Multi-stage wastewater dephenolization includes pretreatment, primary physical and chemical treatment, secondary deep physical and chemical treatment and post-treatment. Wastewater dephenolization can recover phenolic compounds and prevent water and soil pollution.

The bottom of the airbag is connected to the air intake pipe.

[0018] A wastewater dephenolization classification treatment method is applied to the above-mentioned wastewater dephenolization classification treatment device, and the steps are as follows:

[0019] S1. Adding extractant: first add the extractant into the extraction tower from the extractant pipe, the extractant forms a relatively stable environment in the tower, then add wastewater from the wastewater pipe, the wastewater immediately contacts with the extractant after being added, the extraction process is quickly started, and the extraction efficiency is improved;

[0020] S2. Accelerated mixing: The sieve plate fluctuates up and down, and the sieve holes on the sieve plate disperse the extractant and wastewater into small droplets, increasing the contact area between the wastewater and the extractant. At the same time, the sieve holes on the sieve plate make the liquid flow evenly throughout the extraction tower body.

[0021] S3, convection mixing; by making two adjacent sieve plates slide in the positive sieve mixing track and the reverse sieve mixing track respectively, since the positive sieve mixing track and the reverse sieve mixing track are in opposite directions, the two adjacent sieve plates move in opposite directions, and the adjacent sieve plates make the liquid flow in opposite directions, so that the liquid in the extraction tower body is convective, so as to accelerate the mixing efficiency of the wastewater and the extractant, that is, to improve the dephenolization efficiency;

[0022] S4, sieve hole blockage and track change: precipitation occurs during the extraction process, and the precipitation enters the filter holes of the sieve plate, causing blockage. At this time, the movement of the sieve plate is subject to great resistance from the liquid in the extraction tower body. When the sieve plate moves downward and the ball moves to the highest point of the positive sieve mixing track, the reaction force of the liquid on the sieve plate is greater than the resistance of the obstruction block to the ball. At this time, the ball presses the obstruction block into the slide groove, and the ball enters the vibration track;

[0023] S5. Vibration separation: Since the vibration track adopts a sinusoidal structure, the balls move back and forth rapidly along the vibration track, so that the sieve plate vibrates rapidly. In the process of the balls moving up and down, the pressure ring collides with the sealing ring, further improving the vibration effect to remove the sediment in the sieve hole.

[0024] Compared with the prior art, the present invention has at least one of the following beneficial technical effects:

[0025] When the precipitate produced by extraction is blocked in the sieve holes of the sieve plate, the resistance to the up and down movement of the sieve plate increases. At this time, the force of water acting on the sieve plate is greater than the resistance of the obstruction block, so that the ball enters the vibration track and vibrates rapidly. In the process of the ball moving up and down, the pressure ring collides with the sealing ring, further improving the vibration effect, so as to vibrate and discharge the precipitate in the sieve holes.

[0026] Furthermore, by sliding two adjacent sieve plates in the positive screening and mixing track and the reverse screening and mixing track respectively, the two adjacent sieve plates move in opposite directions, so that the adjacent sieve plates make the liquid flow in opposite directions, so that liquid convection occurs in the extraction tower body to accelerate the mixing efficiency of wastewater and extractant, that is, to improve the dephenolization efficiency.

[0027] Furthermore, the air bag is used to increase the air pressure inside the slide, and the pressure ring and the sealing ring are used to improve the sealing, so as to prevent the liquid inside the extraction tower body from seeping into the slide, causing the vibration clearing parts inside the slide to be corroded and unable to operate normally.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Example 1

[0042] This embodiment provides a wastewater dephenolization classification treatment device, such as Figure 1 As shown, it includes an extraction tower body 1, an extractant pipe 2 for introducing an extractant is fixedly installed on the tower body of the extraction tower body 1 and near the bottom, a wastewater pipe 3 for introducing wastewater is fixedly installed on the tower body of the extraction tower body 1 and above the extractant pipe 2, and a capping cover 4 is fixedly installed on the top of the extraction tower body 1.

[0043] First, add the extractant into the extraction tower body 1 from the extractant pipe 2. The extractant forms a relatively stable environment in the tower. Then add wastewater from the wastewater pipe 3. After the wastewater is added, it immediately contacts with the extractant, and the extraction process is quickly started to improve the extraction efficiency.

