影响电解生成酸性电位水特性的因素

EFFECT OF PRODUCING CONDITIONS ON THE PROPERTIES OF ELECTROLYZED-OXIDIXING WATER

目的探讨不同生产条件对酸性电位水主要特性的影响。方法采用某公司生产的TS-3型电解水生成器,通过改变进水盐度（2 g·L^-1、10 g·L^-1）、进水速率（14、12、10、8、6、4、2、1、0.5 mL·s^-1）、进水温度（20、25、30、35、40℃）等条件,研究其与酸性电位水主要参数的关系。结果（1）增加进入盐度与降低进水速率均可增加氧化还原电位水的ORP值与有效氯含量,但当达到一定程度后,ORP值与有效氯含量增加缓慢;（2）当进水温度从20℃增到40℃,酸性电位水的ORP值降低约10 mV;（3）氧化还原电位水的ORP值与有效氯含量及pH值有关,当pH值在3.0以下及有效氯在1～2 mg·L^-1时,电解水的ORP值在1 000～1 100 mV左右,随pH值的进一步降低或有效氯的进一步增加,电解水ORP值增加缓慢。结论对于一定功效的电解器,采用一定的进水含盐度,控制一定的进水速率有助于高效、经济地生产出酸性电位水。

Objective To investigate the effect of producing conditions on the main properties of electrolyzed-oxidizing water.Methods The TS-3 electrolyzed-oxidizing water generator was used to generate electrolyzed-oxidizing water under various conditions such as water flow rates（14,12,10,8,6,4,2,1,0.5 mL·s^-1）,water salinities（2,10 g·L^-1） and temperatures（20,25,30,35,40 ℃） to analyze their relationship with the main properties of the electrolyzed-oxidizing water.Results（1） The ORP value and effective chlorine content of the produced electrolyzed-oxidizing water increased with decreasing water flow rate and/or increasing source water salinity.The increase in the two parameters became slow when the decrease in flow rate and the increase in salinity reached to some extent.（2） The ORP value of the electrolyzed-oxidizing water decreased by about 10 mV with increasing the source water temperatures from 20 to 40 ℃.（3） The ORP value of the electrolyzed-oxidizing water had a close relationship with its effective chlorine content and pH value.When the pH value was less than 3.0 and the effective chlorine content more than 1～2 mg·L^-1,the ORP value was 1 000～1 100 mV,but it increased slowly as further decrease in pH or increase in effective chlorine.Conclusion For an electrolyzed-oxidizing water generator with a fixed power,a definite range of source water salinity and flow rate are the necessary condition to generate effectively and economically electrolyzed-oxidizing water.
