DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a wastewater treatment device includes a sedimentation tank body 1, which is connected to a pipe body 2. High-ammonia nitrogen wastewater is introduced into the left side of the pipe body 2, and the high-ammonia nitrogen wastewater is discharged from the right side of the pipe body 2 and enters the sedimentation tank body 1. When the high-ammonia nitrogen wastewater flows through the pipe body 2, a chemical agent is added into the high-ammonia nitrogen wastewater, and the chemical agent is aluminum sulfate or polyaluminum chloride solvent, so that a chemical reaction occurs in the high-ammonia nitrogen wastewater and a precipitate is formed in the sedimentation tank body 1 to treat the ammonia nitrogen in the wastewater.

[0026] like Figure 2 As shown, the pipe body 2 includes a first pipe body 22, a second pipe body 23, and a separator 21. The first pipe body 22 is provided with a first cavity 221, and the second pipe body 23 is provided with a second cavity 231. The first cavity 221 and the second cavity 231 are respectively located on both sides of the separator 21. The separator 21 separates the first cavity 221 and the second cavity 231. The separator 21 is provided with a slot 213, and both sides of the slot 213 are respectively connected with the first cavity 221 and the second cavity 231. The separator 21 is provided with a plug hole 212, and the plug hole 212 extends downward from the upper end of the separator 21, and the bottom of the plug hole 212 extends to the top of the slot 213. A first channel hole 211 is provided on the side of the separator 21 facing the second cavity 231. The left end of the first channel hole 211 is connected to the plug hole 212, and the right end of the first channel hole 211 is connected to the second cavity 231. The chemical agent enters the second cavity 231 through the first channel hole 211 and reacts with the high-ammonia nitrogen wastewater flowing in the second cavity 231.

[0027] like Figure 6 As shown, the first pipe body 22 includes a wall surface 222 at the bottom, and the wall surface 222 is inclined downward along the wastewater flow direction. Figure 7As shown, the bottom of the second pipe body 23 is a horizontal wall. When high-ammonia nitrogen wastewater is introduced into the second cavity 231 , a small amount of high-ammonia nitrogen wastewater will flow into the first cavity 221 through the slot 213 , and flow into the sedimentation tank body 1 depending on the inclination of the wall 222 .

[0028] like Figure 2 , Figure 3 As shown, the partition 21 is installed with an insertion rod 4, which is inserted from the top of the partition 21. The insertion rod 4 includes a rod head 41 located at the top and a rod body 42 located below the rod head 41. The rod body 42 is inserted into the insertion hole 212 and extends into the slot 213. The rod head 41 is located at the upper end of the partition 21 and is fixedly connected to the partition 21. A groove body 411 is provided at the bottom of the rod head 41. The groove body 411 is recessed upward along the bottom of the rod head 41 to form an annular groove body structure. The minimum inner diameter of the groove body 411 is the same as that of the rod body 42.

[0029] like Figure 3 As shown, the insertion rod 4 is provided with a third channel 43, which extends downward from the top of the insertion rod 4. The third channel 43 includes an extension channel 431 located at the bottom, which penetrates the inner wall of the insertion rod 4 to the right, and the extension channel 431 is aligned with the first channel hole 211.

[0030] like Figure 2 , Figure 3 As shown, the rod 4 is installed with a kit 3, which includes a sleeve 31. The sleeve 31 is a cylindrical ring structure. The sleeve 31 is inserted into the rod 42 with clearance fit, and the upper end of the sleeve 31 is inserted into the groove 411. The bottom of the sleeve 31 is threadedly connected with a wheel-shaped component 32, which is combined with Figure 5 The wheel-shaped component 32 includes a plurality of blades 321 located radially outward, some of the blades 321 are located in the first cavity 221, and some of the blades 321 are located in the second cavity 231. When the high-ammonia nitrogen wastewater in the second cavity 231 flows, the blades 321 are driven to rotate, so that the wheel-shaped component 32 drives the entire set 3 to rotate along the axis of the set 3.

[0031] There is a 1 mm-2 mm gap between the top of the sleeve 31 and the upper wall of the groove 411 , and the bottom of the sleeve 31 abuts against the bottom wall of the slot 213 to prevent the sleeve 31 from separating from the wheel-shaped component 32 .

[0032] like Figure 3 As shown, the extension channel 431 is separated from the first channel hole 211 by the sleeve 31, and the sleeve 31 is provided with a second channel 311. Figure 4There are multiple second channels 311 evenly distributed along the circumference of the sleeve 31. When the sleeve 31 rotates, when one axial end of one of the second channels 311 is connected to the extension channel 431, the other axial end of the second channel 311 is connected to the first channel hole 211, so that the first channel hole 211 is connected to the third channel 43. When the second channel 311 is completely staggered with the first channel hole 211 and the third channel 43, the first channel hole 211 is disconnected from the third channel 43.

[0033] A valve body 5 is installed on the top of the rod head 41, and a liquid holding component 6 is installed on the upper end of the valve body 5. Chemical agents are placed in the liquid holding component 6. After the valve body 5 is opened, the chemicals enter the third channel 43. After high-ammonia nitrogen wastewater is introduced into the second cavity 231, the flow of the high-ammonia nitrogen wastewater drives the kit 3 to rotate. As the second channel 311 intermittently connects and disconnects the first channel hole 211 and the third channel 43, the chemicals are intermittently added to the high-ammonia nitrogen wastewater. The faster the high-ammonia nitrogen wastewater flows, the higher the frequency of connection between the first channel hole 211 and the third channel 43, and the higher the frequency of chemical addition, so that the chemicals can be more fully mixed with the high-ammonia nitrogen wastewater, thereby accelerating the reaction efficiency of the chemicals and the high-ammonia nitrogen wastewater, accelerating the completion of the precipitation treatment process, and improving the process efficiency.
