硝酸肼镍废水的处理和回收利用
The Treatment and Reclaim Utilization of the Waste Water of Nickel Hydrazine Nitrate
摘要:
介绍了用母液循环、分解、沉淀分离等方法处理和回收利用硝酸肼镍废水。实践证明:利用“母液循环”工艺制备硝酸肼镍可大量减少废水产生、节约水量,并且能提高产品质量;利用分解、沉淀分离的方法可回收硝酸镍,处理后的废水符合国家规定排放标准。
Abstract:
This paper introduces using the methods of liquor cycle, decomposition, precipitation, separation to treat and recycle the waste water of nickle hydrazine nitrate. Practice proved that: using the technology of liquor cycle to prepare the nickle hydrazine nitrate can greatly reduce waste water generation, conserve water and improve product quality; the use of decomposition and precipita-tion separation could recover nickle nitrate and the treated waste water is in line with the nation emission standards.
