TECHNICAL FIELD

Moreover, these sludge also contains a high proportion of water and organic matter, which is difficult to separate by sedimentation. The traditional sludge treatment methods, such as landfill and incineration, not only have high costs but also have the risk of secondary pollution. Sludge reduction treatment has become an effective way to solve the problem of sludge treatment. The key to sludge reduction treatment is to separate wastewater from sludge in wastewater and to treat and recover the sludge. This not only helps the resource utilization of sludge, but also promotes the green and low-carbon development of wastewater treatment, and realizes the stabilization, harmlessness and resource utilization of sludge treatment.
