Disc Diffuser in Sewage Treatment Plant

With the continuous development of urbanisation, sewage treatment has become an increasingly important environmental issue. In the process of sewage treatment, aeration is a key step, and the disc diffuser, as an important equipment, plays an important role in the sewage treatment plant.

Disc diffuser is a device used to inject oxygen into sewage. Its main principle is to inject gas into the sewage, so that the organic matter in the sewage is oxidised and decomposed, thus degrading the organic matter and reducing the pollutant content in the sewage. The disc diffuser forms bubbles by injecting air into the sewage, thus increasing the contact area between oxygen and sewage, promoting the dissolution of oxygen and accelerating the biodegradation reaction.

In sewage treatment plants, the disc diffuser has many advantages. Firstly, it can provide sufficient oxygen supply to promote the growth and activity of microorganisms in the sewage and improve the biodegradation efficiency. Secondly, the disc diffuser is simple to operate and easy to maintain, and does not require excessive manpower and technical support, reducing operation and maintenance costs. In addition, disc diffusers are compact and have a relatively small footprint, making them suitable for the construction of wastewater treatment plants on limited sites. Most importantly, disc diffusers do not produce secondary pollutants in the process of oxidising sewage, making them an environmentally friendly and efficient method of sewage treatment.

However, the application of disc diffuser also needs to pay attention to some problems. First of all, the choice of disc diffuser should consider the nature of sewage and the scale of treatment, to ensure that the performance of the equipment matches the demand. Secondly, attention needs to be paid to controlling the size and distribution of bubbles during operation, making full use of oxygen and improving the gas-liquid contact efficiency. In addition, regular maintenance is also necessary to maintain the stable operation of the disc diffuser.

In summary, disc diffuser, as an indispensable equipment in wastewater treatment plant, plays an important role in improving the efficiency of wastewater treatment, reducing the operation and maintenance costs, and achieving the goal of environmental protection. Through reasonable selection, operation and maintenance, disc diffuser will continue to play its great value in the field of wastewater treatment and contribute to the improvement of urban environment and sustainable development.
