Description

Technical Field

[0001] The present application relates to the field of sewage treatment technology, and in particular to a sewage treatment device based on the high adsorption performance of activated carbon. Background Art

[0002] A large amount of sewage generated in social production and life needs to be treated before it can be discharged or recycled. Among them, the wastewater generated in the printing and dyeing industry contains a large amount of pigments. The pigments in the sewage are usually treated by adsorption of activated carbon with high adsorption performance.

[0003] However, the adsorption capacity of activated carbon is limited. As the pigment adsorption of activated carbon gradually reaches saturation, the activated carbon needs to be replaced to ensure the treatment needs of the pigments in the wastewater. This is more troublesome and reduces the treatment efficiency. Therefore, a sewage treatment equipment with a longer service life of activated carbon is needed. Utility Model Content

[0004] In order to extend the service life of activated carbon in sewage treatment equipment, the present application provides a sewage treatment equipment based on the high adsorption performance of activated carbon.

[0005] The present application provides a sewage treatment equipment based on the high adsorption performance of activated carbon, which adopts the following technical solution:

[0006] A sewage treatment device based on the high adsorption performance of activated carbon comprises a tank body, an activated carbon layer and a ventilation pipe; the upper part of the tank body is provided with a water inlet pipe, and the lower part is provided with a water outlet pipe; the activated carbon layer is connected to the inner wall of the tank body; the ventilation pipe is connected to the inner wall of the tank body, and the ventilation pipe is used for allowing ozone to pass through.

[0007] By adopting the above technical solution, when treating sewage, the sewage is introduced into the tank from the water inlet pipe, and the sewage passes through the activated carbon layer in the pipe body and flows down to the outlet pipe for discharge. While the sewage is introduced, ozone is introduced into the ventilation pipe, and ozone is used to oxidize part of the pigments in the sewage and part of the pigments adsorbed on the activated carbon, thereby extending the service life of the activated carbon and reducing the replacement frequency of the activated carbon, so as to ensure the treatment efficiency of the sewage treatment equipment.

[0008] Optionally, the activated carbon layer is provided with multiple layers, and the multiple layers of activated carbon layers are arranged at intervals along the height direction of the tank body.

[0009] By adopting the above technical solution, the sewage is treated multiple times using multiple layers of activated carbon to ensure the treatment effect of the sewage treatment equipment on the sewage.

[0010] Optionally, a plurality of ventilation pipes are provided, and the plurality of ventilation pipes and the plurality of activated carbon layers are spaced apart from each other.

[0011] By adopting the above technical scheme, on the one hand, the oxidation effect of ozone on the pigments in the activated carbon layer is ensured; on the other hand, if a certain activated carbon layer adsorbs too much pigment, ozone can be introduced into the ventilation pipe below the activated carbon separately to oxidize a part of the pigments adsorbed in the activated carbon layer, thereby further improving the service life of the activated carbon in the sewage treatment equipment.

[0012] Optionally, a plurality of branch pipes are connected to the circumference of the ventilation pipe, and the lumens of the branch pipes are interconnected with the lumen of the ventilation pipe.

[0013] By adopting the above technical solution, the ozone in the ventilation pipe is diffused into the tank body through multiple branch pipes, thereby improving the uniformity of the distribution of ozone in the tank body and sewage, thereby improving the effect of ozone oxidation pigments.

[0014] Optionally, the ventilation pipe is rotatably connected to the inner wall of the tank body.

[0015] By adopting the above technical solution, after the sewage is introduced, the flow of sewage drives the ventilation pipe to rotate relative to the tank body, so that after the ozone flows out from the branch pipe, it not only has a speed in the direction of the branch pipe, but also a speed in the direction of rotation of the ventilation pipe.

[0016] Optionally, the branch pipe includes a rigid portion and a flexible portion, the rigid portion is connected to the ventilation pipe, and the flexible portion is connected to an end of the rigid portion away from the ventilation pipe.

[0017] By adopting the above technical solution, after ozone is introduced into the branch pipe, the ozone forms a certain support for the flexible part. According to the different speeds of the ozone introduced into the branch pipe, the degree to which the branch pipe is supported is also different, so that the position where the ozone enters the tank body can be adjusted to a certain extent, thereby improving the flexibility of use of the vent pipe and the branch pipe; wherein the rigid part makes the flexible part relatively located in the middle position of the tank body, so as to improve the uniformity of distribution of ozone in the tank body.

[0018] Optionally, the flexible portion is made of elastic material.

[0019] By adopting the above technical solution, the volume of the flexible part can be changed according to the flow rate of the ozone introduced into the branch pipe, thereby further improving the flexibility of use of the ventilation pipe and the branch pipe.

[0020] Optionally, the end of the branch pipe away from the ventilation pipe is closed, and a plurality of air holes are formed through the side wall of the branch pipe.

