摘　　要：利用复极连续式电生功能水生成系统,研究了不同操作条件(电压、盐酸溶液供给量、原水pH值和盐酸溶液质量分数)对电生功能水中有效氯浓度、pH值及电导率的影响。实验结果表明,微酸性电生功能水中的有效氯浓度随电压(3～5 V)的增大而增大(P<0.01),但pH值和电导率的变化不显著(P>0.05);随着盐酸溶液供给量增加,微酸性电生功能水中的有效氯浓度和电导率也随之增加,而pH值随之降低(P<0.01);随着原水的pH值升高,微酸性电生功能水的pH值升高而电导率减小(P<0.01),有效氯浓度变化不显著(P>0.05);微酸性电生功能水随盐酸溶液质量分数的增加,有效氯浓度和电导率随之增加,而pH值随之降低(P<0.01)。The effects of the different operation conditions such as the voltage supplied to the electrodes, the flux of the hydrochloric acid solution, the pH value of the raw water and hydrochloric acid solution concentration on the available chlorine content, the pH value and the electrical conductivity of the slightly acidic electrolyzed functional water （SAEFW） were investigated with a continuous electrolyzed functional water generating system which was independently developed. The results showed that the available chlorine concentration of the SAEFW increased significantly with the increase in the voltage in the range of 3 - 5 V （ P 〈 0.01 ） , but the influences of the voltage on the pH value and the electrical conductivity of the SAEFW were not noticeable （ P 〉 0.05）. It was also found that the available chlorine and the electrical conductivity of the SAEFW also increased significantly with the increase in the flux of the hydrochloric acid, solution, but the pH value of the SAEFW decreased obviously when the flux of the hydrochloric acid solution increased （P 〈 0.01 ）. In addition, as the pH value of the raw water rose, the pH value and the electrical conductivity of the SAEFW increased and decreased significantly, respectively （P〈0.01）. However, the effect of the pH value of the raw water on the available chlorine of the SAEFW was not significantly different （P 〉 0.05）. At last, the available chlorine concentration and electrical conductivity of the SAEFW increased with the increase of the hydrochloric acid solution concentration, on the contrary, the pH value decreased （P 〈 0.01 ）.
