Abstract:
(EN) A method for treating waste water from a spherical nickel hydroxide production process, which uses a combined membrane treatment process to systematically and targetedly treat processing waste liquid that is produced during each stage of a spherical nickel hydroxide preparation process; a waste water stock solution is concentrated so as to reduce the processing load in an evaporation process, thus reducing energy consumption while having significant environmental benefits; in addition, the membrane treatment system is easy to control and simple to operate and may enable the quality of water from a water production section to reach the standard of purified water.
(FR) Un procédé de traitement d'eaux usées issues d'un procédé de production d'hydroxyde de nickel sphérique qui utilise un procédé de traitement à membrane combiné pour traiter systématiquement et de manière ciblée les déchets liquides de traitement produits à chaque étape d'un procédé de préparation d'hydroxyde de nickel sphérique; une solution de réserve d'eaux usées est concentrée de façon à diminuer la charge de traitement dans un processus d'évaporation, réduisant ainsi la consommation d'énergie tout en possédant des avantages environnementaux significatifs; en outre, le système de traitement à membrane est facile à commander, simple à utiliser et peut permettre à la qualité d'une section de production d'eau d'atteindre le niveau d'eau purifiée.
(ZH) 一种球形氢氧化镍生产工艺过程废水的处理方法,采用组合的膜处理工艺,系统且有针对性地处理球形氢氧化镍制备过程中各个阶段产生的过程废液,将废水原液进行提浓处理,降低了蒸发工艺的处理量,降低能耗,环保效益明显,同时膜处理系统具有易于控制、操作简单,可以将产水部分水质达到纯水的标准。
