Printing and dyeing wastewater contains a variety of components, including dyes, slurries, auxiliaries, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc. Printing and dyeing wastewater recycling treatment equipment is one of the important equipment for printing and dyeing enterprises to achieve wastewater recycling and meet discharge standards.

[0003] In the prior art, for example, the invention patent disclosed in the publication number CN109354291B is a printing and dyeing wastewater treatment device, which relates to the technical field of wastewater treatment. The present invention includes a water inlet device, a filtering device, an anaerobic biological treatment device and a photocatalytic device. The water inlet device includes a group of first water pipes, three second water pipes are fixedly connected between the two first water pipes, a third water pipe is fixedly connected to one first water pipe, and a fourth water pipe is fixedly connected to the other first water pipe. The filtering device includes a first tank body, a blower and a second motor, and a first fixed plate is fixed to the inner wall of the first tank body. The present invention uses a blower to send external air into the first tank body along a plurality of first slots on the airbag, thereby achieving stirring of the wastewater, and cooperates with the first motor to drive a plurality of fan blades to rotate slowly, so that the wastewater in the first tank body is stirred more fully, and then the oil agent is easily floated up and flows out along the oil drain pipe, and the stirring process is conducive to the adjustment of acid and alkali, so that the acid and alkali adjustment treatment effect in the wastewater is better;

[0004] Although the above equipment can treat printing and dyeing wastewater, it only filters solid and semi-solid wastewater through normal gravity and filter plates, and the filtration cleanliness is insufficient.

[0005] Another example is the invention patent disclosed in the publication number CN114751554B, which is a wastewater treatment device for printing and dyeing wastewater, including a bottom plate and a support ring, the support ring is fixedly arranged on the bottom plate; a treatment box, fixedly arranged in the support ring and provided with discharge ports on both sides, the two sides of the treatment box are respectively connected to a water inlet pipe and a water outlet pipe; a separation mechanism, installed in the treatment box, the printing and dyeing wastewater can be separated into solids and liquids through the separation mechanism; a sedimentation mechanism, fixedly arranged in the treatment box and arranged on one side of the separation mechanism, the sedimentation mechanism is fixedly provided with an opening and closing stirring mechanism, a power output end of the opening and closing stirring mechanism and the sedimentation mechanism are arranged in coordination. The wastewater treatment device for printing and dyeing wastewater provided by the present invention can first separate solid pollutants from liquids by setting a separation mechanism, and then can realize the reciprocating opening and closing of the sedimentation chamber while stirring the wastewater and the precipitant by setting an opening and closing stirring mechanism. It is simple to use and highly practical.

[0006] Although the above-mentioned wastewater treatment equipment can separate the solid and liquid of printing and dyeing wastewater, it is not convenient to simultaneously treat other harmful substances in the printing and dyeing wastewater, and its cleanliness and efficiency in separating objects in the printing and dyeing wastewater are insufficient.

At the same time, various wastewater treatment agents, such as flocculants or regulators, can be synchronously introduced into the mixing box 8, thereby facilitating the subsequent comprehensive treatment of printing and dyeing wastewater. Figure 3 and Figure 4 , the staff can connect the printing and dyeing wastewater discharge pipe with the discharge pipe 35 to facilitate the discharge of the treated wastewater and facilitate further treatment;

[0063] like Figure 1 、 Figure 4 and Figure 12 When performing preliminary treatment on the printing and dyeing wastewater, the staff can start the servo motor 10. At this time, the servo motor 10 can drive the transmission card shaft 1 to rotate. At the same time, the transmission card shaft 1 can synchronously drive the guide turntable 625, the transmission turntable 626, the guide gear 66 and the sealing turntable 36 at the bottom to rotate. When the above-mentioned transmission card shaft 1 rotates, the transmission card shaft 1 can drive the multiple groups of mixing blades 9 on the side to fully mix the printing and dyeing wastewater and various treatment agents inside the mixing box 8, thereby treating and neutralizing various harmful substances in the wastewater, and thus completing the preliminary treatment of the printing and dyeing wastewater;

[0064] like Figure 12 and Figure 14 , the staff can carry out equal treatment of different volumes of different types of printing and dyeing wastewater. When adjusting the volume of wastewater discharged from the wastewater storage tank 63, the staff can start the reduction motor 624. The reduction motor 624 can drive the ball slide 622 to move back and forth inside the guide turntable 625 through the ball screw 623. By adjusting the distance between the ball slide 622 and the fixed slide shaft 621 and the center of the guide turntable 625, the offset distance of the fixed slide shaft 621 driving the liquid guide sealing push plate 627 to move cyclically through the guide rail 628 is adjusted, thereby adjusting the volume of printing and dyeing wastewater discharged equally from the wastewater storage tank 63;