[0044] like Figure 2-Figure 4 As shown, an accelerating mixing element 5 is arranged inside the extraction tower body 1, and the accelerating mixing element 5 includes a rotating shaft 51, a screening and mixing assembly, a positive screening and mixing track 56 and a guide bar 58. Both ends of the rotating shaft 51 are rotatably connected to the extraction tower body 1, a screening and mixing assembly is arranged in the middle of the rotating shaft 51, a positive screening and mixing track 56 is opened in the middle of the rotating shaft 51, and the screening and mixing assembly slides along the positive screening and mixing track 56. A guide bar 58 is fixedly installed inside the extraction tower body 1, and the screening and mixing assembly slides up and down along the positive screening and mixing track 56, and the screening and mixing assembly contacts the wastewater and the extractant.

[0045] like Figure 3 As shown, multiple sun drying and mixing components are provided and are equidistantly distributed in a straight line along the rotating shaft 51. The screening and mixing components include a slide cylinder 52 and a sieve plate 53. The slide cylinder 52 slides up and down in the middle of the rotating shaft 51. The sieve plate 53 is fixedly installed in the middle of the slide cylinder 52. Wastewater and extractant flow through the sieve holes of the sieve plate 53. The inner arc surface of the slide cylinder 52 is rollingly connected to the ball 55.

[0046] A motor is provided at the top of the rotating shaft 51, which drives the rotating shaft 51 to rotate so that the sieve plate 53 slides up and down along the positive screening and mixing track 56, and the extractant and wastewater are dispersed into small droplets through the sieve holes on the sieve plate 53, thereby increasing the contact area between the wastewater and the extractant. At the same time, the sieve holes on the sieve plate 53 allow the liquid to flow evenly in the entire extraction tower body 1.

[0047] like Figure 4 and Figure 5 As shown, the vibration clearing member 6 includes a vibration track 61, a connecting port 62, an obstruction block 63, a slide groove 66 and a resistance spring 67. The connecting port 62 is opened in the middle of the rotating shaft 51, the bottom end of the connecting port 62 is connected to the positive screening and mixing track 56, and the top of the connecting port 62 is connected to the vibration track 61. A slide groove 66 is opened in the middle of the rotating shaft 51 and located at the connecting port 62. The inside of the slide groove 66 is slidably connected to the obstruction block 63, and the resistance spring 67 is elastically connected between the obstruction block 63 and the rotating shaft 51.

[0048] like Figure 6 As shown, the vibration track 61 and the positive screening and mixing track 56 both adopt a sinusoidal wave structure. The amplitude of the sinusoidal wave structure formed by the vibration track 61 is smaller than the amplitude of the sinusoidal wave structure formed by the positive screening and mixing track 56. The period of the sinusoidal wave structure formed by the vibration track 61 is smaller than the period of the sinusoidal wave structure formed by the positive screening and mixing track 56. Balls 55 are arranged inside the screening and mixing component. Initially, the balls 55 slide in the positive screening and mixing track 56. When the screening and mixing component is blocked, the balls 55 enter the vibration track 61 and slide.

[0049] The lowest point of the vibration track 61 and the highest point of the positive screening track 56 are connected to each other through the connecting port 62 . The blocking block 63 is located between the vibration track 61 and the positive screening track 56 , and the ball 55 is in contact with the blocking block 63 .

[0050] During the extraction process, precipitation is generated, and the precipitation enters the filter holes of the sieve plate 53 and causes blockage. At this time, the movement of the sieve plate 53 is subject to great resistance from the liquid in the extraction tower body 1. When the sieve plate 53 moves downward and moves the ball 55 to the highest point of the positive sieve mixing track 56, the reaction force of the liquid on the sieve plate 53 is greater than the resistance force of the resistance spring 67 and the obstruction block 63 on the ball 55. At this time, the ball 55 presses the obstruction block 63 into the slide groove 66, and the ball 55 enters the vibration track 61. Since the vibration track 61 adopts a sinusoidal wave structure, the ball 55 reciprocates rapidly up and down along the vibration track 61, so that the sieve plate 53 vibrates rapidly, and in the process of the ball 55 moving up and down, the pressure ring 71 collides with the sealing ring 72, further improving the vibration effect to remove the precipitation in the sieve hole.

[0051] like Figure 7 As shown, the upper and lower sides of the obstruction block 63 are respectively provided with an upper inclined surface 65 and a lower inclined surface 64, and the inclination angle of the lower inclined surface 64 is larger than that of the upper inclined surface 65. Due to the existence of the lower inclined surface 64 and the upper inclined surface 65, and the inclination angle of the lower inclined surface 64 is larger than that of the upper inclined surface 65, the ball 55 encounters a large resistance when sliding upward through the lower inclined surface 64, while the ball 55 encounters a small resistance when sliding downward through the upper inclined surface 65, so as to avoid that after the blockage of the sieve holes on the sieve plate 53 is cleared after vibration, the sieve plate 53 encounters a small resistance to liquid movement, and cannot return from the vibration track 61 to the inside of the positive sieve mixing track 56.

