Description

Technical Field

[0001] The utility model relates to the technical field of sewage aeration, in particular to a surface water treatment device adopting air and ozone dual aeration. Background Art

[0002] During the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool comes into contact with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen. The organic matter in the sewage is decomposed aerobically. This process of forcing oxygen to be added to the sewage is called aeration.

[0003] Most of the traditional aeration treatment devices adopt corridor design, which needs to occupy a large amount of space, resulting in a huge waste of space. In addition, when treating various water bodies such as rivers and surface water, the traditional aeration treatment devices are bulky and have many structural parts. Since there are a lot of garbage impurities in the sewage, once these garbage enters the equipment, it is easy to damage the equipment, thereby shortening the service life of the equipment and making it troublesome to replace it later. For this reason, we have re-provided a surface water treatment device using air and ozone dual aeration, that is, air aeration is used in light pollution, and ozone aeration is used in heavy pollution to strengthen the treatment of pollutants in the water body. The dual aeration of air and ozone can efficiently and quickly treat various water bodies such as rivers and surface water. Utility Model Content
