[0002] Flotation and sedimentation are commonly used treatment methods in the current water treatment process. The flotation machine uses microbubbles dissolved in water to attach to suspended solids in the water, so that the suspended solids in the water float on the water surface, thereby achieving the effect of solid-liquid separation; the sedimentation tank uses the gravity sedimentation of the suspended solids themselves after adding water treatment agents to separate mud and water. Publication number: CN202121669509.7, discloses a wastewater treatment flotation device, which relates to the technical field of wastewater treatment, including a tank body, a sewage pipe, a motor, a straight rod and a vertical rod.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 5 As shown, an embodiment of the utility model provides a dual-purpose wastewater treatment device for flotation and sedimentation with water outlet conversion, comprising: a wastewater tank 1, a scum groove 9 is arranged on one side of the wastewater tank 1 for collecting floating scum, an air releaser 5 is arranged in the wastewater tank 1, and an agitator 6 is arranged at one end of the wastewater tank 1 to accelerate the dilution of sludge precipitated from sewage and remove odor; a conversion box 2, a first perforated pipe 10 is arranged at one end of the conversion box 2, a first control valve 13 is arranged on the outer surface of the first perforated pipe 10, a second perforated pipe 3 is arranged on the lower surface of the conversion box 2, a second control valve 12 is arranged on the outer surface of the second perforated pipe 3, and one end of the first perforated pipe 10 and the second perforated pipe 3 are both arranged in the wastewater tank 1; a scum scraping assembly 4, the scum scraping assembly 4 is arranged above the wastewater tank 1, and the scum scraping assembly 4 is arranged corresponding to the scum groove 9; the first perforated pipe 10 is located at the upper end of the wastewater tank 1, and the second perforated pipe 3 is located at the lower end of the wastewater tank 1;

[0034] Specifically, flotation and sedimentation are commonly used treatment methods in current water treatment processes. Figure 1 and Figure 2 The first perforated tube 10 is a flotation perforated tube. The flotation treatment uses microbubbles dissolved in water to attach to suspended solids in the water, so that the suspended solids in the water float on the water surface, thereby achieving the effect of solid-liquid separation. Subsequently, the floating scum is scraped into the scum tank 9 through the scraping component 4 for cleaning. Since the scum is at the top, the sewage is extracted from the bottom; the second perforated tube 3 is a sedimentation perforated tube. The sedimentation treatment is to separate mud and water by the gravity sedimentation of the suspended matter after adding water treatment agents. The sludge is at the bottom, so when extracting, it is extracted from the top.

[0035] The first perforated pipe 10 and the second perforated pipe 3 are respectively provided with a first control valve 13 and a second control valve 12, so that when a failure occurs in the flotation operation, the second control valve 12 is closed, and then the first control valve 13 is started to drain water from the first perforated pipe 10, thereby achieving the effect of changing the water discharge mode of the equipment when one side is damaged, making the wastewater treatment system operate normally, and buying time for repairing and replacing the faulty equipment.

[0036] Furthermore, a water inlet pipe 15 is provided at the other end of the conversion box 2, and the water inlet pipe 15 is provided corresponding to the first perforated pipe 10, and a liquid level regulating valve 14 is provided in the conversion box 2;

[0037] Specifically, refer to Figure 1 The liquid level regulating valve 14 is arranged in the conversion box 2, and an air flotation water outlet pipeline and an air flotation liquid level regulating sleeve are arranged below the liquid level regulating valve 14, and the air flotation water outlet pipeline and the air flotation liquid level regulating sleeve are both installed inside the conversion box 2. When in use, the appropriate height of the liquid level in the air flotation tank body is adjusted by raising or lowering the sleeve height.

[0038] Furthermore, the scraper assembly 4 includes two sets of mounting plates 401, which are correspondingly arranged on the upper surface of the wastewater tank 1, and the two sets of mounting plates 401 brackets are provided with a conveyor belt 402, and two sets of scrapers 405 are arranged on the surface of the conveyor belt 402; multiple sets of rollers 404 are arranged in the conveyor belt 402, and a driving motor 403 is arranged on one side of the mounting plate 401, and the output end of the driving motor 403 is fixedly connected to the roller 404;

[0039] Specifically, refer to Figure 1 and Figure 3 As shown in the accompanying drawings, two groups of scrapers 405 are respectively arranged at the upper end and the lower end of the non-working conveyor belt 402, so that the drive motor 403 is started to drive the roller 404 to rotate, so that the conveyor belt 402 runs, and the scraper 405 below follows the running track of the conveyor belt 402 to slide and scrape off the floating scum in the waste water tank 1. At the same time, when one group of scrapers 405 works for the first time and moves above the conveyor belt 402, the other scraper 405 will work, and they work in sequence to continuously clean the rising scum.

[0040] Furthermore, the scraper 405 includes a fixed box 4051 and a rake 4053. The fixed box 4051 is arranged on the conveyor belt 402. A chute 4052 is provided in the fixed box 4051. Slide blocks 4054 are fixedly installed at both ends of the rake 4053. The slide blocks 4054 are slidably installed in the chute 4052. A pad 11 is fixedly installed between the scum trough 9 and the waste water tank 1. The pad 11 is arranged in an oblique line. The pad 11 is arranged corresponding to the rake 4053.

[0041] Specifically, the pad 11 can prevent the scum and sewage from flowing into the scum tank 9 together. Figure 2 and Figure 4 As shown, the top of the rake blade 4053 is an arc-shaped section, so that when the rake blade 4053 moves to the pad 11, the bottom of the rake blade 4053 is subjected to force, and through the cooperation of the slider 4054 and the slide groove 4052, the rake blade 4053 will slowly retract into the fixed box 4051 along the inclined surface of the pad 11, thereby achieving the effect of not affecting normal operation.

[0042] Further, such as Figure 1 A mud collecting bucket 7 is detachably mounted on the lower surface of the wastewater tank 1, and a mud discharge valve 8 is fixedly mounted on one end of the mud collecting bucket 7;

[0043] Specifically, when in use, the inclination of the mud collecting bucket 7 can be increased so that the mud can be discharged more smoothly when the air flotation and sedimentation device is operated in the sedimentation tank discharge mode.
