Roots blower is a fan commonly used in the aeration system, the main role is to compress and transport the air to the aeration pool, in order to increase the oxygen content in the aeration pool, to promote the aerobic reaction in the biological treatment process. Therefore, Roots blower has an important role in the aeration system, and its aeration role is mainly reflected in the following aspects:

1. Provide oxygen: By compressing and delivering air to the aeration tank, Roots blower can increase the oxygen content in the aeration tank, provide necessary oxygen for microorganisms, and promote microbial metabolism and growth, thus accelerating the treatment of wastewater.
2. Stirring and mixing: The bubbles and airflow generated by the Roots blower can stir and mix the liquid in the aeration tank, so that the organic substances in the wastewater are more uniformly dispersed in the water, and the contact area between the microorganisms and the wastewater is improved, thus enhancing the effect of biodegradation.
3. Maintaining temperature: The microorganisms in the aeration tank need the right temperature to carry out the biological reaction normally. By conveying air, the Roots blower can fully contact the liquid in the aeration tank with the outside air, so as to keep the temperature in the aeration tank stable.
