Technical Field

[0001] The present invention belongs to the field of dyeing and bleaching wastewater treatment, and specifically relates to a device and process for treating fabric dyeing and bleaching wastewater. Background Technique

[0002] Fabric dyeing and bleaching wastewater has the characteristics of high chromaticity, high COD (chemical oxygen demand), large pH fluctuation, complex composition, etc. The main pollutants include dyes, auxiliaries, sizing agents, and heavy metal ions, etc. Typical treatment processes need to combine physical and chemical, biochemical, and resource recovery technologies. The specific process is to first perform pretreatment, then biological treatment, followed by advanced treatment, and finally resource recovery. In this process, in the pretreatment stage, the fabric dyeing and bleaching wastewater needs to be filtered first, and then the wastewater is coagulated and precipitated.

[0003] In the existing fabric dyeing and bleaching wastewater pretreatment device, it is easy because the bleaching wastewater contains strongly alkaline mercerizing wastewater and acidic dyeing wastewater. After filtering and mixing these two types of wastewater, the pH value is likely to fluctuate too much, resulting in great difficulty in neutralization and affecting the stability of the biochemical unit, thus affecting the treatment effect of fabric dyeing and bleaching wastewater.

DETAILED DESCRIPTION OF THE INVENTION

[0033] In order to make the technical means, creative features, achieved purposes and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] Embodiment 1:

[0035] As Figures 1 to 7 shown, a fabric bleaching and dyeing wastewater treatment device according to an embodiment of the present invention includes an adjustment tank 1, two treatment tanks 2 communicatively fixed to one side of the top of the adjustment tank 1, a filter barrel 3 disposed on one side of the treatment tank 2, a filter disc 35 disposed inside the filter barrel 3, a top cover 37 threadedly connected to the top of the filter barrel 3, a water delivery pipe 4 communicatively fixed to the bottom of the filter barrel 3, and a neutralization treatment mechanism for treating the wastewater entering the inside of the treatment tank 2. The bottom of the water delivery pipe 4 is communicatively and fixedly arranged with the inner cavity of the adjacent treatment tank 2.

[0036] The neutralization treatment mechanism includes a motor 5 fixed at the middle position between the two treatment tanks 2, a movable shaft 6 rotatably connected to the middle position of the tops of the two treatment tanks 2, belt pulleys 7 fixedly sleeved on the upper and lower ends of the outer peripheral surface of the output end of the motor 5 and the top of the outer peripheral surface of the movable shaft 6, a connecting belt 8 sleeved between the two belt pulleys 7 at the same horizontal height, an aeration assembly disposed inside one of the treatment tanks 2, and a stirring assembly disposed inside the other treatment tank 2.

[0037] Connect the alkaline wastewater to the water inlet pipe of the filter barrel 3 on one side of one of the treatment tanks 2 through a conveying pipeline. Thus, the alkaline wastewater filtered by the filter disc 35 inside the filter barrel 3 flows to the inside of one of the treatment tanks 2 through the water delivery pipe 4. Under the action of the aeration assembly, air is introduced into the alkaline wastewater, and CO2 in the air is dissolved to generate carbonic acid, naturally reducing the pH to the neutral range. Then connect the acidic wastewater to the water inlet pipe of the filter barrel 3 on one side of the other treatment tank 2 through a conveying pipeline. Thus, the alkaline wastewater filtered by the filter disc 35 inside the filter barrel 3 flows to the inside of the other treatment tank 2 through the water delivery pipe 4. When the pH value of the acidic wastewater is less than 5, the stirring assembly can evenly add lime milk to the acidic wastewater while stirring, so that after the acidic wastewater is reduced to between pH 6.5 - 7, the treated alkaline wastewater and acidic wastewater are transported to the inside of the adjustment tank 1 through opening the valve of the pipeline between the adjustment tank 1 and the treatment tank 2 for mixing and precipitation.

