Description

Technical Field

[0001] The utility model relates to the technical field of drug dosing equipment, in particular to a drug dosing equipment capable of automatically adjusting drug delivery rate. Background Art

[0002] A sewage treatment dosing system is a device used to add chemicals to the water during the sewage treatment process. These chemicals typically include flocculants, coagulants, disinfectants, etc. They play a key role in sewage treatment, such as flocculation, disinfection, and pH adjustment. The dosing system is designed to ensure that the chemicals are accurately and evenly added to the sewage to achieve the best treatment effect.
