[0002] Phosphorus removal refers to the removal of phosphorus from sewage. Phosphorus in sewage has the property of cyclic conversion between solid and dissolved forms. Sewage phosphorus removal is developed based on this property of phosphorus. Sewage phosphorus removal technologies include: chemical phosphorus removal, which turns phosphorus into insoluble solid precipitates and separates it from sewage; biological phosphorus removal, which makes phosphorus in dissolved form absorbed by microorganisms, becomes one with the microorganisms, and is separated from sewage along with the microorganisms. Different phosphorus removal technologies should be used according to the different existence forms of phosphorus in wastewater.
