Municipal sewage treatment in Horizontal screw centrifuge It is usually used for sludge dewatering treatment. The main objective of municipal sewage treatment is to remove suspended solids, pollutants and organics in sewage, so as to achieve the purification of water quality and the attainment of discharge standards.
Recumbent snail Centrifuge The application in municipal sewage treatment is mainly to dewater and reduce the sludge generated in the treatment process. In the process of treatment, the suspended solids in the sewage form sludge after preliminary sedimentation, while the horizontal spiral centrifuge separates the moisture and solids in the sludge through the principle of rotating centrifugation.
The working principle of the horizontal spiral centrifuge is to feed sludge into the feed pipe of the centrifuge, and then deposit solid particles on the centrifuge wall to form a solid cake layer through the high-speed rotating centrifugal force, while the clean liquid is discharged from the outlet of the centrifuge. In this way, the water content of sludge is reduced to achieve the effect of reduction and dehydration.
The application of horizontal spiral centrifuge in municipal sewage treatment brings the following advantages: First, it can effectively reduce the water content of sludge, reduce the volume of treated sludge and treatment cost. Secondly, the volume of sludge is reduced, which can reduce the cost of transportation and disposal. In addition, the sludge dewatered by horizontal spiral centrifuge is easier to be subsequently disposed, such as solidification, incineration or recycling.
The model and parameters of horizontal spiral centrifuge shall be selected according to the actual situation of municipal sewage treatment to ensure that it can provide proper dehydration effect and meet the treatment requirements.
In summary, horizontal spiral centrifuge is mainly used for sludge dewatering and reduction treatment in municipal sewage treatment. Dewatering treatment can reduce the water content, volume and treatment cost of sludge, making it easier for subsequent disposal. This helps to realize the purification of municipal sewage and environmental protection.
