Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a design method of a seawater desalination membrane based on a neural network. Background technique [0002] The earth has 71% of the ocean area, seawater resources are the precious wealth brought to us by nature. Some coastal areas and islands are economically developed, but freshwater resources are relatively insufficient. Although seawater contains many elements that are beneficial to the human body, most of the concentration is too high, direct drinking will damage human health, and unpurified seawater also contains a lot of harmful substances. At the same time, too much salt in seawater will damage the machine and affect the service life of the machine. Desalination can solve the problem of shortage of fresh water resources. [0003] At present, seawater desalination technology is widely used in many fields, especially reverse osmosis seawater desalination technology ...
