[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a wastewater treatment system. (Refer to...) Figures 1-5 A sewage treatment system includes a sewage treatment tank 1, a quantitative dosing mechanism 3 on the top of the sewage treatment tank 1, a partition 11 inside the sewage treatment tank 1, a grid plate 12 on one side of the partition 11, a sewage pump 21 near the partition 11 on one side of the sewage treatment tank 1, and a flow meter 22 at one end of the sewage pump 21. By introducing domestic sewage into one side of the partition 11 of the sewage treatment tank 1, coarse filtration is performed by the grid plate 12. After settling, the sewage from one side of the partition 11 is introduced to the other side of the partition 11. At the same time, the flow meter 22 monitors the flow data and controls the quantitative dosing mechanism 3 to perform quantitative dosing, thereby achieving the purpose of quantitatively dispensing agents according to the sewage flow rate, thus improving the sewage treatment effect. In this embodiment, the flow meter 22 used is a sewage flow meter 22, which is existing technology. Its principle is to measure the volumetric flow rate of sewage in pipes or channels. It consists of a water level and flow velocity sensor, a host computer, and a communication cable. It is widely used in municipal water supply, environmental protection, industrial monitoring and other fields. The quantitative dosing mechanism 3 includes a medicine tank 31, which is located on top of the wastewater treatment tank 1. A weighing sensor 32 is installed along the top edge of the medicine tank 31, and a delivery pipe 35 is installed at the bottom of the medicine tank 31. One end of the delivery pipe 35 extends into the interior of the wastewater treatment tank 1, and a plug 36 is installed inside the delivery pipe 35. A through groove 37 is formed on the surface of the plug 36. A motor 38 is installed on the top of the wastewater treatment tank 1, and the motor 38 drives the plug 36 to rotate, thereby introducing the medicine into the medicine tank 31 and driving the plug 36 by the motor 38. Rotating and flipping one side of the plug 36 so that the through groove 37 on the surface of the plug 36 faces upward, thereby connecting the medicine tank 31 with the delivery pipe 35. The medicine in the medicine tank 31 flows from the medicine tank 31 into the sewage treatment tank 1 through the delivery pipe 35. The weighing sensor 32 monitors the amount of medicine reduction in the medicine tank 31 in real time. After the predetermined target is reached, the motor 38 drives the plug 36 to flip one side again so that the through groove 37 faces downward, thereby sealing the delivery pipe 35 and stopping the delivery of medicine in the medicine tank 31, thus achieving the effect of quantitative control of medicine dosing.

[0018] Reference Figure 1 , Figure 2 and Figure 4 A side groove 2 is provided on the outside of the sewage treatment tank 1 near the partition 11. The sewage pump 21 is fixedly connected inside the side groove 2. One end of the sewage pump 21 is fixedly connected to the connecting pipe 23. One end of the flow meter 22 is set on the outer wall of the connecting pipe 23 and extends out of the side groove 2. By introducing domestic sewage into the sewage treatment tank 1, the sewage pump 21 in the side groove 2 introduces the sewage that has been coarsely filtered by the grid plate 12 on one side of the partition 11 into the other side of the partition 11. The sewage is introduced into the other side of the partition 11 through the connecting pipe 23. At the same time, the flow meter 22 on the outer wall of the connecting pipe 23 detects the flow data in real time. Based on the flow data of the flow meter 22, the quantitative dosing mechanism 3 can be controlled to do quantitative dosing, thereby achieving the purpose of quantitatively dispensing the agent according to the flow data of the flow meter 22.

[0019] Reference Figure 1 , Figure 3 and Figure 5A support 33 is fixedly connected to the top of the sewage treatment tank 1, and a weighing sensor 32 is fixedly connected to the top of the support 33. A discharge pipe 34 is provided at the bottom of the medicine tank 31. One end of the discharge pipe 34 is fixedly connected to the outside of the conveying pipe 35 near the plug 36. A sealing sleeve 311 is provided on the outer wall of the plug 36, and the sealing sleeve 311 contacts the inner wall of the conveying pipe 35. One end of the plug 36 extends out of the end of the conveying pipe 35 and is rotatably connected to the conveying pipe 35. A second gear 310 is fixedly connected to the end of the plug 36. A first gear 39 is fixedly connected to the output end of the motor 38. The first gear 39 meshes with the second gear 310. By using the weighing sensor 32 installed on the support 33, the weighing sensor can be used to realize the weighing sensor 32. The amount of medicine reduced in the medicine tank 31 is monitored in real time. The first gear 39 is driven by the motor 38. The first gear 39 and the second gear 310 work together to drive the plug 36 to rotate and flip one side, so that the through groove 37 of the plug 36 is connected to the feed pipe 34. This allows the medicine in the medicine tank 31 to be introduced into the sewage treatment tank 1 through the feed pipe 34, the plug 36 and the conveying pipe 35. After the weighing sensor 32 detects that the amount of medicine reduced has reached the predetermined target, the plug 36 is driven by the motor 38 to flip one side again, so that the outer wall of the plug 36 seals the bottom of the feed pipe 34 and, together with the sealing sleeve 311, seals the conveying pipe 35, thereby stopping the delivery of medicine and achieving the effect of quantitative control of medicine dosing.

[0020] Working principle: During use, domestic sewage is introduced into the sewage treatment tank 1, and the reagent is introduced into the reagent tank 31 of the quantitative dosing mechanism 3. The sewage pump 21 in the side channel 2 introduces the sewage that has been coarsely filtered by the grid plate 12 on one side of the partition 11 to the other side of the partition 11. The flow meter 22 on the outer wall of the connecting pipe 23 detects the flow rate of the sewage in real time to coordinate with the quantitative dosing. The dosage is determined according to the flow data of the flow meter 22. The motor 38 drives the first gear 39 to cooperate with the second gear 310 to drive the plug 36 to rotate and flip. Turning one side connects the discharge pipe 34 of the channel 37, allowing the medicine in the medicine tank 31 to be introduced into the sewage treatment tank 1 through the discharge pipe 34, the plug 36, and the conveying pipe 35. The weighing sensor 32 on the bracket 33 detects the decrease in the medicine in the medicine tank 31. After the predetermined amount of medicine is reached, the motor 38 drives the plug 36 to turn the other side again, so that the outside of the plug 36 seals the end of the discharge pipe 34 and, together with the sealing sleeve 311, prevents the medicine from continuing to be conveyed, thereby achieving the purpose of quantitatively dispensing medicine according to the sewage flow rate.
