[0033] See also Figure 1 to Figure 2An embodiment of the present application provides a sewage treatment device, including a first container 100, an ozone intake mechanism 200 and a sewage introduction mechanism 300, the first container 100 has a first chamber 110, a second chamber 120 and a first discharge port 130, the first chamber 110 is connected to the second chamber 120, and the second chamber 120 is provided with a first catalytic module 121 and is connected to the first discharge port 130; the ozone intake mechanism 200 is arranged in the first chamber 110 and is provided with an air inlet 210, and the ozone intake mechanism 200 is used to introduce ozone from the air inlet 210 into the first chamber 110; the sewage introduction mechanism 300 is arranged in the first chamber 110 and is located on a side of the ozone intake mechanism 200 away from the second chamber 120, the sewage introduction mechanism 300 is provided with a water inlet 310, and the sewage introduction mechanism 300 is used to introduce sewage from the water inlet 310 into the first chamber 110.

[0034] In the above-mentioned sewage treatment device, the ozone air intake mechanism 200 and the sewage introduction mechanism 300 respectively introduce ozone and sewage into the first chamber 110, the ozone and sewage are mixed in the first chamber 110 and a preliminary oxidation reaction is performed on the harmful substances in the sewage. Subsequently, the mixed ozone and sewage enter the second chamber 120, and the ozone forms hydroxyl radicals under the catalytic action of the first catalytic module 121. The hydroxyl radicals react with the harmful substances in the sewage again to remove the harmful substances in the sewage. The treated sewage is discharged from the first outlet 130. In order to carry out subsequent treatment of sewage; in this process, since the sewage introduction mechanism 300 is located on the side of the ozone intake mechanism 200 away from the second chamber 120, when the sewage flows from the water inlet 310 into the first chamber 110 and flows to the second chamber 120, the flow of sewage can drive the ozone at the air inlet 210 to move together, so as to reduce the movement resistance of ozone, so that ozone can quickly enter the second chamber 120, accelerate the catalytic process of ozone by the first catalytic module 121 and generate more hydroxyl radicals, thereby fully oxidizing harmful substances in sewage. Compared with traditional technologies, the above-mentioned sewage treatment device can generate more hydroxyl radicals to remove harmful substances in sewage and improve the sewage treatment effect.

[0035] For explanation, after the sewage and ozone enter the first chamber 110, a preliminary oxidation reaction will first be carried out in the first chamber 110. During this process, a small amount of harmful substances in the sewage are oxidized by ozone. Subsequently, the sewage and ozone are mixed and enter the second chamber 120 together. The first catalytic module 121 catalyzes the ozone to generate hydroxyl radicals, which then undergo an oxidation reaction with the sewage entering the second chamber 120 to fully remove the harmful substances in the sewage.

[0036] For further information, see Figure 2The first container 100 is vertically arranged so that the first discharge port 130, the second chamber 120, and the first chamber 110 are arranged in sequence along the gravity direction. The water inlet 310 of the sewage introduction mechanism 300 is arranged at the bottom of the first container 100, and the air inlet 210 of the ozone intake mechanism 200 is located on the side of the water inlet 310 away from the bottom of the first container 100. In this way, when the sewage enters the first chamber 110 from the water inlet 310, the sewage will form an upward flow, which will not only avoid forming dead water, but also reduce the rising resistance of ozone at the air inlet 210, thereby driving the ozone to enter the second chamber 120 faster, thereby accelerating the catalytic oxidation process.

[0037] Furthermore, the water inlet 310 and the air inlet 210 are both arranged toward the second chamber 120, so that the sewage and ozone have a tendency to move toward the second chamber 120 when entering the first chamber 110; in addition, the water inlet 310 is arranged toward the second chamber 120, which can also prevent the sewage from forming stagnant water and polluting the space within the first container 100.

[0038] See also Figure 1 In one embodiment, the sewage treatment device also includes a second container 400, the second container 400 has a third chamber 410, a fourth chamber 420 and a second discharge outlet 430, the third chamber 410 is connected to the first discharge outlet 130 and to the fourth chamber 420, and the fourth chamber 420 is provided with a second catalytic module 421 and is connected to the second discharge outlet 430.

[0039] The sewage treated by the first container 100 enters the third chamber 410 of the second container 400 through the first outlet 130, and then enters the fourth chamber 420 from the third chamber 410. The second catalytic module 421 in the fourth chamber 420 can catalyze the remaining ozone in the sewage again to form hydroxyl radicals, thereby further oxidizing and removing harmful substances in the sewage.

[0040] In the above embodiment, the provision of the third chamber 410 can provide a certain buffering effect for the sewage entering the second container 400, and the sewage and ozone can be further oxidized and mixed in the third chamber 410, thereby improving the removal effect of harmful substances in the sewage.

