| description | The invention belongs to the technical field of seawater development, and particularly relates to a seawater comprehensive utilization process system, which is characterized in that seawater passes through a bromine extraction system, a sodium extraction system, a potassium extraction system and a magnesium extraction system for extraction of various chemical elements, and comprises the following steps: A, the bromine extraction system is used for obtaining sodium bromide through brine preparation; and oxidizing sodium bromide into elemental bromine through sulfur dioxide and chlorine. According to the process system, zero discharge of seawater and full utilization of seawater resources are achieved, bromine products, sodium products, potassium products and magnesium products with high additional values are prepared in sequence, the whole process is complementary in the front-back direction and makes the best use of materials, good economical efficiency is achieved, seawater is comprehensively utilized in the |
