Limited by the shortage of water resources, the utilization of water resources has become a solution, and seawater desalination is the undeveloped blue ocean. At present, technical improvement and development are the focus of the field of seawater desalination.
Recently, a research team from Harbin Institute of Technology reported to the outside world a new process for preparing ultra-high flux nanoporous graphene (NG) films. It is understood that it does not require the formation and transfer of synthetic pores, and has a good range of technical performance for continuous seawater desalination. Industry insiders speculate that the process or in the future desalination field to occupy a certain position.
In addition to this good news, all parties are actively promoting the maturity and development of seawater desalination field.
For example, a university research team developed a desalination system that increases the efficiency and reduces the cost of desalination. It is said that the system can also be used to treat polluted sewage or generate steam to sterilize medical instruments.
For example, the news that a tycoon in the field of science and technology investment linked to a "small" seawater desalination field related enterprises, visible desalination market road "a bright". From the present point of view, the expansion of the desalination market is not enough? Can only say, "is not not, but the time has not come."
Admittedly, the expansion of the seawater desalination market has not reached its peak, but we can see that the scale of the project is steadily expanding year by year. "2020 National Seawater utilization Report" shows that at the end of 2020, there are 135 seawater desalination projects in the country, with the project scale exceeding 1.65 million tons per day. Compared with the previous data, the development trend of seawater desalination is unchanged, and there is a steady rise. In addition, China's several coastal provinces and cities in part of the growth line in this field is more obvious.
With favorable geographical location, abundant rainfall and abundant sea water resources, coastal provinces such as Zhejiang and Shandong are always in urgent need of sea water resource reclamation.
In the 14th Five-year Plan of circular Economy development, Zhejiang province proposes to carry out seawater desalination demonstration projects and vigorously promote seawater desalination in island areas and coastal industrial parks. By 2025, the capacity of seawater desalination in the province will reach 550,000 cubic meters per day, promote seawater desalination projects, technology and equipment, and reduce the cost of seawater desalination.
Shandong province recently established the Shandong Seawater desalination Utilization Association, and plans to set up the "Shandong Seawater desalination industry development fund", a scale of 5 billion yuan, will support the province's seawater desalination projects, industrial chain and supporting equipment production. Shandong's commitment to desalination is also evident. In the "14th Five-year Plan for Ecological and Environmental Protection of Shandong Province" previously released, the goal of "actively promoting the utilization of seawater desalination in 7 coastal cities, and realizing the seawater desalination capacity of the whole province over 1 million tons/day by the end of 2022" has also become the guiding light for the development of seawater desalination in Shandong Province.
In addition to these large provinces of seawater desalination, it is worth mentioning that the members of this network, deep cultivation of seawater desalination enterprises are not a few. Shangtuo Environment, Lightrider, HONGda environmental protection and other enterprises are in their own way to provide strength and guarantee for the development of seawater desalination field.
A breakthrough is something to look forward to! How could the "future" of desalination not be highlighted?
