Aeration site of Roots blower in Xiamen, Fujian Province
The figure below shows the site of Roots blower aeration in the sewage treatment system of Xiamen Meijie company in Fujian Province. It is the site photo sent to us by the staff of Meijie company. The customer purchased msr150 from us in 2013 A Roots blower The air volume is 20 m3 / min, the pressure is 58.8 kPa, the supporting motor is 37 kW, and the fan speed is 1450 rpm. In October of this year, Meijie company signed a purchase contract with us to purchase a msr150 roots blower with the same model parameters. According to the parameters of the fan, the fan can be divided into belt drive and direct drive. Through introduction, customers still choose the belt drive.

II. Principle of blast aeration
Activated sludge treatment of sewage is an aerobic biological treatment. It is necessary to rely on aerobic microorganisms to absorb organic matter in water and oxidize and decompose to form carbon dioxide and water, and at the same time make it self diffusion. In this process, it is necessary to provide enough dissolved oxygen to microorganisms in activated sludge to meet the requirements of microbial growth and metabolism. Roots blower aeration first realizes the process of oxygen transportation. The principle of the system is to transfer oxygen from air to water through air water contact. Therefore, the calculation of air volume in blast aeration is also based on the oxygen demand of microorganisms, combined with environmental factors, water quality conditions, aeration efficiency and other transfer factors.
In the process of mixing and mixing, on the one hand, the activated sludge is suspended in the aeration tank and fully contacts with the sewage, which improves the mass transfer conditions of pollutants in the water treatment system and improves the treatment effect. On the other hand, roots blower provides good conditions for oxygen diffusion and transfer in liquid phase.
