatalyst 322 can be the seventh flow rate. The flow rate of the sewage through each part of the third photocatalyst 321 is the same, so that the sewage flowing from the third photocatalyst 321 into the third area can pass through the fourth photocatalyst 322 evenly, preventing the sewage from flowing out directly from the outlet 13 and staying in the third interval for too short a time, thereby affecting the sewage treatment quality. At the same time, due to the reaction of the substances produced by the sewage and the photocatalyst, tiny precipitates will be generated. This part of the precipitate may cause blockage to the path for the sewage to pass through the third photocatalyst 321, so the seventh flow rate can be slightly larger, that is, the aperture on 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 area for a longer time, improving the sewage treatment effect in the second area. The seventh flow rate can be less than the fifth flow rate and greater than the sixth flow rate, so that the overall flow rates at the third photocatalyst 321 and the fourth photocatalyst 322 are similar in size, preventing the sewage pressure in the second interval from being too large or too small. In other embodiments, the housing assembly 01 may also include a first groove 15 and a second groove 16. The first groove 15 may be arranged in the second interval and fixedly connected to the bottom end of the shell 11. The second groove 16 may be arranged in the third interval and fixedly connected to the bottom end of the shell 11. When the sewage flows through the second interval, the sediment in the sewage can be deposited in the first groove 15. When the sewage passes through the third interval, the sediment in the sewage can be deposited in the second groove 16, further improving the sewage treatment effect.
[0040] In this embodiment, the second spoiler unit 33 may include a third spoiler 331. The third spoiler 331 is detachably connected to the housing 11. The third spoiler 331 is disposed in the second region. The third spoiler 331 may be spaced apart from the bottom end of the hollow cavity of the housing 11.
[0041] The treatment state may include the third spoiler 331 conveying airflow toward the bottom of the shell 11, so that the airflow can first move toward the direction close to the bottom of the shell 11, and then move toward the direction close to the top of the shell 11 under the action of buoyancy, increasing the moving path of the airflow in the second area and improving the spoiler effect of the airflow. The sediment on the surface of the second light-emitting unit 311, the third photocatalyst 321, and the fourth photocatalyst 322 is removed by the airflow, and the airflow can also stir the sewage to prevent the sediment in the sewage from being deposited on the surface of the second light-emitting unit 31 and the third photocatalyst 321 and the fourth photocatalyst 322, thereby improving the effect of sewage treatment.
[0042] In this embodiment, the second spoiler unit 33 further includes a fourth spoiler 332. The fourth spoiler 332 is disposed on a side of the second reaction unit 32 away from the bottom end of the housing 11, so that the bubbles generated by the third spoiler 331 can burst when contacting the fourth spoiler 332, further stirring the sewage, and preventing the sediment in the sewage from being deposited on the surfaces of the second light-emitting unit 31, the third photocatalyst 321, and the fourth photocatalyst 322.
[0043] In this embodiment, the sewage treatment device may further include a first heating component 04. The first heating component 04 is detachably connected to the housing 11. The first heating component 04 may be disposed in the first region. By arranging the first heating component 04 to heat the sewage, the reaction rate between the toxic substances in the sewage and the substances generated by the photocatalyst may be increased, the decomposition of the toxic substances in the sewage may be promoted, and the effect of sewage treatment may be improved.
[0044] In this embodiment, the sewage treatment device may further include a second heating component 05. The second heating component 05 is detachably connected to the housing component 01. The second heating component 05 may be disposed in the first chamber. By arranging the first heating component 04 to heat the sewage, the reaction rate between the toxic substances in the sewage and the substances produced by the photocatalyst may be increased, the decomposition of the toxic substances in the sewage may be promoted, and the sewage treatment effect may be improved. At the same time, the increase in temperature may also expand the volume of the air in the airflow generated by the third spoiler, that is, the volume of the bubbles generated may increase, further improving the spoiler effect of the third spoiler 331.
