Progress of Photosynthetic Bacteria Wastewater Resourcing
Photosynthetic bacteria wastewater treatment is an emerging technology that can simultaneously achieve waste-water purification and resource recovery. It can effectively reduce the concentration of organic matter, nitrogen, and phos-phorus in various wastewater. Moreover, the pigments, proteins, and coenzymes contained in PSB cells have high econom-ic benefits. Therefore, PSB cells can be collected to regenerate them resourcefully and solve the residual sludge problem while recovering many nutrients. The research development process of photosynthetic bacteria is sorted out, the applica-tions of photosynthetic bacteria in various types of wastewater treatment and other applications are introduced in detail, and new ideas for photosynthetic bacteria in wastewater treatment are proposed.
