Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and more specifically, it relates to a chemical dosing wastewater treatment device for wastewater treatment. Background Technology

[0002] Chemical dosing wastewater treatment devices are specialized equipment that remove pollutants from wastewater by adding specific chemicals, utilizing chemical reactions, physical adsorption, or biological synergy, thereby purifying the water. These devices are widely used in municipal wastewater treatment, industrial wastewater treatment, and circulating water treatment. However, commonly used chemical dosing wastewater treatment devices may lead to excessive chemical addition, resulting in waste and excess chemicals settling into ineffective sludge. Therefore, a new type of chemical dosing wastewater treatment device is needed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a wastewater treatment device for chemical dosing, which solves the problem of waste caused by excessive chemical dosing during the chemical dosing process in existing wastewater treatment devices.

[0004] This utility model discloses a wastewater treatment device for chemical dosing, which is achieved by the following specific technical means:

The fixed baffle is placed at the upper end of the outer shell, and a movable baffle is connected to the fixed baffle. A connecting pipe is connected to the movable baffle, and a filter tank is installed on the connecting pipe. The two sets of aerators are placed in the round holes on the positioning plates on the left and right sides of the outer shell, and a set of gas connecting pipes is connected to the lower end of the two sets of aerators, and the gas connecting pipes penetrate into the interior of the outer shell.

[0007] Furthermore, a second fixing frame is installed on the upper side of the fixing baffle, and a storage tank is connected to the second fixing frame. The lower end of the storage tank is connected to a feed pipe, and the lower end of the feed pipe extends into the interior of the outer shell. An electrically controlled valve is installed on the feed pipe.

[0008] Furthermore, the fixed baffle is provided with a positioning component A, and a connecting rod is fixedly connected to the lower end of the positioning component A. The connecting rod is placed inside the outer shell, and a water quality detection sensor and a reagent concentration sensor are installed on the connecting rod. The reagent concentration sensor is electrically connected to the electrically controlled valve.

[0009] Furthermore, two sets of fixing rods are fixedly connected inside the outer shell, and a waterproof outer shell is connected to the inner side of the two sets of fixing rods.
