Recovery treatment method of high-salt mineralization water

The invention discloses a recovery treatment method of high-salt mineralization water. The method comprises the following steps: adding an impurity removal agent and a settling agent into high-salt mineralized water to remove solid suspension and part of metal impurities in the sewage, adjusting the pH value to recover magnesium salt, removing the magnesium salt, adjusting the pH value, and introducing carbon dioxide to generate calcium carbonate to recover calcium salt. The problem that calcium and magnesium ions in the water body are simultaneously precipitated and cannot be separated to cause waste of calcium and magnesium resources when a lime softening method is used for treating the high-hardness water body is solved, and comprehensive utilization of resources is achieved. 本发明公开了一种高盐矿化水的回收处理方法。首先将高盐矿化水通过投加除杂剂和沉剂以去除污水中的固体悬浮、部分金属杂质，然后调节pH值回收镁盐，去除镁盐后再调节pH值通入二氧化碳生成碳酸钙的形式回收钙盐，解决石灰软化法处理高硬度水体会造成水体中的钙镁离子同时沉淀、无法分离导致钙镁资源浪费的问题，达到资源的综合利用。
