酸性氧化电位水制备新工艺

A new way to prepare electrolyzed oxidizing water

对EOW制备工艺中离子膜类型、电解方式和碱性水回流3个方面进行了考察，发现利用均相阴离子交换膜代替均相阳离子交换膜，可以有效地提高电解效率，原因在于阴离子膜可以有效地阻止H^＋的反渗透；采用阴、阳电解槽同时加入电解质溶液并采用阴离子膜的电解方式最优；当回流比在40％～60％时可以得到合格的EOW，回流比为80％时得到EOW的pH值超出范围；回流比对EOW的ORP值和ACC值影响不大。设计了EOW制备的新工艺，提高了制备效率和电极使用寿命，减少了碱性水的排放。

The effects of ion membrane types, the electrolyticways and electrolyzed reductive water＇ s（ERW） reflux on the preparation technology of electrolyzed oxidizing water（EOW） are investigated. The results show that：（1）the electrolyticefficiency can be enhanced using anion exchange membrane instead of cation exchange membrane because the former one can effectively prevent hydrogen ion from permeating into cation cell; （2）the best way of electrolytic is that both cells are electrolytic solution and anion exchange membrane is used; （3）the eligible EOW can be obtained under the reflux ratio of 40% - 60%, and the value of pH will be out of range when the reflux ratio is above 80%. The effects of different reflux ratio on the value of oxidation reductive potential（ORP） and available chlorine content（ACC） are very little. A new preparing process is designed, which can not only enhance electrolytic efficiency and electrode lifetime, but also can decrease ERW discharge.
