Background
Nitrogen and phosphorus are important biological nutrient sources, and with the common use of chemical fertilizers, detergents and pesticides, the content of nitrogen and phosphorus in natural water is increased rapidly, blue-green algae and green algae in the water are propagated in large quantities, and the water is anoxic and generates toxins, so that the water quality is deteriorated, and great harm is caused to aquatic organisms and human health. However, the existing urban sewage treatment plants in China mainly focus on removing organic matters, and the primary treatment of sewage (wastewater) only removes gravels and suspended solids in water; in aerobic biological treatment, domestic sewage is biodegraded, and most of soluble carbon-containing organic matters are removed.
Phosphorus exists in nature in two states: soluble state or particulate state. The phosphorus removal is to convert soluble phosphorus in water into granular phosphorus so as to achieve phosphorus-water separation. The process is called phosphorus release, in which the growth of phosphorus accumulating bacteria is inhibited under anaerobic conditions in the biological treatment of wastewater, polyphosphate in the cells of the wastewater is released for the growth of the wastewater, and the energy required for utilizing simple soluble organic substrates in the wastewater is generated. After entering an aerobic environment, the activity is fully recovered, and a large amount of dissolved orthophosphate is taken from the wastewater while the matrix is fully utilized, thereby completing the process of phosphorus accumulation. The microorganisms which absorb a large amount of phosphorus are removed from the wastewater, so that the aim of removing phosphorus can be fulfilled.
