Blowers play a key role in wastewater treatment, helping to improve the quality of wastewater and achieve energy saving and emission reduction. The main steps in wastewater treatment include pre-treatment, biological treatment and deep treatment. Blowers play an important role in all three stages, including increasing the oxygen content in the water, removing volatile substances in the water and bottom sediments.

In the pre-treatment stage, the blower can introduce the oxygen in the air into the water through aeration to increase the dissolved oxygen content in the water, provide sufficient oxygen for microorganisms, and promote the growth and reproduction of microorganisms. At the same time, the blower can also be stirred, so that the sewage and air full contact, promote the decomposition and degradation of organic matter in sewage.

In the biological treatment stage, the blower can provide sufficient oxygen for the biological reactor through aeration, promote the growth and reproduction of microorganisms, and improve the efficiency of biological treatment. At the same time, the blower can also make the sewage and microorganisms in the bioreactor mix fully through stirring to improve the effect of biological treatment.

In the deep treatment stage, the blower can provide sufficient oxygen for the membrane bioreactor through aeration, promote the growth and reproduction of microorganisms, and improve the treatment effect of the membrane bioreactor. At the same time, the blower can also make the sewage and microorganisms in the membrane bioreactor mix sufficiently through the stirring effect to improve the treatment effect of the membrane bioreactor.

With the continuous development of science and technology, the types and performance of blowers are also improving. For example, high-pressure blowers have the advantages of compact structure, high efficiency and intelligence, integration, and low operating costs, which are suitable for small and medium-sized sewage treatment systems. In addition, the energy-saving frequency converter has the characteristics of strong energy-saving effect, reliable performance, simple structure, etc. If the technology can be adopted for the blower, it can roughly solve about 30% of the electricity consumption.

In short, the blower plays a key role in sewage treatment, helping to improve sewage water quality, energy saving and emission reduction. With the continuous development of science and technology, the types and performance of blowers are also improving, providing more efficient, energy-saving, environmentally friendly solutions for sewage treatment.
