摘 要:目的 研究去极化氧化还原电位(oxidation reduction potential, ORP)与游泳池水其他卫生指标间的关系, 探索如何按照卫生标准进行pH和ORP监测与自动调节系统的设计。方法采集游泳池水样品111份,分别对余氯、 水温、pH、浑浊度、尿素这5个指标和ORP进行秩相关分析。结果 余氯和ORP呈正相关;控制余氯不变,pH值和 ORP呈负相关;控制余氯不变,水温和ORP不存在线性相关关系;浑浊度和ORP不存在线性相关关系;尿素和ORP不 存在线性相关关系。结论在游泳池水质监测和自动调节系统设计中,建议按顺序调节,先调节水温、再调节pH值,当 水温和pH都调节合格后,如果ORP仍旧不足650 mV,再增加投氯量。Objective To probe into the correlation among the oxidation reduction potential and other hygienic indices of swimming pool water,and to explore the design of an automatic treatment system of pH and ORP for swimming pool water according to hygiene standards.Methods A total of 111 swimming pool water samples were collected.The indices included:ORP,free residual chlorine,pH,water temperature,urea and turbidity.Rank correlation was used.Results The free residual chlorine was positively correlated with ORP.The pH was in positive correlation with ORP when residual chlorine was controlled.No correlation between water temperature and ORP was found when residual chlorine was controlled.No correlation between turbidity and ORP,urea and ORP were found.Conclusion In the operation of the automatic treatment system of swimming pools water,the factors should be regulated sequentially:firstly water temperature,and followed by pH;if ORP stays below 650 mV,more chlorine should be applied.
