Sea sand desalination treatment technique and system
The present invention discloses a sea sand desalination treatment technique. The treatment technique comprises the steps of a) immersing sea sand into a dechlorinating agent to perform dechlorination of the sea sand; b) separating the sea sand from the dechlorinating agent solution; and c) heating the dechlorinated sea sand. Besides, the present invention further discloses a sea sand desalination system. According to the present invention, ozonated water or a sodium persulfate acidic solution is used to perform dechlorination on the sea sand, wherein a chemical reaction occurs in the dechlorination process and chloride ions turn to chlorine gas; the sea sand is separated from the dechlorinating agent solution; and the chlorine gas remained on the surface of the sea sand is vaporized after heating, thereby preventing the chlorine gas from causing damage to the human body in the process of sea sand utilization and meanwhile achieving a dechlorination effect. The present invention can achieve the dechlorination effect simply by using the ozonated water or the sodium persulfate acidic solution, and compared with the effect and cost of dechlorination by rinsing with fresh water, the effect of desalination by using the dechlorinating agent is better and the cost of desalination is lower.
