Roots blowers are critical components in wastewater treatment facilities. These positive displacement machines generate high-pressure air that is essential for the aeration process. The blower takes in atmospheric air and compresses it, then delivers this pressurized air to aeration tanks where it provides oxygen for biological treatment processes.
The oxygen supply process begins when the roots blower delivers pressurized air through pipes to diffusers located at the bottom of aeration tanks. These diffusers release fine air bubbles that rise through the wastewater. As the bubbles ascend, oxygen dissolves into the liquid, increasing the dissolved oxygen concentration throughout the tank.
罗茨风机提供的溶解氧为活性污泥中的好氧微生物创造了理想条件。这些有益的细菌和其他微生物以有机污染物为食物来源。通过细胞呼吸，它们将复杂的有机化合物分解为更简单、无害的产物，如二氧化碳和水，同时繁殖形成新的微生物细胞。
The aeration process creates powerful mixing and circulation effects within the treatment tank. Rising air bubbles generate turbulent flow patterns that thoroughly mix the wastewater contents. This circulation ensures that dissolved oxygen, activated sludge, and organic pollutants are evenly distributed, maximizing contact between microorganisms and their food source, which significantly improves overall treatment efficiency.
Roots blowers find extensive application in various biological wastewater treatment processes. They are essential in activated sludge systems, contact oxidation processes, sequential batch reactors, and membrane bioreactors. These applications span municipal wastewater treatment plants, industrial facilities, food processing plants, and chemical industries. The reliable oxygen supply provided by roots blowers ensures consistent biological treatment performance across all these diverse applications.
