Product water quality requirements and corresponding processing procedures
When the wastewater discharge or reuse water quality requirements are low, only need to use screening and sedimentation methods to remove coarse impurities and suspended solids (often called primary treatment); when the removal of organic matter is required, it is generally used after the primary treatment Biological treatment method (often referred to as secondary treatment) and disinfection; the treatment process for wastewater after biological treatment is collectively referred to as tertiary treatment or advanced treatment, such as removal when the wastewater is discharged into the water body to prevent eutrophication The process of nitrogen and phosphorus belongs to the tertiary treatment (see the physical and chemical treatment of water). When wastewater is used as a water source, the quality of the finished water and the corresponding processing flow depend on its use. In theory, modern water treatment technology can produce any high-quality finished water from any poor-quality water.
