It is widely used in municipal, industrial and domestic wastewater treatment. Urban domestic wastewater mainly consists of various detergents, sewage, garbage and feces used in urban life. It is mostly non-toxic inorganic salts, and contains a relatively high amount of elements such as nitrogen, phosphorus and sulfur. Due to the influx of household water, initial rainwater and washing wastewater, the nitrogen and phosphorus in domestic wastewater seriously exceed the standards, and the values ​​of COD and BOD are also increasing. Moreover, domestic wastewater can cause pathogen pollution, eutrophication pollution, acid, alkali and salt pollution, etc. Therefore, it is necessary to treat urban wastewater through wastewater treatment equipment.

[0003] An existing wastewater treatment device (announcement number: CN219259781U) has at least the following drawbacks: When adding chemicals, the device requires manual delivery of the chemicals through a dosing pipe. The dosing method mainly relies on manual operation, requiring staff to measure the wastewater flow and add an appropriate amount of chemical agents. Due to the high workload of manual dosing, operators need to frequently check the wastewater flow and manually add chemicals, which is time-consuming and labor-intensive, reduces wastewater treatment efficiency, and cannot automatically add chemicals according to the wastewater flow.

[0022] Reference Figure 1 - Figure 4An adjustable flow sewage treatment dosing device includes a sewage treatment tank 1, a filter box 2 fixedly connected to the top of the sewage treatment tank 1, a reagent storage tank 3 fixedly connected between the top of the sewage treatment tank 1 and the side wall of the filter box 2, a limit plate 4 fixedly connected to the bottom of the inner wall of the sewage treatment tank 1, a floating threaded rod 5 slidably connected through the inside of the limit plate 4, and a floating block 6 threadedly connected to the outer wall of the floating threaded rod 5. The sewage treatment tank 1 is equipped with a dosing mechanism that adjusts the flow rate of sewage according to the flow rate inside the sewage treatment tank 1. The dosing mechanism includes a diffuser plate 7 fixedly connected to the top of the floating threaded rod 5, the diffuser plate 7 being umbrella-shaped, a hollow cylinder 8 fixedly connected to the top of the diffuser plate 7, and discharge ports 9 on both sides of the bottom of the hollow cylinder 8. A discharge cylinder 10 is connected to the bottom of the reagent storage tank 3, and a discharge pipe is fixedly connected to the side wall of the discharge cylinder 10. 11. A through groove 12 is provided on the side wall of the feeding cylinder 10. The outer wall of the hollow cylinder 8 is slidably connected to the inside of the feeding cylinder 10. A fixing plate 13 is fixedly connected to the inside of the feeding cylinder 10. A spring 14 is fixedly connected to the bottom of the fixing plate 13. An L-shaped plate 15 is fixedly connected to the bottom end of the spring 14. The L-shaped plate 15 is slidably connected to the inner wall of the feeding cylinder 10. A first rack 16 is attached to the side wall of the hollow cylinder 8. A gear 17 is rotatably connected to the outer wall of the feeding cylinder 10. A second rack 18 is fixedly connected to the side wall of the L-shaped plate 15. The two sides of the gear 17 mesh with the side walls of the first rack 16 and the second rack 18, respectively. Two filter screens 19 are fixedly connected inside the filter box 2. The two filter screens 19 are arc-shaped and on the same vertical line. An outlet 20 for draining sewage from the inside of the sewage treatment tank 1 is connected to the side wall of the sewage treatment tank 1.

[0023] In this embodiment, when the dosing mechanism is in use, sewage is poured into the filter box 2 through a pipe. After preliminary filtration by two filter screens 19, the sewage flows into the sewage treatment tank 1. Before dosing, the height of the floating block 6 can be adjusted by rotating the floating block 6 on the outer wall of the floating threaded rod 5. When the sewage flows into the sewage treatment tank 1 to the adjusted height, the dosing mechanism is activated. As sewage continues to enter the sewage treatment tank 1, the floating block 6 floats and drives the floating threaded rod 5 to move upward. The movement of the floating threaded rod 5 causes the diffuser plate 7 and the hollow cylinder 8 to rise together. The rise of the hollow cylinder 8 pushes the first rack 16. The movement of the gear 17 causes the second rack 18 to move downwards, which in turn causes the L-shaped plate 15 to move downwards and stretch the spring 14. Since the L-shaped plate 15 is L-shaped, its sidewalls will block the top of the feed pipe 11. As the L-shaped plate 15 continues to descend, the agent in the agent storage tank 3 will enter the feed pipe 11. The agent can be granular or liquid. Then, it enters the outlet 9 through the bottom of the hollow cylinder 8 and flows into the diffuser plate 7. The design of the diffuser plate 7 makes the agent diffuse evenly in all directions, thereby increasing the coverage area of ​​the agent and ensuring more effective sewage treatment.

[0024] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: the dosing mechanism adjusts the dosage according to the changes in sewage flow, which solves the shortcomings of manual dosing that relies on manual flow measurement and manual dosing, reduces the intensity of operation, and improves the accuracy and stability of dosing. Compared with the traditional manual method, automated dosing can adjust the dosage in real time according to the changes in sewage flow, ensuring uniform dosing of the agent and treatment effect, which greatly improves the efficiency and reliability of sewage treatment. At the same time, it also reduces the frequency of manual operation, reduces the labor intensity of the staff, and further improves the overall operating efficiency of the sewage treatment system.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
