It is one of the difficult-to-treat industrial wastewaters. The wastewater contains dyes, slurries, additives, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc. The main methods used for the treatment of printing and dyeing wastewater are physical and chemical methods, biochemical methods, chemical methods, and treatment methods combining several processes.

Therefore, pretreatment plays an extremely important role in the treatment of printing and dyeing wastewater.

[0003] In the pretreatment process, flocculants are generally used to aggregate and flocculate the suspended matter in the wastewater, thereby reducing the content of impurities in the wastewater. In order to fully mix the flocculant and the wastewater, stirring blades are generally used for stirring. However, there are many fiber impurities and fiber scraps in the textile printing and dyeing wastewater, which are easily entangled on the stirring blades, reducing the mixing effect, and then reducing the flocculation effect.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] 1. Good wastewater treatment effect: A textile printing and dyeing wastewater regeneration treatment equipment and treatment method of the present invention utilizes a filter screen and a movable guide plate to pre-filter larger impurities, flocs and fiber debris in the textile printing and dyeing wastewater. The wastewater entering the wastewater pipe first flows to the net bag, and larger impurities, flocs and fiber debris are blocked in the net bag. The filtered wastewater flows to the bottom of the flocculation tank, where the wastewater is mixed and stirred with the flocculant at the bottom of the flocculation tank to remove fine suspended matter in the wastewater. Since larger impurities, flocs and fiber debris are filtered by the net bag, the occurrence of fiber debris entangled in the stirring blades during the mixing and stirring process is reduced, so that the flocculation effect is better and the effect of textile printing and dyeing wastewater regeneration treatment is improved.

[0021] 2. Convenient treatment: After a period of time, the larger impurities, flocs and fiber scraps in the net bag accumulate, and the driving mechanism moves the top of the movable guide plate to the bottom of the net bag. Then the driving motor 1 and the reducer cooperate to drive the rotating rod to rotate 180°, and the net frame and the net bag also rotate 180°. After the rotation, the wastewater entering the pipe impacts the back of the net bag, flushing away the impurities accumulated on the front of the net bag, and the impurities automatically fall into the movable guide plate below. Finally, the driving mechanism moves the top of the movable guide plate toward the opening, and the inclination angle of the movable guide plate becomes larger, so that the impurities can automatically slide down from the movable guide plate and slide out of the flocculation tank, which is convenient for unified collection and treatment.

[0032] Example 1

[0033] Combination Figures 1 to 6 As shown, a textile printing and dyeing wastewater regeneration treatment equipment according to an embodiment of the present invention is described below.

[0034] Combination Figure 1 and Figure 2As shown, a textile printing and dyeing wastewater regeneration treatment equipment according to an embodiment of the present invention is mainly composed of four parts: a flocculation tank 1, a neutral adjustment tank 2, a hydrolysis acidification treatment tank 3 and an adsorption treatment tank 4. The flocculation tank 1 is used to pre-treat solid impurities and suspended matter in the wastewater, the neutral adjustment tank 2 is used to adjust the pH value of the wastewater, the hydrolysis acidification treatment tank 3 is used to decompose organic matter in the wastewater, and the adsorption treatment tank 4 is used to adsorb odor, discoloration and impurities in the wastewater, thereby further improving the wastewater treatment effect.

[0035] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the flocculation tank 1, the neutral adjustment tank 2, the hydrolysis acidification treatment tank 3 and the adsorption treatment tank 4 are sequentially installed and arranged from right to left, and the flocculation tank 1, the neutral adjustment tank 2, the hydrolysis acidification treatment tank 3 and the adsorption treatment tank 4 are fixed by assembling and welding a steel frame to form a frame. The flocculation tank 1 is divided into two parts, the upper part of the flocculation tank 1 is in the shape of a square box, and the lower part of the flocculation tank 1 is a collecting bucket 104. The bottom of the collecting bucket 104 is connected to a sewage pipe 105, which is convenient for discharging muddy impurities after flocculation, and is more convenient to use.

