Primary Treatment
摘要
Primary treatment holds immense importance in municipal sewage treatment plants as it primarily focuses on the removal of solid materials and heavy organic particles from the wastewater. This stage is crucial because untreated wastewater contains a significant amount of suspended solids, debris, and other organic matter, which, if not removed, can result in severe environmental and public health concerns. Primary treatment acts as a preliminary barrier, reducing the organic load and solids content of the wastewater before it undergoes further treatment.