[0065] like Figure 2 、 Figure 12 、 Figure 13 and Figure 14 , when the above-mentioned wastewater is subjected to the same amount of deep treatment, if Figure 14The above-mentioned transmission card shaft 1 can synchronously drive the guide turntable 625 at the bottom to rotate, and the guide turntable 625 can synchronously drive the transmission turntable 626 at the bottom to rotate through the internal ball slide 622 and the fixed slide 621. At the same time, when the fixed slide 621 rotates circumferentially under the drive of the guide turntable 625 and the transmission turntable 626, the fixed slide 621 can pass through the sliding limit with the guide slide 628, and then synchronously drive the guide slide 628 to move sideways in a cycle, so that the guide slide 628 can synchronously drive the liquid guide sealing push plates 627 on both sides to move in a cycle inside the wastewater storage tank 63. In the initial state, the fixed slide 621 is located at the limit of one side. At this time, the liquid guide sealing push plate 627 on this side is located inside the wastewater storage tank 63 near the second one-way liquid guide valve 64. When the liquid guide sealing push plate 627 is moved toward the other side under the drive of the guide slide 628, as shown in FIG. Figure 2 and Figure 13 At this time, negative pressure is generated inside the wastewater storage tank 63 on this side, the first one-way liquid guide valve 2 located at the input end of the wastewater diversion pipe 7 on the same side is opened, and the second one-way liquid guide valve 64 on this side is closed, so that the printing and dyeing wastewater that has been preliminarily treated inside the mixing box 8 can be introduced into the wastewater storage tank 63 along the wastewater diversion pipe 7. When the liquid guide sealing push plate 627 on this side is reset again, the inside of the wastewater storage tank 63 is in a high-pressure state. At this time, the first one-way liquid guide valve 2 is closed, and the second one-way liquid guide valve 64 is opened, so that the printing and dyeing wastewater inside the wastewater storage tank 63 can be introduced into the wastewater treatment tank 54 in equal amounts through the fixed conduit 535;

[0066] like Figure 1 、 Figure 8 and Figure 9 When the liquid-guiding sealing push plate 627 guides the printing and dyeing wastewater from the wastewater storage tank 63, the printing and dyeing wastewater is sequentially introduced into the sealing card seat 531 through the fixed guide pipe 535, and then filtered layer by layer through the filter press plate 532 inside the sealing card seat 531, and finally introduced into the wastewater treatment tank 54. Since there are multiple reagents mixed with the printing and dyeing wastewater in the mixing box 8, various flocculent objects and large particles will be generated. The multi-layer filter press plate 532 can fully filter out various impurities under high hydraulic pressure, thereby improving the wastewater treatment efficiency.

[0067] like Figure 3 、 Figure 8 and Figure 9 When the wastewater storage tank 63 on this side introduces the printing and dyeing wastewater into the wastewater treatment tank 54, the wastewater treatment tank 54 can discharge the previous set of wastewater through the liquid outlet pipe 55. When the above wastewater is introduced into the wastewater treatment tank 54, as shown in FIG. Figure 13The above-mentioned circularly rotating 526 can synchronously drive the guide gear 66 at the bottom to rotate, and the guide gear 66 can synchronously drive the six groups of transmission gears 52 on the side to rotate synchronously, so that the transmission gear 52 can drive the filter adsorption plate 51 at the bottom to rotate inside the wastewater treatment tank 54, thereby adsorbing harmful substances in the printing and dyeing wastewater after the filter press treatment. At the same time, the printing and dyeing wastewater inside the three groups of wastewater treatment tanks 54 on both sides is alternately transported, which can provide sufficient time for wastewater treatment;

[0068] like Figure 2 、 Figure 4 and Figure 5 The treated wastewater is introduced into the collection box 33 through the liquid outlet conduit 55 and the sealing groove 32. At this time, when the guide gear 66 rotates, it can drive the sealing rotary seat 36 and the wastewater centrifugal drum 37 to rotate through the transmission shaft 65, so that the wastewater inside the wastewater centrifugal drum 37 can be centrifuged against the side wall. Since the sealing rotary seat 36 is rotatably connected to the collection box 33, the wastewater introduced into the collection box 33 is introduced into the wastewater centrifugal drum 37 through the liquid inlet guide groove 311 inside the sealing rotary seat 36. With the high-speed centrifugation of the wastewater centrifugal drum 37, due to the different densities and masses of various impurities in the wastewater, the impurities of various printing and dyeing wastewater are concentrated at the bottom and middle of the sealing bottom cover 38. The upper layer of centrifuged clear liquid is introduced into the wastewater collecting drum 34 through the drainage groove 39. The wastewater collecting drum 34 can discharge the centrifuged printing and dyeing wastewater through multiple sets of discharge conduits 35.