[0052] In this embodiment, when the precipitate produced by extraction is blocked in the sieve holes of the sieve plate 53, the resistance to the up and down movement of the sieve plate 53 increases, and the ball 55 moves to the positive screening track 56. At this time, the force of water acting on the sieve plate 53 is greater than the resistance of the obstruction block 63, so that the ball 55 enters the vibration track 61, and the ball 55 vibrates rapidly up and down along the vibration track 61. In the process of the ball 55 moving up and down, the pressure ring 71 collides with the sealing ring 72, thereby further improving the vibration effect and vibrating the precipitate in the sieve holes out.

[0053] Example 2

[0054] Based on Example 1, this example proposes a wastewater dephenolization classification treatment device, such as Figure 4As shown, a reverse screening and mixing track 57 is opened in the middle of the rotating shaft 51, the shape of the positive screening and mixing track 56 is the same as that of the reverse screening and mixing track 57, the placement directions of the positive screening and mixing track 56 and the reverse screening and mixing track 57 are opposite, and two adjacent screening and mixing components slide along the positive screening and mixing track 56 and the reverse screening and mixing track 57 respectively.

[0055] The two adjacent sieve plates 53 slide in the positive sieving and mixing track 56 and the reverse sieving and mixing track 57 respectively. Since the shape of the positive sieving and mixing track 56 is the same as that of the reverse sieving and mixing track 57, and the placement directions of the positive sieving and mixing track 56 and the reverse sieving and mixing track 57 are opposite, the two adjacent sieve plates 53 move in opposite directions. The adjacent sieve plates 53 make the liquid flow in opposite directions, so that the liquid convection occurs in the extraction tower body 1.

[0056] like Figure 2 As shown, the guide notch 54 is slidably connected with the guide bar 58, two guide bars 58 are provided and symmetrically distributed on the inner wall of the extraction tower body 1, the guide bar 58 adopts a fan-shaped structure, and the shape of the guide notch 54 is the same as that of the guide bar 58. The guide bar 58 cooperates with the guide notch 54 to prevent the sieve plate 53 from rotating synchronously when the rotating shaft 51 drives the ball 55 to move by using the positive sieve mixing track 56 and the reverse sieve mixing track 57.

[0057] In this embodiment, two adjacent sieve plates 53 slide in the positive screening and mixing track 56 and the reverse screening and mixing track 57 respectively, and the two adjacent sieve plates 53 move in opposite directions, so that the adjacent sieve plates 53 make the liquid flow in opposite directions, so that the liquid convection in the extraction tower body 1 is accelerated to accelerate the mixing efficiency of the wastewater and the extractant, that is, to improve the dephenolization efficiency.

[0058] Example 3

[0059] Based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a wastewater dephenolization classification treatment device, such as Figure 7 As shown, an anti-infiltration component 7 is provided inside the slide 52, and the anti-infiltration component 7 includes a pressure ring 71, a sealing ring 72 and an airbag 73. The sealing ring 72 is fixedly installed on the inner wall of the slide 52 and close to the end position, the pressure ring 71 is fixedly installed in the middle of the rotating shaft 51 and is located between the two sealing rings 72, and the airbag 73 is fixedly installed between the pressure ring 71 and the sealing ring 72.

[0060] The slide 52 reciprocates up and down to make the pressure ring 71 and the sealing ring 72 continuously stretch and compress the airbag 73, so that the airbag 73 can inhale and eject air to increase the air pressure in the slide 52, thereby preventing the liquid inside the extraction tower body 1 from entering the slide 52 and affecting the sliding of the ball 55.

[0061] An exhaust port 74 is provided at the top of the airbag 73, and the exhaust port 74 is located between the sealing ring 72 and the pressure ring 71. An air suction pipe 75 is provided on the inner wall of the rotating shaft 51, and the air suction pipe 75 extends to the outside of the extraction tower body 1. The bottom of the airbag 73 is connected to the air suction pipe 75. This prevents the airbag 73 from sucking air from the extraction tower body 1 and sucking the liquid inside the extraction tower body 1 into the slide cylinder 52.

[0062] In this embodiment, the air bag 73 is used to increase the air pressure inside the slide 52, and the pressure ring 71 and the sealing ring 72 are used to improve the sealing performance, so as to prevent the liquid inside the extraction tower body 1 from penetrating into the slide 52, causing the vibration clearing member 6 inside the slide 52 to be corroded and unable to operate normally.

