Description

an aeration device

technical field

The utility model relates to the technical field of water treatment of environmental protection equipment, in particular to an aeration device.

Background technique

With the rapid development of social economy, urban industrial wastewater, domestic sewage, agricultural non-point source pollution, etc., cannot achieve complete interception in many cases and flow into natural or artificial water bodies, which seriously exceeds the self-purification capacity of natural or artificial water bodies. This makes it impossible to achieve self-healing, leading to the deterioration of water quality, black and smelly water and other problems. Supplementing dissolved oxygen in the water body to promote the metabolic decomposition of pollutants by aerobic microorganisms in the water body is an effective way to suppress the black and odor of the water quality. Therefore, aeration and oxygenation of the water body has become an effective way to purify the water body.

At present, the commonly used aeration methods in water bodies include water cultivators, aerators, drop water aeration, blowers with aeration tubes, etc., but these measures only aerate the water body to increase the dissolved oxygen content in the water body to promote good water in the water body. The metabolic decomposition of pollutants by aerobic microorganisms has a single function. For this reason, existing patent has been improved. For example, the Chinese utility model patent with the patent number ZL201720214907.7 (announcement number: CN206666227U) discloses an "Integrated System for Ecological Restoration of Rivers and Lakes with Wind-solar Complementary System", which consists of three water restoration methods: aeration, carbon fiber water plants and microorganisms. The integrated system includes fixed piles, a central floating island platform, an aeration system, a wind-solar hybrid power supply system and a peripheral landscape belt to restore eutrophic surface water bodies such as rivers and lakes. But in this patent, carbon fiber aquatic plants (ie artificial aquatic plants) are vertically suspended below the supporting floating body. In this way, the artificial aquatic plants have less obstructive effect on the rising process of the air bubbles generated by aeration, the contact time between the air bubbles and the water body is shorter, the aeration efficiency is lower, and the aeration efficiency can be further improved.
