Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically refers to a dosing pool for sewage treatment. Background Art

[0002] The dosing tank is a place in the sewage station where chemicals are added to react with sewage. Its main function is to collect sewage and purify the collected sewage. In traditional dosing tanks, after adding sewage treatment chemicals, they are usually slowly mixed with sewage over time. With the development of technology, people began to use stirring to accelerate the mixing and reaction.

[0003] Existing dosing tanks for sewage treatment, such as the dosing stirring tank for sewage treatment disclosed in application number CN202222272653.8, divide the tank body into a sewage storage tank and a reagent dilution tank, which can be used for reagent dilution and sewage treatment at the same time, and has the advantages of good sewage and reagent mixing effect and high efficiency.

[0004] However, in actual use, the scale of sewage treatment is usually large, and the volume of the dosing tank is relatively large. Stirring by means of agitator paddles is not suitable for large-scale stirring. A stirring paddle that is too long is not only easy to break, but also the rotation speed should not be too fast, resulting in a slow flow of sewage, which in turn affects the reaction speed between the treatment agent and the sewage. In particular, the enlarged structure is more laborious to install and maintain. For this reason, we propose a dosing tank for sewage treatment to solve the above problems. Utility Model Content
