Aeration Device for Efficient Purification of Contaminated Water

This patent relates to an aeration device and method for efficiently purifying contaminated water containing volatile organic compounds. The device combines a nozzle that forcibly pushes air in and a packing layer that disperses contaminated water. Since the air flow rate can be adjusted, harmful substances in the contaminated water can be efficiently removed. Furthermore, by commonizing the air supply device and circulating exhaust air, energy saving and device downsizing are realized.

• Space saving by commonizing the air supply device
• Temperature stabilization and energy saving through exhaust circulation
• Optimization of purification efficiency by adjusting the gas-liquid ratio

Conventional contaminated water purification devices only take in air naturally, which does not provide sufficient aeration effect, resulting in low removal efficiency of volatile organic compounds. Additionally, the devices tend to become large, requiring more installation space and higher operating costs. Furthermore, it was difficult to adjust the gas-liquid flow ratio (gas-liquid ratio), making efficient operation management challenging and stable purification performance hard to maintain.

This invention uses a blower that forcibly pushes air to mix a larger amount of air into contaminated water through the nozzle, enhancing aeration efficiency. Air is also supplied to the packing layer that disperses contaminated water, allowing adjustment of the gas-liquid ratio. Moreover, by integrating the air supply device into one and circulating exhaust air, the device is downsized, achieving energy saving and cost reduction. This enables stable and highly efficient purification of contaminated water.

• Technology capable of efficiently removing harmful substances from contaminated water
• Technology that enables downsizing of the device and space-saving
• Technology that maintains high performance while reducing operating costs
