[0002] In the field of sewage treatment, the chemical dosing process is one of the core links, and its efficiency directly affects the pollutant removal effect and operating costs. With the increasingly stringent environmental protection standards and the development of smart water services, the limitations of existing technologies have become increasingly prominent. The dosing systems of traditional sewage treatment equipment generally have problems such as low agent dosing accuracy and poor mixing effect, resulting in limited treatment efficiency and serious waste of resources. Therefore, we propose a sewage treatment equipment with efficient dosing function.

[0003] The prior art also has the following defects during use:

[0004] 1. The existing sewage treatment equipment has a relatively centralized dosage of chemicals, and requires stirring to promote contact and mixing between chemicals and sewage to ensure that the chemicals have a good treatment effect on sewage. However, this method relies heavily on an external stirring mechanism, which has certain requirements for the mixing effect of the stirring mechanism.

The rotation speed and blade design of the stirring paddle are difficult to adapt to the changes in water quality and water volume. The contact time between the reagent and sewage is long and the uniformity is poor. This problem is particularly prominent when treating high-salt and high-turbidity sewage.

[0006] In view of this, we propose a sewage treatment equipment with efficient dosing function to solve the existing problems. Utility Model Content

The water inlet pipe 207 allows the untreated sewage to flow into the tank body 2. The support column 202 can support the tank body 2, thereby ensuring the stability of the tank body 2 and its surrounding components. The bottom plate 203 can expand the support area of ​​the bottom of the device, thereby improving the stability of the device. The drug supply pump 204 adopts the JIH125-80-160 model.

[0049] Furthermore, a butterfly valve is fixedly installed at the connection position between the drain pipe 206 and the tank body 2. The butterfly valve can control the opening and closing of the drain pipe 206 so that the sewage can be discharged from the tank body 2 from the drain pipe 206 after treatment.

[0050] Working principle: After the device is assembled, the drug supply pump 204 and the sewage pump 1 are connected to the pipeline respectively. The chemical agent is sucked by the drug supply pump 204, and the chemical agent is introduced into each guide ring 402 through the injection pipe 205, the connecting pipe 503 and the central pipe 404 for uniform distribution. At the same time, the sewage pump 1 draws the untreated sewage into the tank body 2, and guides the sewage to flow vertically from the top of the tank body 2 through the water inlet pipe 207. After the sewage contacts the separation frame 3, the solid impurities mixed in the sewage are guided by the separation frame 3 to fall on the drainage ring 504 and discharged from the tank body 2 through the sewage hole 201. The sewage then drips along several guide rods 301 onto the guide ring 402 and contacts the chemical agent in the guide ring 402. The sewage after contacting the chemical agent overflows from the guide ring 402 and finally falls into the inside of the inner cylinder 5. After being completely mixed, it flows from the drainage cylinder 502 into the drainage pipe 206 and then discharged from the tank body 2, completing the efficient dosing treatment of the sewage.