[0036] Further, such as Figure 1 and Figure 2 As shown, the upper part of the flocculation tank 1 is connected with a pipeline, which extends to the left side. The pipeline is connected with three water inlet pipes and three water outlet pipes. The three water inlet pipes are respectively connected to the tank tops of the neutral adjustment tank 2, the hydrolysis acidification treatment tank 3, and the adsorption treatment tank 4, and the three water outlet pipes are respectively connected to the tank bottoms of the neutral adjustment tank 2, the hydrolysis acidification treatment tank 3, and the adsorption treatment tank 4. The upper clear liquid after the flocculation treatment in the flocculation tank 1 is extracted by the pump on the pipeline, and first enters the neutral adjustment tank 2, then enters the hydrolysis acidification treatment tank 3 after coming out of the neutral adjustment tank 2, then enters the adsorption treatment tank 4 after coming out of the hydrolysis acidification treatment tank 3, and finally is discharged from the adsorption treatment tank 4.

[0037] In some implementations of this embodiment, Figure 3 As shown, a wastewater inlet pipe 5, a driving motor 6 and a filter screen 7 are installed in the flocculation tank 1, and the wastewater inlet pipe 5, the driving motor 6 and the filter screen 7 are all arranged in pairs and symmetrically.

[0038] Combination Figure 3 As shown, the wastewater inlet pipe 5 horizontally passes through the side wall of the flocculation tank 1 and extends into the interior of the flocculation tank 1. A horizontal mounting platform 101 is welded and fixed on the inner wall of the flocculation tank 1, and the drive motor 16 and the reducer 601 are fixedly mounted on the mounting platform 101. The main shaft of the drive motor 16 is connected to the input shaft of the reducer 601, and the output shaft of the reducer 601 is fixedly connected to the rotating rod 602. The rotating rod 602 is supported and fixed by a bearing seat, and the rotating rod 602 maintains an inclination angle of 30°-60°, preferably 45°, and the corresponding filter screen 7 also maintains an inclination of 45°.

[0039] Further, combined with Figure 3 As shown, the filter screen 7 includes a mesh frame 701 and a mesh bag 702. The mesh frame 701 is a metal ring, fixed to the edge of the mesh bag 702, the bottom of the mesh frame 701 is fixedly connected to the top of the rotating rod 602, and the two mesh bags 702 are respectively aligned with the two wastewater inlet pipes 5, and the fluid (wastewater) ejected from the wastewater inlet pipe 5 can fall into the center of the mesh bag 702. After the driving motor 6 is working, it can drive the mesh frame 701 fixed to the mesh bag 702 to rotate 180 degrees, so as to facilitate the separation of the impurity group.

[0040] It should be noted that the net bag 702 is configured as a soft net bag, for example, the net bag 702 is woven from plastic filaments or metal soft wires, which can hold more impurities and has a better use effect.

[0041] In order to reduce the force on the rotating rod 602, a horizontal suspension rod 703 is installed on the top of the flocculation tank 1, and the suspension rod 703 is connected to a vertical suspension rope 704, and the suspension rope 704 is fixedly connected to the top of the net frame 701. The suspension rope 704 shares part of the weight of the net frame 701 and the net bag 702, as well as part of the impact force of the fluid, to extend the service life of the rotating rod 602. In order to better allow the impurities in the net bag 702 to fall, a motor 705 is fixedly installed at the top middle position of the suspension rod 703, and an eccentric wheel is installed on the rotating shaft of the motor 705. After the motor 705 drives the eccentric wheel to rotate, the motor 705 itself vibrates, and the vibration is transmitted along the suspension rod 703 and the suspension rope 704, causing the net bag 702 to vibrate. The vibration of the net bag 702 is conducive to the impurities inside falling after the net bag 702 is turned over.

[0042] In some implementations of this embodiment, Figure 3 As shown, a movable guide plate 8 is installed inside the flocculation tank 1 to facilitate the regular collection of impurity clumps accumulated in the net bag 702. Figure 5 As shown, the main body of the movable guide plate 8 is in the shape of a groove surrounded by three plates, including a bottom plate at the bottom and side plates at both sides. And cylindrical plug rods 801 are installed on both sides of the top of the movable guide plate 8.

