Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a flocculation wastewater treatment device. Background Technology

[0002] Flocculation wastewater treatment refers to the process of adding flocculants to cause suspended particles and colloidal substances in wastewater to aggregate into larger flocs, which are then easily separated and removed by methods such as sedimentation and filtration. However, the traditional method of adding flocculants involves directly adding them into the flocculation tank all at once, resulting in uneven distribution of the flocculants in the wastewater and incomplete mixing between the flocculants and the wastewater.

[0003] To address this, patent 2022211487020 discloses a dosing device for wastewater flocculation, which integrates spray nozzles onto a stirring rod to achieve uniform mixing and distribution of the flocculant. However, as flocculation progresses, the spray nozzles are prone to clogging, requiring regular cleaning of the stirring rod. However, the stirring rod in the aforementioned patent is not easily disassembled, making it difficult to remove the stirring rod from the flocculation reaction tank for cleaning. Summary of the Invention

[0004] The main purpose of this utility model is to provide a flocculation wastewater treatment device. By setting the dosing hole on the stirring rod, the flocculant and wastewater are mixed evenly. At the same time, the stirring rod can be quickly disassembled and removed from the flocculation reaction tank for cleaning.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] See Figure 1 and Figure 2A flocculation wastewater treatment device includes a flocculation reaction tank 1 and a dosing assembly 2. A support beam 3 is provided above the top of the flocculation reaction tank 1. A horizontal turntable 4 and a motor 5 for driving the horizontal turntable 4 to rotate are provided on the support beam 3. A plurality of sinkholes 18 for suspending and installing stirring rods 6 are evenly distributed on the horizontal turntable 4. The upper end of the stirring rod 6 is provided with a hook 7, which is an annular boss adapted to the large diameter end of the sinkhole 18. The stirring rod 6 is inserted into the flocculation reaction tank 1 after passing through the sinkhole 18. The hook 7 is locked in the large diameter end of the sinkhole. A dosing channel 8 is provided inside the stirring rod 6. A plurality of dosing holes 9 communicating with the dosing channel 8 are evenly distributed on the rod section of the stirring rod 6 inserted into the flocculation reaction tank 1. The dosing assembly 2 is provided on the horizontal turntable 4 and is configured to deliver flocculant into the dosing channel 8.

[0021] In this embodiment, by setting the dosing hole 9 on the stirring rod 6, the motor 5 drives the horizontal turntable 4 to rotate slowly, which realizes the uniform mixing and distribution of flocculant. Moreover, the stirring rod 6 is suspended on the horizontal turntable 4 by the hook 7. When it is necessary to clean the stirring rod 6, it is only necessary to pull the stirring rod 6 out of the horizontal turntable 4. The stirring rod 6 is very convenient to install and remove.

[0022] See Figure 1 Specifically, the flocculation reaction tank 1 has an inlet 10 at the bottom side and an outlet 11 at the top side. The bottom of the flocculation reaction tank 1 has an inverted conical mud guide trough 17, and the bottom of the inverted conical mud guide trough 17 has a drain valve 12. The dosing assembly 2 includes a storage tank 201, a dosing hose 202, and a dosing pump 203. One end of the dosing hose 202 is connected to the storage tank 201, and the other end is connected to the dosing channel 8. The dosing pump 203 is installed on the dosing hose 202.

[0023] When the above-mentioned flocculation wastewater treatment device is working, the wastewater enters the flocculation reaction tank 1 through the inlet 10. The flocculant in the storage tank 201 flows through the dosing hose 202 and the dosing channel 8 under the pressure of the dosing pump 203, and finally sprays out from the dosing hole 9 into the flocculation reaction tank 1. The suspended particles and colloidal substances in the wastewater undergo flocculation reaction under the action of the flocculant, agglomerate into larger flocs, and settle and accumulate in the inverted cone-shaped sludge guide trough. Finally, they are discharged outside the reaction tank through the sludge discharge valve. The wastewater after flocculation treatment flows out from the outlet 11 at the top of the reaction tank.

[0024] See Figure 1It is understandable that the dosing hose 202 is divided into a main dosing pipe and a branch dosing pipe connected to the main dosing pipe. The dosing pump 203 is installed on the main dosing pipe. Each branch dosing pipe is connected to the corresponding stirring rod 6 through a quick-release connector. The quick-release connector is a threaded connector 13. The top of the dosing channel 8 is provided with an internal thread, and the threaded connector 13 is provided with an external thread. One end of the threaded connector 13 is fixedly connected to the branch dosing pipe, and the other end is screwed and fixed on the internal thread.

[0025] In this embodiment, when it is necessary to remove the stirring rod 6 from the reaction tank for cleaning, simply unscrew the threaded connector 13 from the stirring rod 6, then hold the hook 7 and pull the stirring rod 6 out from the top of the horizontal turntable 4, and then soak the removed stirring rod 6 in the cleaning agent for cleaning.

[0026] See Figure 1 In some embodiments, an annular aeration disc 14 is provided below the stirring rod 6 in the flocculation reaction tank 1. The annular aeration disc 14 is connected to the external ozone generator 15 through a pipe. A number of aeration holes 16 are evenly distributed on the inner and outer walls of the annular aeration disc 14.

[0027] In this embodiment, ozone is introduced into the wastewater in the reaction tank through the annular aeration disc 14, which decomposes the recalcitrant organic matter in the wastewater into smaller organic molecules, improving the biodegradability of the wastewater and further enhancing the purification effect. Furthermore, the aeration holes 16 are located on the side of the annular aeration disc 14, making them less prone to clogging.
