Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a foam driving device used in a sewage treatment pool. Background Art

[0002] The main pollutants in sewage include pathogen pollutants, oxygen-depleting pollutants, plant nutrients and toxic pollutants. In daily life, a large amount of wastewater, scum and other pollutants are generated. In order to protect the environment, sewage usually needs to be purified. In this process, a large amount of foam will be generated in the sewage. In order to remove the foam, a corresponding foam driving device is required.

[0003] The reference publication number is CN220165888U, which is a foam driving device for a sewage treatment pool. The foam driving device comprises a fixed column arranged in the sewage treatment pool, a mounting platform is arranged on the top of the fixed column, and a plurality of nozzles are arranged in a ring shape on the mounting platform, which are oriented outward and spray water to the middle of the sewage treatment pool in the outward direction to form a liquid level difference with the outer liquid surface. The device forms a liquid level difference between the middle and the outer side of the sewage treatment pool by arranging a plurality of nozzles spraying water in the outward direction in the sewage treatment pool. The foam in the sewage treatment pool is gathered to the edge with the flow of the liquid surface and then flows out to complete the foam elimination in the pool. In combination with the addition of a defoaming agent, the defoaming effect can be improved without manual cooperation for the later defoaming. According to the above, although the foam driving device can be well applied, it is usually not convenient to assist in the addition of the defoaming agent. The defoaming agent must be injected into the sewage treatment pool with the help of external tools, which often troubles people. Utility Model Content
