The role and significance of centrifuge for sludge treatment

- Jan 18, 2019-

With the development of the economy, people pay more and more attention to environmental protection issues, and at the same time, they are gradually aware of the importance of domestic sewage treatment and energy conservation and pollution discharge. It is more and more common for centrifuges to be used for sludge treatment. Wastewater treatment refers to the treatment of domestic production wastewater by professional sewage treatment equipment. The physical, chemical or biological treatment processes reduce or completely eliminate the pollutants contained in the sewage.


The centrifuge is mainly used for sludge treatment to treat some toxic pollutants in the sludge. The insoluble objects contained in the sewage are intercepted by the grille and sent to the sludge tank, which is produced by aeration through air flotation equipment. The residue will also be sent to the sludge tank. The sludge contains a small amount of pollutants, but it also contains harmful substances. It needs to be dewatered by sludge to achieve solid-liquid separation. Finally, it is discharged through the disinfection sewage, and the sludge is periodically transported or Use it.


The entire system unit is usually composed of sewage treatment equipment, sludge treatment equipment and disinfection equipment. The main function of the centrifuge for sludge treatment is to achieve solid-liquid separation. The working principle of the centrifuge is the difference in the speed of rotation. Due to the difference in the quality of the sewage and the quality of the sludge, the specific location in the equipment during the operation of the centrifuge is also different, so the purpose of solid-liquid separation is achieved.
