Application and effect of Sewage treatment air diffuser

- Oct 22, 2018 -

In the field of water treatment, biological treatment is a commonly used and very cost-effective treatment method. According to the aerobic conditions of microorganisms involved in the operation of Sewage treatment air diffuser, it can be divided into aerobic method and anaerobic method. class. Under normal circumstances, the aerobic method is more suitable for lower concentration sewage, such as ethylene plant sewage; and the anaerobic method is more suitable for treating sludge and higher concentration of sewage.


In the process of using sewage treatment aerator, according to the operation situation, in the aeration tank of the sewage treatment biochemical system, the oxygenation efficiency is positively correlated with the growth of aerobic microorganisms. The amount of dissolved oxygen supplied should be considered in consideration of the number of aerobic microorganisms, physiological characteristics, matrix properties and concentration. In this way, the activated sludge can be in an optimal state of degrading organic matter.


It should be noted that in the process of use, the dissolved oxygen in the aeration tank of the sewage treatment aerator needs to be maintained within the range of 3 to 4 mg/L. If the oxygen supply is insufficient, the performance of the activated sludge is poor, resulting in a decrease in the treatment effect of the wastewater. In order to ensure adequate oxygen supply, it must be done by means of a device, such as an aerator.
