摘要: 电极棒利用高压放电技术及电容效应,可以使水中胶体粒子瞬间提升粒子电位,增加表 面电荷密度,同时提高水中粒子与粒子间的互斥力,从而延长反渗透膜装置运行周期,提高生产效率。 在异常运行期,安装电极棒的反渗透比不安装电极棒的反渗透运行时间延长1 倍;在平稳运行期间, 安装电极棒的反渗透比不安装电极棒的反渗透多产19.65% 的回用水。

Abstract: By using high-voltage discharge technology and capacitance effect, the electrode rod can make colloidal particles in water increase the particle potential instantly, increase the surface charge density, and improve the mutual repulsion between particles in water. This can prolong the operation cycle of reverse osmosis membrane device and improve the production efficiency. During the abnormal operation period, the operation time of RO with electrode rod is twice longer than that without electrode rod; during the stable operation period, the RO with electrode rod produces 19.65% more reuse water than that without electrode rod.

Key words: electrode rod, reverse osmosis (RO) device, wastewater reuse