[0021] By adopting the above technical solution, ozone is diffused into the tank body through the pores, further improving the distribution uniformity of ozone in the tank body.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting a vent pipe for introducing ozone in the tank body, when sewage is introduced into the tank body, ozone is introduced into the tank body through the vent pipe, and ozone is used to oxidize the sewage and neutralize part of the pigment adsorbed on the activated carbon layer, thereby improving the service life of the activated carbon layer in the sewage treatment equipment;

[0024] 2. By setting multiple branch pipes around the ventilation pipe, the uniformity of ozone distribution in the sewage and the tank is improved, thereby improving the oxidation effect of ozone on pigments;

[0025] 3. The branch pipe includes a rigid part and a flexible part, which improves the uniformity of ozone distribution in sewage and the tank body while providing flexibility in the use of the vent pipe and the branch pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a sewage treatment device based on the high adsorption performance of activated carbon. Figure 1 A sewage treatment device based on high adsorption performance of activated carbon includes a tank body 1, an activated carbon layer 2 and a vent pipe 3. The upper part of the tank body 1 is provided with a water inlet pipe 11, and the lower part is provided with a water outlet pipe 12. The activated carbon layer 2 is connected to the inner wall of the tank body 1, and the vent pipe 3 is connected to the inner wall of the tank body 1, and the vent pipe 3 is used for ozone to pass through.

[0031] When treating sewage, the sewage is introduced into the tank body 1 from the water inlet pipe 11. The sewage passes through the activated carbon layer 2 in the pipe body and then flows down to the water outlet pipe 12 for discharge. While the sewage is introduced, ozone is introduced into the ventilation pipe 3. Ozone is used to oxidize some pigments in the sewage and some pigments adsorbed on the activated carbon, thereby extending the service life of the activated carbon and reducing the replacement frequency of the activated carbon, so as to ensure the treatment efficiency of the sewage treatment equipment.

[0032] In this embodiment, in order to ensure the effect of sewage treatment, the activated carbon layer 2 is provided with multiple layers, and the multiple activated carbon layers 2 are arranged at intervals along the height direction of the tank body 1. Correspondingly, multiple ventilation pipes 3 are provided, and the multiple ventilation pipes 3 are arranged at intervals along the height direction of the tank body 1, and the multiple ventilation pipes 3 and the multiple activated carbon layers 2 are arranged at intervals from each other.

[0033] It is understandable that, when the height of the tank body 1 is relatively small, only one activated carbon layer 2 and one ventilation pipe 3 may be provided. In this case, the ventilation pipe 3 is preferably provided above the activated carbon layer 2, so that after the ozone is introduced into the tank body 1, the pigment in the sewage is first oxidized, thereby reducing the pigment attached to the activated carbon layer 2, and further extending the service life of the activated carbon.

[0034] In this embodiment, ozone can be introduced into each ventilation pipe 3 separately, or a main pipe can be set on the outer wall of the tank body 1 to connect multiple ventilation pipes 3 through the main pipe, and ozone can be introduced into each ventilation pipe 3 at the same time by introducing ozone into the main pipe.

[0035] Furthermore, a plurality of branch pipes 31 are connected to the periphery of the ventilation pipe 3, and the lumens of the branch pipes 31 are connected to the lumens of the ventilation pipe 3. Ozone is introduced into the branch pipes 31 through the ventilation pipe 3 and enters the tank body 1 through the branch pipes 31, thereby improving the uniformity of the distribution of ozone in the sewage, thereby improving the oxidation effect of ozone on pigments.

[0036] Furthermore, the ventilation pipe 3 is rotatably connected to the inner wall of the tank body 1. After the sewage is introduced, the ventilation pipe 3 is driven to rotate relative to the tank body 1 during the flow of the sewage, so that after the ozone flows out from the branch pipe 31, it has not only a speed in the direction of the branch pipe 31, but also a speed in the rotation direction of the ventilation pipe 3, thereby further improving the uniformity of the distribution of ozone in the sewage and improving the oxidation effect of ozone on pigments.

[0037] Reference Figure 2 Furthermore, the branch pipe 31 includes a rigid portion 311 and a flexible portion 312, wherein the rigid portion 311 is connected to the vent pipe 3, and the flexible portion 312 is connected to the end of the rigid portion 311 away from the vent pipe 3. With this design, after ozone is introduced into the branch pipe 31, the ozone forms a certain support for the flexible portion 312, and the degree to which the branch pipe 31 is supported varies according to the speed of ozone introduced into the branch pipe 31, so that the position where ozone enters the tank body 1 can be adjusted to a certain extent, thereby improving the flexibility of use of the vent pipe 3 and the branch pipe 31.

[0038] In this embodiment, the flexible portion 312 is made of elastic material, so that the volume of the flexible portion 312 can be changed according to the flow rate of ozone entering the branch pipe 31, further improving the flexibility of use of the vent pipe 3 and the branch pipe 31. The material of the flexible portion 312 includes but is not limited to rubber, latex or Oxford cloth.

[0039] Furthermore, the end of the branch pipe 31 away from the vent pipe 3 is closed, and a plurality of air holes 313 are provided on the side wall of the branch pipe 31, so that ozone can diffuse into the tank body 1 through the air holes 313, further improving the uniformity of the distribution of ozone in the tank body 1. In this embodiment, the plurality of air holes 313 are evenly distributed in the rigid portion 311 and the flexible portion 312.

[0040] The implementation principle of a sewage treatment device based on the high adsorption performance of activated carbon in an embodiment of the present application is as follows: when treating sewage, the sewage is introduced into the tank body 1 from the water inlet pipe 11, and at the same time, ozone is introduced into the tank body 1 through the ventilation pipe 3 and the branch pipe 31. The ozone diffuses into the sewage and the activated carbon layer 2, and a part of the pigment in the sewage and a part of the pigment adsorbed on the activated carbon layer 2 are oxidized to extend the service life of the activated carbon in the sewage treatment equipment. After passing through the multiple layers of activated carbon layers 2 and the ventilation pipes 3, the sewage can be discharged from the water outlet pipe 12.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