[0063] A wastewater dephenolization classification treatment method is applied to the above-mentioned wastewater dephenolization classification treatment device, and the steps are as follows:

[0064] S1, adding extractant: first add extractant from the extractant pipe 2 into the extraction tower body 1, the extractant first forms a relatively stable environment in the tower, then add wastewater from the wastewater pipe 3, the wastewater immediately contacts with the extractant after being added, the extraction process is quickly started, and the extraction efficiency is improved;

[0065] S2, accelerating mixing: the sieve plate 53 fluctuates up and down, and the sieve holes on the sieve plate 53 disperse the extractant and the wastewater into small droplets, thereby increasing the contact area between the wastewater and the extractant. At the same time, the sieve holes on the sieve plate 53 make the liquid flow evenly in the entire extraction tower body 1;

[0066] S3, convection mixing; by making two adjacent sieve plates 53 slide in the positive sieve mixing track 56 and the reverse sieve mixing track 57 respectively, since the positive sieve mixing track 56 and the reverse sieve mixing track 57 are in opposite directions, the movement directions of the two adjacent sieve plates 53 are opposite, and the adjacent sieve plates 53 make the liquid flow in opposite directions, so that the liquid in the extraction tower body 1 is convected to accelerate the mixing efficiency of the wastewater and the extractant, that is, to improve the dephenolization efficiency;

[0067] S4, track change due to sieve hole blockage: precipitation is generated during the extraction process, and the precipitation enters the filter hole of the sieve plate 53 to cause blockage. At this time, the movement of the sieve plate 53 is subject to great resistance from the liquid in the extraction tower body 1. When the sieve plate 53 moves downward and moves the ball 55 to the highest point of the positive sieve mixing track 56, the reaction force of the liquid on the sieve plate 53 is greater than the resistance force of the obstruction block 63 on the ball 55. At this time, the ball 55 presses the obstruction block 63 into the slide groove 66, and the ball 55 enters the vibration track 61;

[0068] S5. Vibration separation: Since the vibration track 61 adopts a sinusoidal structure, the ball 55 reciprocates rapidly up and down along the vibration track 61, so that the sieve plate 53 vibrates rapidly, and in the process of the ball 55 moving up and down, the pressure ring 71 collides with the sealing ring 72, further improving the vibration effect to remove the sediment in the sieve hole.

[0069] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

The inner wall of the rotating shaft (51) is provided with an air intake pipe (75), and the air intake pipe (75) extends to the outside of the extraction tower body (1). The bottom of the air bag (73) is connected to the air intake pipe (75).

10. A wastewater dephenolization classification treatment method, applied to a wastewater dephenolization classification treatment device according to claim 9, the steps of which are as follows: S1, adding an extractant: first, adding an extractant from the extractant pipe (2) into the extraction tower body (1), the extractant first forms a relatively stable environment in the tower, and then adding wastewater from the wastewater pipe (3). After the wastewater is added, it immediately contacts the extractant, and the extraction process is quickly started, thereby improving the extraction efficiency; S2, accelerating mixing: the sieve plate (53) fluctuates up and down, and the sieve holes on the sieve plate (53) disperse the extractant and the wastewater into small droplets, thereby increasing the contact area between the wastewater and the extractant. At the same time, the sieve holes on the sieve plate (53) allow the liquid to flow evenly throughout the extraction tower body (1); S3, convection mixing; by making two adjacent sieve plates (53) slide in the positive sieve mixing track (56) and the reverse sieve mixing track (57) respectively, since the positive sieve mixing track (56) and the reverse sieve mixing track (57) are in opposite directions, the two adjacent sieve plates (53) move in opposite directions, and the adjacent sieve plates (53) make the liquid flow in opposite directions, so that the liquid in the extraction tower body (1) is convected, so as to accelerate the mixing efficiency of the wastewater and the extractant, that is, to improve the dephenolization efficiency; S4, track change due to sieve hole blockage: during the extraction process, precipitation is generated, and the precipitation enters the filter holes of the sieve plate (53) and causes blockage. At this time, the movement of the sieve plate (53) is subject to great resistance from the liquid in the extraction tower body (1). When the sieve plate (53) moves downward and causes the ball (55) to move to the highest point of the positive sieve mixing track (56), the reaction force of the liquid on the sieve plate (53) is greater than the resistance force of the obstruction block (63) on the ball (55). At this time, the ball (55) presses the obstruction block (63) into the slide groove (66), and the ball (55) enters the vibration track (61); S5, vibration separation: Since the vibration track (61) adopts a sinusoidal structure, the ball (55) moves up and down quickly along the vibration track (61), so that the screen plate (53) vibrates quickly, and in the process of the ball (55) moving up and down, the pressure ring (71) collides with the sealing ring (72), further improving the vibration effect, so as to remove the sediment in the screen hole.
