采用被各大稀土厂堆积待用的中重稀土做沉淀剂 ,有效地降低了废水中的F- ,生产出了合格的稀土氟化物 ,使处理后的水质达到了工业用水标准 ,这样既节约了短缺的水资源 。
The heavy rare earth is used as the precipitating agent to treat the fluoridecontained acid wastewater,thus effectively decreases F - in the wastewater and the qualified rare earth fluoride is produced.The quality of the water after being treated meets the standard of industrial water supply.In this way,the water resource is saved and the living environment at the downstream of the drainage area and the area around the factory is properly protected.
