Description

Technical Field

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

[0002] In the wastewater treatment process, the addition of chemicals (such as flocculants, oxidants, pH adjusters, etc.) is a critical step. In actual production, chemicals are usually added manually. However, the amount and quality of wastewater fluctuate during the treatment process. Manual addition based on experience is costly and has a delayed response time, requiring 30-60 minutes to respond, making timely adjustments impossible and resulting in a large amount of substandard wastewater being generated. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive dosing device for wastewater treatment agents to solve the problem of long response time in existing wastewater treatment equipment dosing methods.

[0004] This utility model provides a wastewater chemical adaptive dosing device, including a flocculation tank, an anaerobic tank, a biological filtration tank, and a clear water tank. It also includes a dosing assembly located at the upper end of the flocculation tank. The dosing assembly includes an effluent regulating tank, a linkage component located at the outlet end of the effluent regulating tank, a chemical tank switch connected to the end of the linkage component, and a chemical tank connected to the chemical tank switch.

The upper end of the baffle plate is rotatably connected to the effluent regulating tank, and the right side of the baffle plate is fixedly connected to the linkage component.

[0005] The aforementioned wastewater chemical adaptive dosing device works by continuously impacting a baffle plate as wastewater flows into the effluent regulating tank. This impact causes the baffle plate to move to the right, thereby pressing the chemical tank switch. The greater the water flow, the greater the impact on the baffle plate, and the greater the amount of chemicals dispensed from the chemical tank switch. This allows for automatic adjustment of the chemical dispensing amount based on the volume of wastewater, resulting in a timely response.

[0006] Furthermore, the linkage component is a linkage rod.

[0007] Furthermore, it also includes a basket-type grille, which is located inside the water outlet regulating tank.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figures 1 to 3This utility model provides a wastewater chemical adaptive dosing device, including a flocculation tank 10, an anaerobic tank 20, a biological filter tank 30, and a clear water tank 40. It also includes a dosing assembly 50 located at the upper end of the flocculation tank 10. The dosing assembly 50 includes an effluent regulating tank 51, a linkage 52 located at the effluent outlet of the effluent regulating tank 51, a medicine tank switch 53 connected to the end of the linkage 52, and a medicine tank 54 connected to the medicine tank switch 53. The medicine tank 54 contains chemical solution. The effluent regulating tank 51 has an outlet on its right side. A baffle 55 is rotatably connected to the opening of the outlet. The upper end of the baffle 55 is rotatably connected to the effluent regulating tank 51, and the right side of the baffle 55 is fixedly connected to the linkage 52.

[0023] In the aforementioned wastewater chemical adaptive dosing device, after wastewater flows into the effluent regulating tank 51, the water flow continuously impacts the baffle plate 55. The impact force causes the baffle plate 55 to drive the linkage 52 to move to the right, thereby pressing the medicine tank switch 53. The greater the water flow, the greater the impact force on the baffle plate 55, and the greater the amount of medicine dispensed by the medicine tank switch 53. This achieves automatic adjustment of the amount of medicine dispensed according to the amount of wastewater, with a timely response.

[0024] In one embodiment of this utility model, the linkage 53 is a linkage rod, whose two ends are respectively connected to the water baffle 55 and the medicine box switch 53 to realize the linkage between the water baffle 55 and the medicine box switch 53.

[0025] In one embodiment of this utility model, a basket-type grille 60 is also included. The basket-type grille 60 is disposed inside the water outlet regulating tank 51 and is used to initially filter the water in the water inlet 101 to prevent large impurities from clogging the water outlet regulating tank 51.

[0026] In one embodiment of this utility model, the biological filter tank 30 is provided with a biological filter membrane 31, which is mainly used to remove COD, ammonia nitrogen, total phosphorus, suspended solids (SS) and trace pollutants (such as antibiotics and endocrine disruptors) from the water. It can be a combination of biofilm and hollow fiber membrane in a membrane bioreactor (MBR).

[0027] In one embodiment of this utility model, the upper end of the medicine box 54 is provided with a medicine inlet 541 for replenishing medicine.

[0028] In one embodiment of the present invention, the upper end of the medicine tank 54 is provided with a liquid level display, such as a radar liquid level display, for detecting the liquid level in the medicine tank 54.

[0029] In one embodiment of the present invention, the water outlet regulating box 51 includes a side box 511 and a bottom plate 512, the bottom plate 512 being inclined downwards to allow sewage to flow out.

[0030] In one embodiment of this utility model, a limiting step is provided at the position corresponding to the bottom plate 512 and the baffle plate 55 to prevent the baffle plate 55 from rotating into the interior of the water outlet regulating box 51, thereby preventing the baffle plate 55 from blocking the water outlet of the water outlet regulating box 51 and playing a role in preventing blockage.

[0031] In practical implementation, the medicine box switch 53 can be a piston-type valve core. Initial state: the spring is in its naturally extended state, pushing the piston valve core to tightly seal the water outlet channel (opening = 0, no water output). Pressing process: the linkage rod 52 moves to the right, the pressing rod of the piston valve core moves downward, overcoming the spring force through the lever structure, pushing the piston valve core upward—at this time, the "annular gap" (the gap between the valve core and the valve seat) of the water outlet channel increases with the pressing depth (opening increases), the cross-sectional area of ​​the water flowing through the gap increases, and the water output increases accordingly. Reset process: the linkage rod 52 moves to the right and left, releasing the pressing rod, the spring force pushes the piston valve core to reset, re-sealing the water outlet channel, and water output stops.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
