Description

Technical Field

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

[0002] The process of purifying sewage to ensure that it meets the water quality requirements for discharge into a water body or reuse is sewage treatment. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. With the continuous development of the times and the continuous progress of society, water pollution is getting worse.

[0003] In the prior art, the centralized sewage treatment environment is generally treated by adding drugs. However, the adding method in the prior art usually adopts manual adding. When different types of drugs need to be added, they are usually taken manually. The efficiency of adding drugs is relatively low. At the same time, long-term manual adding of drugs causes physical and mental harm to the staff.

[0004] In order to solve the above technical problems, a Chinese document (publication number CN110841507A) discloses a classified dosing device for sewage treatment, including a space between several vertical partitions and between the vertical partitions and the left and right side walls of the box as a drug storage bin, and the several drug storage bins are arranged in coordination with the outlet ends of several feed hoppers; several stirring blades are fixedly provided with equal rounded corners on the rotating shaft inside the box; a suction pump is fixedly provided on the inner bottom surface of the box; a liquid guide tube is fixedly connected to the output end of the suction pump, and the liquid guide tube passes through the right side wall of the box and extends to the right side of the box; a dosing mechanism is provided on the right side of the box.

[0005] The above technical solution separates different types of liquid medicines through vertical partitions, and introduces different types of liquid medicines from the medicine storage bin into the box body according to the order of adding medicines. However, in actual use, different medicines are added according to the sewage situation. After the medicines added in the previous round of sewage situation of the above technical solution are used up, the box body needs to be cleaned to prevent the medicines used in the previous round of sewage treatment from adhering to the inner surface of the box body and affecting the sewage treatment effect of the next round, which greatly increases labor costs. At the same time, the above technical solution directly inputs the medicine into the sewage in the box body, and the medicine and sewage are easily not completely dissolved during the mutual fusion, resulting in poor sewage treatment effect.
