Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and specifically to a wastewater treatment system. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Current technologies typically employ dissolved air flotation (DAF) wastewater treatment equipment. Its working principle involves first using a flocculant in a reaction tank to aggregate impurities in the wastewater into flocs. Then, air or other gases are injected into the DAF tank, generating numerous microbubbles. These bubbles adsorb suspended solids, grease, and other impurities that are difficult to remove by natural sedimentation or flotation, causing them to float to the surface, thus achieving solid-liquid separation. However, in existing technologies, the flocculant is usually added all at once without stirring, resulting in excessive flocculant aggregation. This makes it difficult for the flocculant and wastewater to mix thoroughly, leading to poor flocculation in the reaction tank. Utility Model Content

[0024] The wastewater treatment system of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 and Figure 2As shown, the wastewater treatment system provided by this utility model includes: a tank body 10, a stirring mechanism 20, and a guiding assembly 30. The tank body 10 has a reaction tank 11 and an air flotation tank 12, which are interconnected. The stirring mechanism 20 is rotatably disposed in the reaction tank 11 and includes multiple reaction blades 21. The multiple reaction blades 21 are configured to release flocculant into the reaction tank 11 along their rotation direction when rotating. The guiding assembly 30 is disposed in the reaction tank 11 and located above the reaction blades 21 to guide the flocculant into the reaction blades 21 via the guiding assembly 30.

[0026] In this process, wastewater can first be injected into the reaction tank 11, where flocculants can be used to aggregate impurities in the wastewater into flocs. The flocculants are usually in powder form. Air or other gases are injected into the flotation tank 12 to generate a large number of tiny bubbles. These bubbles are used to adsorb suspended solids, grease and other impurities in the water that are difficult to remove by natural sedimentation or floating, causing them to float on the water surface, thereby achieving solid-liquid separation.

[0027] Reference Figure 2 , Figure 3 and Figure 5 As shown, the stirring mechanism 20 includes: a support frame 22, a motor 23, a stirring shaft 24, and stirring blades 25. The support frame 22 is mounted on the tank body 10; the motor 23 is mounted on the support frame 22; the stirring shaft 24 is connected to the motor 23 and rotatably extends into the reaction tank 11, allowing the motor 23 to drive the stirring shaft 24 to rotate; and the reaction blades 25 are mounted on the circumference of the stirring shaft 24, so that when the motor 23 drives the stirring shaft 24 to rotate, the reaction blades 25 can rotate together with the stirring shaft 24. The flocculant entering the reaction fan blade 21 is dispersed in the reaction tank 11 as the reaction fan blade 21 rotates. The stirring blade 25 is located on the circumference of the stirring shaft 24 and below the reaction fan blade 21. When the stirring shaft 24 rotates, it can drive the stirring blade 25 to rotate in the reaction tank 11, so that the sewage in the reaction tank 11 is stirred and mixed by the stirring blade 25. Combined with the reaction fan blade 21, the flocculant is stirred and dispersed synchronously, so that the sewage in the reaction tank 11 can be fully mixed with the flocculant, thereby improving the flocculation effect.

[0028] Furthermore, the reaction fan blade 21 has a receiving groove, and the side of the receiving groove has a through hole 211, which connects the receiving groove to the reaction tank 11; optionally, the reaction fan blade 21 has a fan-shaped structure, and the through hole 211 is located on the radial side of the reaction fan blade 21.

[0029] In this embodiment, through holes 211 are provided on both radial sides of the reaction fan blade 21, so that the through holes 211 can form convection along the rotation direction of the reaction fan blade 21. When the reaction fan blade 21 rotates, the flocculant in the receiving tank can flow out through the through holes 211 into the reaction tank 11. This can prevent the flocculant from being completely poured into the reaction tank 11 at once, and ensure that the flocculant can be continuously released through the through holes 211, thereby improving its flocculation effect.

[0030] Reference Figure 2 and Figure 4 As shown, the guiding component 30 includes a dispensing seat and a guiding slot 31. The dispensing seat is located below the support frame 22, and flocculant can be dispensed onto the dispensing seat manually or by other means. Since the guiding slot 31 is opened on the dispensing seat and is located above the reaction fan blade 21, the flocculant can be guided through the guiding slot 31 into the receiving groove of the reaction fan blade 21. As a preferred embodiment, the top of the dispensing seat can be configured as a trapezoidal structure that gradually narrows from top to bottom, so that when the poured flocculant is poured onto the dispensing seat, it can be guided to the guiding slot 31. 1. It is understood that the guide slot 31 has a guide inlet 311 and a guide outlet 312. The guide inlet 311 to the guide outlet 312 is constructed as a gradually narrowing conical structure, so that when the flocculant flows from the guide inlet 311 to the guide outlet 312, the amount of flocculant in the guide inlet 311 is always greater than the amount of flocculant in the guide outlet 312. This allows the pressure in the guide inlet 311 to be greater than the pressure in the guide outlet 312, so that the flocculant can continuously flow from the guide inlet 311 to the guide outlet 312, reducing the number of manual operation steps.

[0031] Optionally, the guide outlet 312 is configured as a semi-fan-shaped structure, and the area of ​​the guide outlet 312 is smaller than the area of ​​the reaction fan blade 21, so that when the reaction fan blade 21 rotates, the flocculant flowing out from the guide outlet 312 can accurately flow into the receiving tank of the reaction fan blade 21, so as to ensure that the flocculant can be fully utilized.

[0032] Specifically, there are at least six reaction fan blades 21, which are arranged sequentially at intervals around the axis of the stirring shaft 24; furthermore, there are at least three guide outlets 312, and the at least six reaction fan blades 21 are used to rotate sequentially to the area below the at least three guide outlets 312 during rotation, so that when each guide outlet 312 flows out flocculant into the reaction tank 11, the flocculant flowing out can be received sequentially by each reaction fan blade 21, ensuring a higher utilization rate of flocculant.

[0033] Preferably, the support frame 22 is also provided with a dispensing port 221 coaxially arranged with the guide slot 31, and the diameter of the dispensing port 221 is smaller than the diameter of the guide inlet 311. The dispensing port 221 allows for manual or other operations to dispense flocculant onto the dispensing seat, making the dispensing of flocculant simpler.

[0034] The wastewater treatment system provided by this utility model guides the flocculant to the reaction fan blade 21 through the guide component 30, so that the reaction fan blade 21 can release the flocculant in the reaction tank 11 along its rotation direction when rotating, so that the flocculant can be fully stirred and dispersed in the reaction tank 11 by the reaction fan blade 21, avoiding excessive flocculant agglomeration, and allowing the flocculant and wastewater to be fully mixed, thereby improving the flocculation effect in the reaction tank 11.
