Roots blower in river aeration treatment
The basic function of aeration is to produce and maintain air in effective contact with water, and maintain a certain dissolved oxygen concentration in water under the condition of continuous consumption of oxygen under the effect of biological oxidation. In the aeration zone, enough agitation is generated to promote the circulation of water and realize the full contact mixing of activated sludge and sewage. Keep the mixture moving at a certain speed to keep the activated sludge suspended in the mixture.
The working principle of Roots blower is to blow high-pressure air into the surface or bottom layer of water body, stir the sewage by promoting the continuous circulation of water flow, increase the contact area between sewage and air, make the activated sludge in a suspended state, fully mix and contact the organic matter, microorganism and oxygen, provide oxygen for aerobic microorganism, and ensure the normal growth and reproduction of microorganism. Effectively remove organic soluble inorganic salts with color and odor.
Roots blower has the dual functions of aeration and anaerobic mixing, which can accelerate the circulation of water and remove the organic matter that will not rot in water for a long time. It also has the functions of pre aeration, deodorization, preventing anaerobic decomposition of sewage, defoaming and accelerating the separation of oil in sewage. The organic matter in the water is absorbed and oxidized by the activated sludge to eliminate the black odor, remove the ammonia nitrogen and phosphorus in the sewage, effectively balance the ecosystem and greatly improve the water environment. Anaerobic fermentation can recover methane, reduce greenhouse gas emissions, and kill some parasitic eggs and pathogenic microorganisms.
Advantages of Roots blower: low noise and no negative impact on the surrounding environment. Aeration roots blower is generally used in breeding sewage, domestic sewage, hospital sewage, industrial sewage, mobile toilet sewage, sewage treatment station and animal farm.
