Description

Technical Field

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

[0002] Wastewater treatment refers to the use of various physical, chemical or biological methods to separate, transform or degrade pollutants in sewage so that it meets specific water quality standards to meet the requirements of discharge or reuse. Sewage contains a large amount of difficult-to-degrade substances, and it is necessary to reasonably add sewage treatment agents based on the particularity of sewage quality so that the treated sewage meets national emission standards.

[0003] Chinese patent application number CN202320591410.2 discloses a sewage treatment dosing device, including a base plate, a lifting column and an adjustable dosing assembly. The base plate is used to support the various components of the device; the sewage pool is placed on the base plate; the lifting columns are fixedly assembled at both ends of the base plate for adjusting the depth of dosing; the top of the lifting columns is fixedly assembled with fixed blocks; the adjustable dosing assembly is placed between the fixed blocks and moves between the fixed blocks, and is used to add drugs into the sewage pool after cooperating with the lifting columns to adjust the height.

[0004] The above scheme uses the diverter column at the bottom of the medicine changing shell to add medicine for treatment. However, in actual use, the lifting column drives the medicine changing shell to descend in the sewage pool. The medicine liquid inside is difficult to flow out under the action of external water pressure, making it difficult to add medicine to the sewage pool. If the medicine is added on the water surface, the medicine liquid will have less contact with the liquid in the sewage pool, and the mixing effect will be poor.

[0005] In view of this, the present utility model is proposed. Utility Model Content
