Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a high-efficiency coagulation and flotation device for treating textile printing and dyeing wastewater. Background Technology

[0002] Textile dyeing and printing wastewater is typically treated using coagulation-flotation (CFDF) devices for filtration. CFDF devices employ the flotation method, which utilizes highly dispersed microbubbles as carriers to adhere to pollutants in the wastewater. This causes the buoyancy to exceed the weight and buoyancy resistance, allowing the pollutants to rise to the surface and form foam. The foam is then scraped off from the surface using a skimmer, achieving solid-liquid or liquid-liquid separation. The necessary conditions for flotation are: a large number of microbubbles should be distributed in the wastewater being treated, ensuring the pollutants are in a suspended state, and the suspended particles should have hydrophobic surfaces to facilitate adhesion to the bubbles and subsequent floating.

[0003] For example, a wastewater treatment device as described in (authorization announcement number CN217377576U) includes a fixed surface, and a conversion tank, a flotation tank, a support, a dissolved air tank, and a pressurizing pump disposed on the fixed surface. The conversion tank is provided with a guide surface, a wastewater inlet pipe, a coagulant inlet pipe, a flocculant inlet pipe, a first water pipe, and a first motor. The first motor is provided with a rotating shaft, and the rotating shaft is provided with a stirring plate. The stirring plate is provided with a mixing hole. The flotation tank is provided with a drain pipe. The support is provided with a sliding seat and a second motor. The sliding seat is provided with a cylinder, and the cylinder is provided with a scraper. The second motor is provided with a screw.

[0031] Please see Figures 1-5 This utility model discloses a high-efficiency coagulation and flotation device for treating textile dyeing and printing wastewater. Compared with Embodiment 1, this embodiment further includes: a stirring and filtering assembly 3, a diversion plate 31 fixedly connected to the lower end of a clarification tank 14, a filter tube 32 whose front end is fixedly connected to the diversion plate 31 and placed at the lower end of the clarification tank 14, and whose rear end passes through a conversion shell 11 and is placed in a slag guide trough 15, a stirring tank 33 fixedly connected to the front end of the conversion shell 11 and placed in the middle of the conversion tank 13, a second motor 34 fixedly connected to the upper end of the conversion shell 11, and a rotating rod 35 whose upper end is rotatably connected to the conversion shell 11. After the second motor 34 is started, it can drive the rotating rod 35 to rotate and drive the stirring fan blades 36 to rotate synchronously to stir and mix the wastewater and the mixing agent. The upper end of the rotating rod 35 is also fixedly connected to the drive shaft at the lower end of the second motor 34. The upper end of the stirring fan blades 36 is fixedly connected to the rotating rod 35 and is placed in the stirring tank 33. The diversion plate 31 is provided in five sets, and the filter tubes 32 are provided in four sets.

[0032] The dissolved air tank assembly 4 has a rear end fixedly connected to a pressurizing pump 45, a water inlet valve pipe 42 fixedly connected to the upper end of the dissolved air tank 41, an air inlet valve pipe 43 also fixedly connected to the upper end of the dissolved air tank 41, an exhaust valve pipe 44 fixedly connected to the top of the dissolved air tank 41, a pressurizing pump 45 fixedly connected to the upper end of the conversion shell 11, and after the pressurizing pump 45 is started, it can integrate air into the water in the dissolved air tank 41 to form dissolved air water. The upper end of the dissolved air delivery pipe 46 is fixedly connected to the dissolved air tank 41, and the dissolved air nozzle 47 is fixedly connected to the lower end of the dissolved air delivery pipe 46. The dissolved air nozzle 47 is fixedly connected between the conversion tank 13 and the clarification tank 14.

[0033] In this embodiment:

[0034] First, when efficient treatment of textile dyeing and printing wastewater is required, the second motor 34 can be started by the display controller 21 when the wastewater enters the conversion tank 13. At the same time, the mixing agent is transported into the conversion tank 13 through the mixing agent conveying pipe 111 to mix with the wastewater. After the second motor 34 starts, it can drive the rotating rod 35 to rotate, which in turn drives the stirring fan blades 36 to rotate synchronously to stir and mix the wastewater and the mixing agent, quickly converting the dissolved organic matter in the oily wastewater into non-dissolved substances, thus improving the filtration efficiency. At the same time, the inlet valve pipe 42, the air inlet valve pipe 43 and the pressurization pump 45 are started. After the inlet valve pipe 42 and the air inlet valve pipe 43 are started, clean water and clean air can be introduced into the dissolved air tank 41. 5. After startup, air can be incorporated into the water in the dissolved air tank 41 to form dissolved air water. Then, the dissolved air water in the dissolved air tank 41 and the dissolved air nozzle 47, which is transported through the dissolved air delivery pipe 46, are sprayed out and mixed with the wastewater after mixing. This allows impurities in the wastewater to quickly float to the upper part of the water surface in the clarification tank 14, while the clarified water can quickly sink in the clarification tank 14. When the clarified water is at the lower end of the clarification tank 14, it can be filtered again by the filter pipe 32 and then transported to the primary filtration water tank 17. The clarified water after the second filtration can be transported to the secondary filtration water tank 18. Since the secondary filtration water tank 18 is higher than the primary filtration water tank 17, heavier impurities in the clarified water can be placed at the lower end of the primary filtration water tank 17 and will not enter the secondary filtration water tank 18, thus increasing the filtration effect. The clarified water in the secondary filtration water tank 18 can be discharged through the drain pipe 19.

[0035] This invention provides an improved, highly efficient coagulation and flotation device for treating textile dyeing wastewater. By incorporating a conversion shell assembly 1 capable of filtering large quantities of wastewater, the device can filter a significant amount of wastewater, resulting in better filtration efficiency.
