摘要: 为精确控制EOW的出水水质,以商用的CTRO-60A型电解槽进行动态制水,考察电解质浓度c(NaCl)、电压U和电解时间t对出水关键指标ACC的影响。结果表明,在c(NaCl)=5.0~9.0 g·L-1、U=3.0~8.0 V及t=2.0~6.0 s,出水ACC与c(NaCl)和t线性相关,与U指数相关。并依此建立模型,为:ACC= 2.753e0.1888U c(NaCl)t- 36.82te-0.2152U -37.23 c(NaCl)e-0.5124U+87.24e-0.05856U (R2=0.994 5, α<0.001)。该模型对ACC的预测值与实测值的平均相对误差仅为2.45%。可用于EOW的自控系统,能精确控制出水水质。同时由于没有这类模型的相关报道,因此该模型可以为同类模型的建立提供参考。

Abstract: To control the quality of electrolyzed oxidizing water (EOW), the effects of electrolyte concentration (c(NaCl)), voltage (U) and electrolytic time (t) on available chlorine concentration (ACC) of electrolyzed oxidizing water were investigated. The results showed that when c(NaCl),U and t were in the range of 5.0~9.0 g·L-1, 3.0V~8.0 V and 2.0~6.0 s, respectively, ACC had linear correlation with c(NaCl) and t, and exponential correlation with U. The mathematic model was built up by these relations. It was ACC = 2.753e0.1888U c(NaCl)t- 36.82te-0.2152U- 37.23 c(NaCl)e-0.5124U+ 87.24e-0.05856U (R2=0.9945,α<0.001). This mathematic model could estimate the ACC with average relative error of 2.45%. It was useful for EOW automatic control system and the control of water quality.
