磁场对含Ni废水混凝的影响

The Effect of Magnetic Field on the Coagulation of Ni-Contained Wastewater

对不溶性强磁性水污染物、高梯度磁处理技术已显示了其速度快、效率高、成本低等优点,并受到人们的注目,但对于弱磁性悬浮物及可溶性磁性物质来说,目前所采用的加磁种的方法,因其工艺复杂、成本高而无法推广,如何选择合理的处理方法,是废水磁分离技术的一个重要研究课题,磁场作为混凝的强化手段,国外已有一些研究,但国内尚未见报道,本文研究了非均匀磁场对含Ni废水混凝处理的影响及相关的各种因素。

The effect of magnetic field on the treatment of Ni-contained wastewater was studied. It is found that the magnetic treatment can intensify the process of coagulation and sedimentation of wastewater. The intensification is relative to the treatment method, field strength and treating time in the magnetic field.