[0038] As Figures 1 to 7As shown in the figure, the aeration assembly includes an annular pipe 10 disposed in the inner cavity of one of the treatment tanks 2, a blower 9 fixedly connected to both sides of the annular pipe 10, a plurality of air outlet pipes 14 fixedly connected to the bottom of the annular pipe 10, a stainless steel telescopic hose 15 fixedly connected to the bottom of the air outlet pipe 14, a connecting plate 11 fixed to the bottom of one of the movable shafts 6, a movable seat 13 disposed at the bottom of the connecting plate 11, and a connecting column 12 fixed between the movable seat 13 and the connecting plate 11. The inner wall of the movable seat 13 is fixed to the surface of the stainless steel telescopic hose 15 at an adjacent position, and the surface of the blower 9 is fixed to the outer wall of the treatment tank 2 at an adjacent position;

[0039] The exhaust pipe of the blower 9 is in communication with the inside of the annular pipe 10, and the intake pipe of the blower 9 is placed outside the treatment tank 2. Thus, when the blower 9 is started, the blower 9 can transport external air into the inside of the annular pipe 10, so that the external air can be transported to the inside of the plurality of air outlet pipes 14 through the annular pipe 10. At this time, the water delivery pipe 4 is started, and under the connection action of the pulley 7 and the connecting belt 8, the two movable shafts 6 rotate, so as to drive the connecting plate 11 to rotate. Since the connecting column 12 is not fixed to the middle position at the top of the movable seat 13, the connecting column 12 makes a circular motion around the center point of the movable shaft 6, so that the connecting column 12 drives the movable seat 13 to make a corresponding movement, thereby driving the stainless steel telescopic hose 15 to make a circular motion, so that the external air flowing into the stainless steel telescopic hose 15 through the air outlet pipe 14 can flow in multiple directions, thereby evenly dispersing the air into the alkaline wastewater and improving the contact efficiency between CO and the alkaline wastewater, thus improving the neutralization treatment effect of the alkaline wastewater.

[0040] As Figures 1 to 7 shown in the figure, the stirring assembly includes a fixed seat 16 fixed in the inner cavity of the other treatment tank 2, a plurality of tooth blocks 22 uniformly arranged on the inner peripheral surface of the fixed seat 16, a support plate 20 fixed to the bottom of the other movable shaft 6, a stirring rod 21 rotatably connected to the bottom of the support plate 20, a storage bucket 17 fixed to one side of the support plate 20, a rotating cylinder 23 rotatably connected to the bottom of the storage bucket 17, a conveying component arranged in the inner cavity of the rotating cylinder 23, a sealing component arranged on the top of the storage bucket 17, and a first circular gear 25 fixedly sleeved on the outer peripheral surfaces of the stirring rod 21 and the rotating cylinder 23. The first circular gear 25 is in meshing connection with the plurality of tooth blocks 22, and the inner cavity of the rotating cylinder 23 is in communication with the inner cavity of the storage bucket 17;

[0041] If the pH value of the acidic wastewater entering another treatment tank 2 is less than 5, the position of the storage barrel 17 is adjusted by the cover member, so that lime milk can be added to the inner cavity of the storage barrel 17, and the top of another treatment tank 2 is sealed again by the cover member. When the motor 5 is started, the other movable shaft 6 rotates, so that the support plate 20 rotates. Under the meshing action between the first circular gear 25 and multiple tooth blocks 22, the stirring rod 21 and the rotating cylinder 23 rotate. Thus, during the process that the support plate 20 drives the storage barrel 17 and the rotating cylinder 23 to perform circular motion, lime milk can be discharged downward uniformly through the conveying component, so that the lime milk can be evenly added to the acidic wastewater entering another treatment tank 2, and the stirring rod 21 can rotate while performing circular motion, so as to fully stir the wastewater and lime milk, so that the wastewater and lime milk are mixed more fully, thereby improving the neutralization effect on the acidic wastewater.

[0042] As Figures 1 to 7 shown, the cover member includes an opening 18 penetrating through the top surface of another treatment tank 2 and a sealing cover 19 threadedly connected to the inside of the opening 18;

[0043] By rotating the sealing cover 19, the bottom of the sealing cover 19 is completely disengaged from the inside of the opening 18, so that when the storage barrel 17 is adjusted to directly below the opening 18 by rotating the other movable shaft 6, lime milk can be added to the inside of the storage barrel 17, and the sealing cover 19 is placed on the top of the opening 18 and rotated in the reverse direction, so that the bottom of the sealing cover 19 can be embedded into the inside of the opening 18 for sealing.

