Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device with automatic chemical dosing. Background Art

[0002] Sewage treatment: The process of purifying sewage to meet the water quality requirements for discharging into a certain water body or for reuse. Sewage treatment is widely used in various fields such as agriculture, transportation, environmental protection, and catering, and is also increasingly entering the daily lives of ordinary people. In the process of sewage treatment, flocculants are required. Flocculants are chemical additives used to help fine particles or colloids in a liquid aggregate into larger lumps (called flocs), thereby improving the efficiency of solid-liquid separation. They are widely used in fields such as water treatment, sewage treatment, and mining. Flocculants change the chemical properties of the liquid, promote the interaction between particles, and enable the particles to settle or be filtered out more easily.

[0003] There is a sewage treatment device currently (its authorization announcement number is: CN221230028U). During the sewage treatment process of this sewage treatment device, there is a lack of a mechanism for automatically adding flocculants to the sewage filtration tank, which requires more manual intervention and increases the operation and maintenance costs. Therefore, we propose a sewage treatment device with automatic chemical dosing to solve the above problems. Summary of the Utility Model
