Deep dechlorination sand washing method for sea sand desalination
The invention relates to the technical field of sea sand desalination, in particular to a deep dechlorination sand washing method for sea sand desalination. The method comprises the following operation steps: 1, washing with clear water; 2, performing deep dechlorination; 3, recycling fine sand; 4, performing tail water purification; 5, detecting chloride ions. According to the invention, the chloride deposition layer on the surface of the sea sand can be deeply removed, so that each index of the desalted sea sand can reach the national first-class building sand standard; in the whole sea sand desalination construction process, no chemical agent needs to be added, and secondary pollution to the environment cannot be caused; and tail water is purified and discharged after reaching the standard.
本发明涉及海砂淡化技术领域，具体为一种用于海砂淡化的深层除氯洗砂方法，包括如下操作步骤：步骤一：清水冲洗；步骤二：深层除氯；步骤三：细砂回收；步骤四：尾水净化；步骤五：氯离子检测。本发明可对海砂表面的氯化物沉积层进行深层去除，使淡化后的海砂各项指标均能达到国家一类建筑用砂标准；本发明在海砂淡化施工全过程中，不需要添加任何化学药剂，不会对环境造成二次污染；尾水净化达标排放。
