Wastewater pretreatment methods primarily include physical, chemical, and biological methods. The specific methods are as follows: 1. Physical Pretreatment 1.1 Screens: Remove large particles (such as plastic and paper scraps) through interception. 1.2 Grit Chambers: Use gravity to separate inorganic impurities such as gravel and soil. 1.3 Grease Trap: Removes
The main differences between domestic and industrial wastewater treatment lie in the treatment targets, process flows, and pollutant types: 1. Differences in Treatment Targets Domestic wastewater treatment targets residential wastewater (including feces, laundry wastewater, etc.), with the core goal being to remove common pollutants such as chemical oxygen demand (COD),
The core differences between drinking water treatment and wastewater treatment lie in their treatment targets, objectives, and process flows: 1. Differences in Treatment Targets Drinking water treatment targets natural water sources (such as surface water and groundwater), aiming to remove suspended solids, microorganisms, and harmful substances to ensure water quality
