1, is the environmental protection of water treatment biological contact oxidation process of microorganisms in the oxygen required through the sewage treatment fan aeration supply, which is characterized by the set up of filler in the pool, the bottom of the pool aeration of the sewage oxygenation, and to make the pool of sewage in the flow state.
2, to ensure that the sewage and submerged in the sewage filler full contact, to avoid the biological contact oxidation pool in the presence of sewage and filler contact uneven defects, we say that the role of the blower for the sewage treatment fan.
Commonly used several kinds of fans
1.Roots fan. Roots blower is used when the load requires a constant flow effect. Because the Roots blower belongs to the constant flow fan, the main parameter of the work is the air volume, the output pressure changes with the pipeline and the load changes, the air volume changes are very small. Roots fan is a kind of high-pressure fan, Roots blower is a volumetric fan, the volume of air delivered is proportional to the number of revolutions, and the gas is transported from the side of the inhalation to the discharge.
2. Centrifugal fan. If the load is required is the constant pressure effect of the situation when the centrifugal fan. Because the centrifugal fan belongs to the constant pressure fan, the main parameter of the work is the wind pressure, the output of the air volume with the pipeline and the load changes, the wind pressure does not change much. With centrifugal fans, the air pressure is not large. The compression of air is usually carried out by centrifugal force through several working impellers (or stages). Centrifugal fans are of the square torque characteristic, while Roots fans are basically of the constant torque characteristic.
3. Rotary fans. Roots blower generally speaking, the air volume is relatively large, the pressure is also relatively large, the same Roots fan noise is also very large, if you need to air volume is relatively small, the noise requirements are relatively high, the use of rotary blower, rotary blower also belongs to the constant-flow fan, the main parameter of the work of the air volume, the output pressure with the pipeline and the load changes, the change in the volume of the air change is very small, the rotary blower is a variable-capacity compression, the main characteristics of its Is: low speed, low noise, low vibration, high efficiency, high energy saving.