[0044] As Figures 1 to 7 shown, the conveying component includes an auger rod 24 inserted into the inner cavity of the rotating cylinder 23, a connecting strip 26 fixed between the inner peripheral surface of the rotating cylinder 23 and both outer peripheral surfaces of the auger rod 24, and a support strip 27 fixed to the inner wall of the storage barrel 17 and arranged in a triangular prism shape. The top of the auger rod 24 is rotatably connected to the surface of the bottom of the support strip 27;

[0045] When the storage barrel 17 performs circular motion along with the support plate 20, the rotating cylinder 23 can be rotated under the meshing action between one of the first circular gears 25 and multiple tooth blocks 22, so that the auger rod 24 rotates under the connection action of the connecting strip 26, and thus the lime milk located in the inner cavity of the storage barrel 17 can be slowly discharged to the outside of the rotating cylinder 23 under the action of the auger rod 24, so that the lime milk can be evenly added from the top of the wastewater along the movement track of the storage barrel 17.

[0046] Embodiment 2:

[0047] In the above - mentioned method, although it solves the problem that when alkaline wastewater and acidic wastewater are directly mixed and precipitated, the pH value is likely to fluctuate too much, resulting in great difficulty in neutralization and affecting the stability of the biochemical unit, thus affecting the treatment effect of fabric bleaching and dyeing wastewater. However, in practice, only filtering through the filter disc 35 in the inner cavity of the filter barrel 3 is likely to cause a certain blockage of the filter disc 35 during long - term use, affecting the rate of transporting alkaline wastewater and acidic wastewater into the treatment tank 2, thereby affecting the neutralization treatment of acidic wastewater and alkaline wastewater.

[0048] As Figures 1 to 7 shown, compared with the first embodiment, another implementation manner of the present invention is as follows:

[0049] It further includes an anti - blocking mechanism acting on the filter disc 35. The anti - blocking mechanism includes a rotating shaft 28 rotatably connected to the top of the treatment tank 2 at a position on one side of the movable shaft 6, a bevel gear 29 fixedly sleeved on the outer peripheral surface of the rotating shaft 28 and on the outer peripheral surface of the movable shaft 6 at a position below the pulley 7, a plurality of abutting shafts 36 uniformly fixed to the bottom inner wall of the filter barrel 3, and a movable assembly fixed to one side of the rotating shaft 28. The bevel gears 29 at two adjacent positions are meshed with each other. The filter disc 35 is slidably connected to the inner cavity of the adjacent filter barrel 3. The plurality of bevel gears 29 correspond one - to - one to the screw holes on the surface of the plurality of filter discs 35;

[0050] When the motor 5 is started to make the movable shaft 6 rotate, the rotating shaft 28 can be made to rotate under the meshing action between the two groups of bevel gears 29. Thus, under the action of the movable assembly, the filter disc 35 can move reciprocally in the vertical direction, so that the filter holes on the surface of the filter disc 35 are repeatedly penetrated by the abutting shafts 36 during the filtering process, thereby preventing debris from blocking the filter holes on the surface of the filter disc 35 and affecting the neutralization treatment of the wastewater.

[0051] As Figures 1 to 7 shown, the movable assembly includes a rotating disc 30 fixed to one side of the rotating shaft 28, a moving plate 31 arranged on one side of the filter barrel 3, a resisting groove 32 opened on one side of the moving plate 31, a resisting rod 33 inserted into the resisting groove 32, guide rods 34 slidably inserted through both ends of the moving plate 31, a fixed shaft 38 slidably inserted through the middle position of the top cover 37, and a threaded rod 39 inserted through the surface of the fixed shaft 38. One side of the resisting rod 33 is fixed to the surface of the rotating disc 30. The bottom of the guide rod 34 is fixed to the surface of the adjacent treatment tank 2. The threaded rod 39 is threadedly connected to the surface of the moving plate 31 away from the resisting groove 32;

