电极棒在污水回用反渗透装置上的应用研究

ON APPLICATION OF ELECTRODE ROD IN REVERSE OSMOSIS DEVICE FOR WASTE-WATER REUSE

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。

By using high-voltage discharge technology and capacitance effect,the electrode rod can make col-loidal particles in water increase the particle potential instantly,increase the surface charge density,and im-prove the mutual repulsion between particles in water.This can prolong the operation cycle of reverse osmosis membrane device and improve the production efficien-cy.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 peri-od,the RO with electrode rod produces 19.65%more reuse water than that without electrode rod.