[0041] See also Figure 1 In one embodiment, the second container 400 is provided with at least two second discharge ports 430 of the preceding second container 400 are connected to the third chamber 410 of the following second container 400 .

[0042] By providing at least two second containers 400 , harmful substances in sewage can be further removed, thereby ensuring the sewage treatment effect.

[0043] In one embodiment, different types of second catalytic modules 421 are disposed in different second containers 400, so as to utilize multiple catalysts connected in series to remove different types of harmful substances in sewage.

[0044] Furthermore, the second outlet 430 of the last second container 400 is connected to the digestion tank 510, and the digestion tank 510 is used to consume the remaining hydroxyl radicals in the sewage.

[0045] Furthermore, the top of the last second container 400 is connected to the tail gas destroyer 520, and the tail gas destroyer 520 is used to destroy the tail gas generated during the reaction process to prevent the tail gas from entering the air and polluting the air.

[0046] See also Figures 1 to 3 In one embodiment, the ozone inlet mechanism 200 includes a pipeline module 220 , which is used to communicate with the ozone generating device 250 , and the pipeline module 220 has an air inlet 210 disposed on its wall.

[0047] The ozone generated by the ozone generating device 250 enters the pipeline module 220 and enters the first chamber 110 from the air inlet 210 on the pipeline module 220, so that the ozone introduction process is reliable and the implementation cost is low.

[0048] Optionally, the pipeline module 220 can be a pipeline arranged in a bent manner, or a pipeline extending in a straight line, or a pipeline arranged in a crossed manner, or a pipeline arranged in a winding manner, which is not specifically limited here.

[0049] See also Figure 3 In one embodiment, the ozone inlet mechanism 200 includes a main pipeline 221 and a branch pipeline 222. The main pipeline 221 is used to communicate with the ozone generating device 250. The branch pipelines 222 are provided with at least two and are connected to the main pipeline 221, and all the branch pipelines 222 are arranged at intervals along the axial direction of the main pipeline 221. The air inlet 210 is provided with at least two and is spaced apart from the main pipeline 221 and / or the branch pipeline 222.

[0050] The main pipeline 221 is connected to the ozone generator 250 to introduce the ozone generated by the ozone generator 250 into at least two branch pipelines 222, and the ozone then enters the first chamber 110 from the air inlet 210. The setting of the main pipeline 221 and at least two branch pipelines 222 can make the ozone evenly distributed in the first chamber 110, ensuring that the ozone and sewage can be fully mixed.

[0051] As a supplementary explanation, at least two air inlets 210 are provided, and the air inlet 210 is provided in at least one of the main pipeline 221 and the branch pipeline 222 to ensure the uniformity of air intake.

[0052] See also Figure 3In one embodiment, the ozone inlet mechanism 200 further includes a first mounting rod 231, a second mounting rod 232 and a third mounting rod 233. The first mounting rod 231 and the second mounting rod 232 are parallel and spaced apart in the first chamber 110. One end of the third mounting rod 233 is disposed on the first mounting rod 231, and the other end of the third mounting rod 233 is disposed on the second mounting rod 232. The main line 221 is disposed on the third mounting rod 233, and one end of the branch line 222 is disposed on the first mounting rod 231, and the other end of the branch line 222 is disposed on the second mounting rod 232.

[0053] The first mounting rod 231 is connected to the second mounting rod 232 through the third mounting rod 233, the main pipeline 221 is arranged on the third mounting rod 233, one end of the branch pipeline 222 is arranged on the first mounting rod 231, and the other end of the branch pipeline 222 is arranged on the second mounting rod 232. In this way, effective support can be provided for the pipeline module 220, ensuring the installation strength of the pipeline module 220 in the first chamber 110 and preventing the pipeline module 220 from being damaged.

[0054] In one embodiment, the main pipeline 221 is overlapped on the side wall of the third mounting rod 233, and the third mounting rod 233 can play a certain supporting role for the main pipeline 221 to ensure the installation strength of the main pipeline 221; the branch pipeline 222 is provided with at least two and is arranged at intervals along the axial direction of the first mounting rod 231, and the opposite ends of the branch pipeline 222 are overlapped on the first mounting rod 231 and the second mounting rod 232 respectively to ensure the installation strength of the branch pipeline 222.

[0055] See also Figure 2 and Figure 4 In one embodiment, the sewage treatment device further includes a partition 600, which is disposed in the first container 100 and separates the inner cavity of the first container 100 into a first chamber 110 and a second chamber 120. The partition 600 is provided with at least two through holes 610, and the first chamber 110 is connected to the second chamber 120 through the through holes 610.

[0056] The first chamber 110 and the second chamber 120 are connected through the through hole 610 on the partition 600. The sewage mixed with ozone enters the second chamber 120 from the first chamber 110 through the through hole 610 for subsequent catalytic reaction. At least two through holes 610 on the partition 600 can make the sewage mixed with ozone enter the second chamber 120 more dispersedly and evenly, thereby ensuring the subsequent catalytic effect.

