Research Progress and Future Trends of Nitrogen and Phosphorus Removal Technologies in Wastewater Treatment Plants
Downloads
: This paper focuses on the nitrogen and phosphorus removal technologies in wastewater treatment plants, elaborating on their research progress, development status, and future trends. Currently, traditional technologies are widely used but have limitations, while new technologies are emerging continuously, and combined processes have also developed. However, these technologies face problems such as high costs, poor stability, difficult sludge treatment, and insufficient water quality adaptability. In the future, the nitrogen and phosphorus removal technologies in wastewater treatment plants will develop towards technological innovation and optimization, intelligence and automation, resource recovery and sustainable development, and standardization and regulation construction, aiming to achieve the goals of efficient nitrogen and phosphorus removal, resource recovery, and the sustainable operation of wastewater treatment systems.