[0052] A screw hole matched with the threaded rod 39 is provided on the surface of the moving plate 31 away from the interference groove 32. Before the wastewater is neutralized, the threaded rod 39 is extended through the adjacent fixed shaft 38 to a position close to the adjacent screw hole and the threaded rod 39 is rotated so that the threaded rod 39 is connected to the moving plate 31. After the motor 5 is started, the rotating shaft 28 is rotated, so that the interference rod 33 makes a circular motion. Under the interference between the interference rod 33 and the inner wall of the interference groove 32 and the limiting effect of the guide rod 34 on the moving plate 31, the moving plate 31 can make a reciprocating motion in the vertical direction, so that the screw hole The interference between the threaded rod 39 and the fixed shaft 38 causes the fixed shaft 38 to reciprocate in the vertical direction, thereby driving the filter disc 35 to reciprocate in the vertical direction in the inner cavity of the filter barrel 3 at the adjacent position, so that the filter holes on the surface of the filter disc 35 are repeatedly penetrated by the resistance shaft 36, thereby preventing debris from clogging the filter holes on the surface of the filter disc 35. When the wastewater treatment is stopped, the bolts connecting the top cover 37 to the filter barrel 3 are removed, and the threaded rod 39 is rotated in the reverse direction to separate the threaded rod 39 from the adjacent moving plate 31, so that the top cover 37 can be removed to allow the user to clean the inner cavity of the filter barrel 3 to remove debris.

[0053] like Figure 8 As shown, a fabric bleaching and dyeing wastewater treatment process, the method adopts the above-mentioned fabric bleaching and dyeing wastewater treatment device, and includes the following steps:

[0054] S1: Analyze the pH value of the acidic wastewater to be treated. If the pH value is less than 5, lime milk needs to be added to the storage tank 17. If the pH value is greater than 5, no addition is required.

[0055] S2: By transporting alkaline wastewater and acidic wastewater from 03 to the corresponding interior of 02 and starting 04, the aeration component can neutralize the alkaline wastewater, the stirring component can neutralize the acidic wastewater with a pH value less than 5, and the anti-blocking component works simultaneously to prevent 35 from being blocked;

[0056] S3: After the neutralization treatment of the acidic wastewater and the alkaline wastewater is completed, the valve of the connecting pipe between 02 and 01 is opened to allow the neutralized wastewater to enter the interior of 01 for mixing and precipitation;

[0057] S4: By removing the bolts connecting the top cover 37 and the filter barrel 3, and rotating the threaded rod 39 in the opposite direction to separate the threaded rod 39 from the adjacent moving plate 31, the top cover 37 can be removed so that the user can clean the inner cavity of the filter barrel 3 to remove debris for the next use.

[0058] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1Based on [a certain reference], with the perspective of observing a person as the standard, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

9. A fabric bleaching and dyeing wastewater treatment process, using the fabric bleaching and dyeing wastewater treatment device described in claim 8, characterized in that: It includes the following steps: S1: Analyze the pH value of the acidic wastewater to be treated. If the pH value is less than 5, lime milk needs to be added to the storage tank (17). If the pH value is greater than 5, no addition is required. S2: Transport the alkaline wastewater and the acidic wastewater from 03 to the corresponding 02, and start 04, so that the aeration component can neutralize the alkaline wastewater, the stirring component can neutralize the acidic wastewater with a pH value less than 5, and the anti-clogging component acts synchronously to prevent 35 from being blocked. S3: After the neutralization treatment of the acidic wastewater and the alkaline wastewater is completed, open the valve of the pipeline connecting 02 and 01 so that the neutralized wastewater enters 01 for mixing and precipitation. S4: Remove the bolts connecting the top cover (37) and the filter barrel (3), and reversely rotate the threaded rod (39) so that the threaded rod (39) is separated from the adjacent moving plate (31), so that the top cover (37) can be removed to allow the user to clean the inner cavity of the filter barrel (3) to remove debris for the next use.