[0057] Specifically, see Figure 4 A plurality of through holes 610 are provided and evenly arranged on the partition 600 , so that the sewage mixed with ozone can enter the second chamber 120 evenly and dispersedly.

[0058] See also Figure 2 , Figure 4 and Figure 5 In one embodiment, the sewage treatment device further includes a dispersion member 700, which is provided with at least two dispersion members 700 and is arranged one-to-one with the through holes 610. The dispersion member 700 includes a mesh cover 710, a liquid infusion tube 720 and a mounting plate 730. The mesh cover 710 is provided on one side of the mounting plate 730 to form a mixing chamber. The liquid infusion tube 720 is provided on the other side of the mounting plate 730 and is connected to the mixing chamber. The mesh cover 710 is provided with at least two communication ports 711, and all the communication ports 711 are arranged at intervals along the circumference of the mesh cover 710. The liquid infusion tube 720 is passed through the through hole 610.

[0059] At least two spaced communication ports 711 are provided around the mesh cover 710. Thus, when the sewage mixed with ozone in the first chamber 110 enters the mixing chamber formed by the mesh cover 710 and the mounting plate 730 through the infusion tube 720, it can enter the second chamber 120 through the at least two communication ports 711. The at least two communication ports 711 provided around the mesh cover 710 can have a certain dispersion effect on the sewage mixed with ozone, so that the sewage mixed with ozone can enter the second chamber 120 more evenly and come into contact with the first catalytic module 121 more evenly for catalytic reaction, thereby ensuring the subsequent catalytic effect.

[0060] Specifically, see Figure 5 The mesh cover 710 is umbrella-shaped and is arranged on the side of the mounting plate 730 away from the infusion tube 720, and a plurality of connecting ports 711 are arranged on the side wall of the mesh cover 710 at intervals along the circumference of the mesh cover 710. In this way, the sewage mixed with ozone can enter the second chamber 120 through the plurality of connecting ports 711 at the same time, ensuring the uniformity of the sewage entering the second chamber 120 and further improving the subsequent catalytic and oxidation effects.

[0061] Furthermore, the communication port 711 on the mesh cover 710 can also filter some of the granular matter in the sewage to prevent the granular matter from affecting the catalytic effect of the first catalytic module 121 .

[0062] See also Figure 5 In one embodiment, a limiting portion 740 is provided at the outer edge of one end of the infusion tube 720 away from the mounting plate 730 , and the limiting portion 740 is used to abut against the outer edge of the through hole 610 .

[0063] The limiting portion 740 disposed at one end of the infusion tube 720 away from the mounting plate 730 can abut against the outer edge of the through hole 610 to limit the axial movement of the infusion tube 720 along the through hole 610 and to prevent the dispersion member 700 from being separated from the through hole 610 under the flow of sewage.

[0064] Furthermore, the limiting portion 740 includes a protrusion provided on the outer edge of the end of the infusion tube 720 away from the mounting plate 730 , and the protrusion can resist the outer edge of the through hole 610 to prevent the infusion tube 720 from falling off from the through hole 610 .

[0065] Understandably, see Figure 1 The partition 600 and the dispersion member 700 in the above embodiment may also be disposed in the second container 400, which will not be described in detail here.

[0066] See also Figure 2 In one embodiment, the ozone inlet mechanism 200 further includes an aeration head 240, which is disposed at the air inlet 210. The aeration head 240 can fully dissolve ozone in the sewage, increase the contact area between ozone and sewage, and make the oxidation process more complete.

[0067] By way of explanation, the aeration head 240, as a special sewage treatment element, can reduce the size of bubbles, increase the number of bubbles, increase the turbulence of the liquid, and prolong the contact time between the bubbles and the sewage so as to fully dissolve the ozone in the sewage.

[0068] In one embodiment, the sewage treatment device further includes a drain valve. A drain port is provided at the bottom of the first container 100. The drain valve is provided at the drain port and is used to open or close the drain port.

[0069] The interior of the first container 100 needs to be cleaned regularly. By providing a drain port and a drain valve, not only the sewage inside can be drained before cleaning, but also the cleaning liquid inside can be drained after cleaning, and the process is convenient and reliable.

[0070] Specifically, a cleaning liquid such as tap water is pumped into the first container 100 by a high-pressure water pump. At this time, the drain valve is closed to prevent the cleaning liquid from flowing out. After cleaning is completed, the drain valve is opened to discharge the cleaning liquid. In specific implementation, repeated flushing is required to ensure the cleaning effect.

[0071] Furthermore, a ball valve and a breathing valve are provided above the first container 100. When discharging the cleaning liquid, the ball valve and the breathing valve above need to be opened to discharge the cleaning liquid.

[0072] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
