Term explanation: Aeration? Aeration is a method of bringing air into intense contact with water, aimed at dissolving oxygen from the air into the water, or removing unwanted gases and volatile substances from the water back into the air. In other words, it is a means of facilitating the exchange of substances between gases and liquids. It also has some other important functions, such as mixing and stirring. Aeration types are generally divided into two categories: one is air blast aeration, and the other is mechanical aeration. Blower aeration is a method of aeration that uses an aeration blower, aerators, diffuser plates, or diffuser tubes to introduce bubbles into water.
It refers to methods such as introducing air into water or mechanical stirring to increase the contact area between water and air, and it is an intermediate process in the aerobic biological treatment of wastewater.
It refers to the process of forcing oxygen from the air into a liquid, with the aim of obtaining sufficient dissolved oxygen. Furthermore, aeration also serves to prevent the suspended particles in the tank from sinking, and to enhance the contact between the organic matter in the tank, microorganisms, and dissolved oxygen. This ensures that the microorganisms in the tank can oxidize and decompose the organic substances in wastewater under conditions of sufficient dissolved oxygen.
Increasing the contact area between water and air by methods such as introducing air into the water or mechanical stirring is an intermediate process in the aerobic biological treatment of wastewater. It is a type of activated sludge process, also known as gradual aeration. The wastewater is introduced into the aeration tank in stages, which allows for uniform nitrogen consumption across all of the wastewater in the tank. Under these conditions, return sludge is fed in from the end of the aeration tank. The advantage of this method is its ease of adapting to changes in BOD load, as well as the relative simplicity in adjusting aeration time and sludge concentration.
It refers to the process of increasing contact between water and gas through methods such as inflation or mechanical stirring, in order to increase oxygen dissolution or remove dissolved gases and volatile substances from the water. Water and air come into full contact to exchange gaseous substances and remove volatile compounds from the water, or to allow gases to escape from the water, such as to eliminate unpleasant odors from water or harmful gases like carbon dioxide and hydrogen sulfide ； Or oxygen can be dissolved in water to increase the dissolved oxygen concentration, with the aim of removing iron and manganese or facilitating the degradation of organic matter by aerobic microorganisms. Aeration is mainly applied in the following two fields: aeration in aquaculture and aeration in wastewater treatment.
