Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an intelligent automatic medicine dispensing and dosing system. Background Art

[0002] Sewage usually contains a large amount of suspended matter, colloids and other substances, and some of the suspended matter has a small particle size, light specific gravity, and slow sedimentation rate. In order to improve its sedimentation effect, there is usually an important process link in the water treatment process - the coagulant (PAC, PAM) addition process; the operation and maintenance workers need to mix the powdered coagulant and water into a certain concentration of liquid according to the proportion, and the prepared solution is transported to the water treatment equipment area through the dosing pump and fully mixed with the sewage.

[0003] In traditional processes, maintenance workers need to prepare liquid medicines regularly to ensure the continuous operation of the water treatment process. The traditional manual preparation method is to manually carry the medicine into the solution bucket and mix it with water in a certain proportion. For large-scale water treatment stations, workers have a large workload of carrying medicines every day and the labor intensity is high. In particular, the odor emitted by some medicines causes great harm to the human body, resulting in the manual dosing method becoming less and less suitable for the requirements of modern processes.

[0004] In addition, traditional manual dosing has many shortcomings, such as untimely and inaccurate dosing; the dosage needs to be set in advance by the operation and maintenance personnel, and the dosage cannot be automatically adjusted according to changes in the incoming water quality and the outgoing water quality, which may cause waste of dosage, or insufficient dosage and substandard outgoing water quality.

[0005] Therefore, in order to reduce the number of inspections and medication dispensing by operation and maintenance personnel, the present application proposes an intelligent automatic medication dispensing and dosing system that can automatically configure the medicine solution and automatically perform parameter adjustments according to the water load and operating conditions, thereby maximizing work efficiency and reducing the operating burden on workers.
