Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a sewage treatment agent mixing device. Background Art

[0002] The rolling and rinsing processes in refined cotton production generate a certain amount of degradable industrial wastewater. During wastewater treatment, specific chemicals are often added to achieve solid-liquid separation within the sedimentation tank, thereby removing impurities and harmful substances. Wastewater treatment chemicals are typically mixed from multiple components using a mixing device. This device typically includes a storage, dosing, mixing, and control system that automatically adjusts the dosage and mixing speed based on the specific composition of the wastewater and treatment requirements.

[0003] Existing sewage treatment reagent mixing devices typically add the treatment reagent directly into the mixing device and then use a stirring device to mix the reagent and sewage. However, this process may result in insufficient dispersion of the reagent, resulting in uneven mixing. This uneven mixing state can negatively impact the treatment effectiveness of the reagent, leading to ineffective removal of pollutants from some sewage. To address this issue, we provide a sewage treatment reagent mixing device to address the aforementioned issues. Utility Model Content
