摘　　要：用由不同电极材料制成的两种电解槽分别进行正交实验,考察了电解电压、电解质浓度、酸碱出水量比三因素对酸性氧化电位水各项指标的影响。结果表明:Ⅰ号槽(钛镀铂、铱电极),三种工艺对pH、ORP及有效氯影响的显著性顺序均为电解质浓度>电解电压>酸碱出水量比,最优工艺为,电解电压8.5 V,电解质浓度0.67 g/L,酸碱出水量比0.8∶1;水质指标为pH 2.26、ORP1185.7 mV、有效氯50.42 mg/L。Ⅱ号槽(钛镀铂电极),三种工艺对pH、ORP影响的显著性顺序为电解电压>电解质浓度>酸碱出水量比,而对有效氯影响最为显著的因素是电解质浓度,最优工艺为,电解电压8.5 V,电解质浓度1.11 g/L,酸碱出水量比0.8∶1;水质指标为pH 2.23、ORP1180.2 mV、有效氯41.66 mg/L。说明由于电解槽电极材料的不同,使得各因素对水质指标的影响有所差别。Two electrolysis rooms with different electrode materials （platinum ＆ iridium： Ⅰ , platinum： Ⅱ） were used in this experiment. Effects of voltage, electrolyte concentration and outflow scale （acid： alkali） on properties of electrolyzed oxidizing water （EOW） were investigated by orthogonal test. The results showed that the relative influence degree of the three technology factors was electrolyte concentration〉vohage〉outflow scale in the experiment of electrolysis room Ⅰ. The optimum production conditions of EOW were voltage 8.5 V, electrolyte concentration 0.67 g/L and outflow scale 0.8 ： 1. The indexes of EOW were pH 9.34, ORP 1185.7 and available chlorine 50.42 mg/L. In the experiment of electrolysis room Ⅱ, the relative influence extent on pH and ORP was voltage〉electrolyte concentration 〉outflDw scale. However, it was the electrolyte concentration that had significant influence on available chlorine content. The optimum production conditions were voltage 8.5 V, electrolyte concentration 1.11 g/L and outflow scale 0.8 ： 1. The indexes of EOW were pH2.23, ORP 1180.2 mV and available chlorine 41.66 mg/L. Influence degree of the three technology＇factors on properties of EOW made a difference, which might result from the use of different electrode materials in the two electrolysis rooms.
