Realizing efficient control of water pollution and green utilization of water resources is a necessary condition for maintaining public health, promoting ecological civilization construction, and promoting sustainable economic and social development. This study reviews and summarizes the global scientific and technological research hotspots in this field in 2023,with highlights on prevention and control of new pollutants in surface water, protection of groundwater resources, safety assurance of drinking water, carbon reduction and efficiency enhancement in sewage treatment, resource utilization of wastewater,development of unconventional water sources, and protection and utilization of water resources in China. Research shows that construction of a new pollution prevention and control system for surface water should focus on the research of environmental quality standards and pollution control technologies. It is expected to improve the protection level of groundwater resources with the help of modern hydrogeology. New membrane technology helps ensure drinking water safety, and the synergistic development of efficiency and carbon reduction has become a new challenge for the sewage treatment industry. In the field of rural sewage treatment and resource utilization, substantial achievements and research results have been made in multiple aspects such as technological innovation, management optimization, and sewage resource utilization. Carbon based nanomaterials and other materials have received widespread attention in the field of environmental radioactive nuclide separation. Crystallization technology is a key technology for zero discharge of high salinity wastewater. New membrane distillation technology can promote the steady development of seawater desalination technology and engineering construction. All these research results have important meanings to the major strategic engineering practices of water resource protection and utilization, as well as water pollution control.