[0043] Further, combined with Figure 3 and Figure 4 As shown, horizontal strip grooves 102 are provided on the front and rear sides of the flocculation tank 1, and two insertion rods 801 of the movable guide plate 8 are respectively inserted into the strip grooves 102 on both sides. An opening 103 is provided on the left side wall of the flocculation tank 1, and the lower end of the movable guide plate 8 extends out of the flocculation tank 1 from the opening 103.

[0044] Furthermore, combined Figure 3 and Figure 4As shown, a driving mechanism 9 is used to drive the insertion rod 801 to slide left and right in the strip groove 102. The driving mechanism 9 includes three parts: a driving motor 2, a rotating wheel 901, and a transmission chain 902. A driving motor 2 and two rotating wheels 901 are installed on the outer wall of the flocculation tank 1, and the driving motor 2 and one of the rotating wheels 901 are connected by belt transmission. The transmission chain 902 is sleeved on the two rotating wheels 901, and the bottom of the transmission chain 902 is located on the upper side of the strip groove 102 and is parallel to the strip groove 102. The transmission chain 902 and the strip groove 102 are fixedly connected by a connecting rod.

[0045] It should be noted that two drive mechanisms 9 can be installed to facilitate synchronously driving the two insertion rods 801 to move.

[0046] Combination Figure 6 As shown in FIG. 1 (the arrow indicates the direction of movement of the fluid or impurity group), when the wastewater enters the pipe 5, it first flows to the net bag 702, and the larger impurities, flocs and fiber debris are blocked in the net bag 702. Figure 6 The net bag 702 and wastewater inlet pipe 5 on the upper side are shown. After a period of time, the large impurities, flocs and fiber scraps in the net bag 702 accumulate and need to be cleaned, otherwise it will affect the wastewater filtration. The driving motor 2 drives the rotating wheel 901, and the rotating wheel 901 drives the transmission chain 902 to rotate counterclockwise, and the insertion rod 801 moves to the right along the strip groove 102, so that the driving mechanism 9 moves the top of the movable guide plate 8 to the bottom of the net bag 702 to facilitate catching the fallen impurity groups. Then the driving motor 1 6 and the reducer 601 cooperate to drive the rotating rod 602 to rotate 180°, and the net frame 701 and the net bag 702 also rotate 180°. At this time, Figure 6 As shown in the middle net bag 702 and the wastewater inlet pipe 5, the wastewater in the wastewater inlet pipe 5 after rotation impacts the back of the net bag 702, flushing away the impurities accumulated on the front of the net bag 702. Figure 6 As shown in the net bag 702 and the wastewater inlet pipe 5 at the lower side, the impurity mass automatically falls into the movable guide plate 8 below. Finally, the driving mechanism 9 drives the plunger 801 to move leftward along the strip groove 102, and the inclination angle of the movable guide plate 8 increases, and the impurity mass automatically slides down from the movable guide plate 8 and slides out of the flocculation tank 1 for unified collection.

[0047] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, a flocculant replenishing tank 10 is installed on the right side of the flocculation tank 1, and the flocculant replenishing tank 10 is connected to a replenishing pipe leading to the flocculation tank 1, and the flocculant is sent into the flocculation tank 1 through the replenishing pipe. A stirrer 1001 for stirring the flocculant is also installed on the flocculant replenishing tank 10, and the stirrer 1001 makes the flocculant mixed liquid mix more evenly.

[0048] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, a water pump is installed inside the neutral adjustment tank 2 and the hydrolysis acidification treatment tank 3 as a stirring device, and the water flow sprayed by the water pump accelerates the mixing flow to achieve a stirring effect. An electric heating pipe seat heating device is installed inside the hydrolysis acidification treatment tank 3, and the heating device heats the water to a suitable reaction temperature, and the purification effect is better.

[0049] An activated carbon adsorbent is added into the adsorption treatment tank 4. The activated carbon adsorbent absorbs odor, color and impurities in the wastewater, and has the advantages of low cost and good effect.
