[0002] In modern industrial production, perfluorotributylamine is widely used in electronics, pharmaceuticals, surfactants and other fields as an important chemical raw material. However, the wastewater produced in its production process contains a large amount of organic pollutants, particulate impurities and harmful chemicals. If the wastewater is directly discharged without proper treatment, it will cause serious pollution to the environment and affect the ecological system and human health.

[0003] The traditional treatment method mainly relies on physical filtration purification, which intercepts large particulate impurities in wastewater through a filter screen. However, this method has obvious shortcomings. First, the filter screen is easily clogged by impurities during use, resulting in a significant decrease in filtration efficiency. In order to maintain the normal operation of the equipment, the filter screen needs to be cleaned or replaced frequently, which not only increases the maintenance cost but also prolongs the downtime of the equipment, affecting the production efficiency. Second, the single physical filtration method can only remove large particulate impurities in wastewater, and the removal effect of fine particulate and dissolved pollutants is limited, which is difficult to meet the requirement of deep purification.

[0021] The rotating rod 5 and the transmission rod 15 are both rotationally connected to the inner wall of the sedimentation tank 1, the lower surface of the separation frame 11 is provided with a plurality of screening mesh holes 17, the wastewater filtered through the activated carbon filter screen 12 is further subjected to secondary separation and filtration through the screening mesh holes 17, further removes small-particle impurities.

[0022] The surface of the driven pulley 14 is fixedly connected with the extension rod 18, the extension rod 18 is rotationally connected to the surface of the support table 2.

[0023] The lower surface of the sedimentation tank 1 is fixedly connected with the discharge pipe 19, the inside of the discharge pipe 19 is provided with a valve, the treated wastewater is discharged through the discharge pipe 19, the valve controls the discharge of the wastewater.

[0024] The lower surface of the sedimentation tank 1 is fixedly connected with the support frame 20, the number of the support frame 20 is set to four, the four support frames 20 are respectively fixedly connected to the four corners of the lower surface of the sedimentation tank 1.

[0025] A control panel 21 is provided on the outer surface of the sedimentation tank 1, and the control panel 21 is electrically connected to the drive motor 3.

[0026] Both sides of the inner wall of the sedimentation tank 1 are fixedly connected with guide plates 22. The guide plates 22 are located above the activated carbon filter screen 12. The guide plates 22 guide the wastewater to be evenly distributed and improve the filtration effect of the activated carbon filter screen 12.

[0027] The implementation principle of the wastewater treatment device and method for perfluorotributylamine in this application embodiment is as follows: Wastewater first enters the sedimentation tank 1. The guide plate 22 can effectively guide the wastewater to be evenly distributed, avoiding the wastewater directly impacting the activated carbon filter 12, which could lead to local overload or uneven filtration. The wastewater falls onto the activated carbon filter 12 in the separation frame 11. The activated carbon filter 12, with its porous structure and adsorption performance, pre-treats the wastewater, effectively removing large particulate impurities and some organic pollutants, thus purifying the wastewater. At the same time, the drive motor 3 starts, and the active pulley 4 at its output end rotates accordingly, driving the connected rotating rod 5 and eccentric cam 6 to rotate synchronously. The special structure of the eccentric cam 6 enables it to rotate... During the process, the separation frame 11 is periodically lifted. When the separation frame 11 is lifted, the built-in spring 9 is stretched by the telescopic rod 10 below. When the protruding part of the eccentric cam 6 disengages from below the separation frame 11, the built-in spring 9 quickly returns to its original position, causing the separation frame 11 to vibrate. This effectively prevents the mesh of the activated carbon filter 12 from being clogged by impurities, ensuring its continuous and efficient filtration performance. This ensures that the wastewater can pass smoothly and enter the bottom of the sedimentation tank 1. After being filtered by the activated carbon filter 12, the wastewater continues to pass through these screening meshes 17 for secondary separation and filtration under the action of gravity. The screening meshes 17 can effectively intercept and remove fine particulate impurities, ensuring that the wastewater reaches a higher level of cleanliness before entering the bottom of the sedimentation tank 1.

[0028] Subsequently, personnel add appropriate amounts of chemical agents according to the characteristics and treatment requirements of the wastewater. At this time, the driving pulley 4 drives the driven pulley 14 to rotate through the transmission belt 13, which in turn drives the transmission rod 15 and the mixing blade 16 on it to rotate. The rotation of the mixing blade 16 generates a strong stirring effect, which makes the wastewater that has been preliminarily filtered by the activated carbon filter 12 fully mixed with the chemical agents. The chemical agents can quickly and evenly react with the pollutants in the wastewater, further decompose and remove harmful substances in the wastewater, thereby significantly improving the wastewater treatment effect. The treated wastewater is discharged through the discharge pipe 19, and the valve controls the discharge of the wastewater.
