Description

Technical Field

[0001] The utility model relates to the technical field of Roots blower cooling, in particular to an air cooling structure for a Roots blower in an aerobic tank. Background Art

[0002] The Roots blower in the aerobic tank is crucial in the aerobic biochemical treatment stage of sewage treatment. Its working principle is to form an air flow through the relative rotation of the impellers, which can provide oxygen to meet the aerobic metabolism needs of microorganisms and stir and mix to prevent sludge sedimentation.
