【摘要】 介绍了稀土生产工艺及稀土废水来源及处理方法,并提出一种稀土废水处理及循环利用工艺,该工艺通过对各工艺废水采取分类回收、综合处理、以废治废等措施处理,经处理后废水水质可达国家排放标准,可在稀土工艺中循环使用,废水中有用物质经过回收用于生产工艺或外销。该工艺对稀土企业处理废水具有借鉴意义。更多还原

【Abstract】 The production technology of race earth,the source and processing method of race earth wastewater are introduced,a processing and cyclic utilization of race earth wastewater is proposed. The technology features as sorting and recycling,disposing universal,waste materials utilization in process. After disposing,the wastewater quality fulfills emission standard of national regulation,the waste water can go back to race earth production. The availing matter in wastewater by reclaiming can be reused to production or sold. The technology should be a reference to wastewater treatment of race earth enterprizes.更多还原
