Description

Technical Field

This process is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. Sewage contains a large amount of suspended solids and organic matter. These substances will go through stages such as sedimentation and biodegradation during the sewage treatment process, and some of them will form sludge. Sludge discharge can effectively remove these substances and reduce their content in sewage, thereby improving the quality of treated water.
