摘要
构建泳池水循环系统以模拟现场余氯监测,以哈希便携式余氯仪的测量值为基准,比较恒压式余氯传感器、隔膜式余氯传感器和DPD比色法在线监测仪的测量结果,找出最适合应用于泳池水余氯在线监测的仪表,并研究了导致3种余氯在线监测仪测量结果差异性的因素。结果表明,DPD比色法在线监测仪在测量准确性及稳定性上表现最好,最适合应用于泳池水余氯在线监测。泳池水中存在的结合氯引起恒压式余氯传感器测量结果偏高,水样高浊度引起隔膜式余氯传感器的测量稳定性变差。
Building a swimming pool water circulation system to simulate on-site residual chlorine monitoring.Comparison of the results from the constant voltage chlorine sensor,diaphragm chlorine sensor,and analyzer of DPD photometry is carried out based on the test results from HACH detector,to find the most suitable analyzer for online monitoring of residual chlorine in swimming pool water.And researching on the factors that lead to differences in test results from three analyzers.The results show that the analyzer of DPD photometry which is most suitable for online monitoring of residual chlorine in swimming pool water performs the best in terms of test accuracy and stability.The combined chlorine in swimming pool water caused higher test results from constant voltage chlorine sensor,and high turbidity of water caused more poor stability of diaphragm chlorine sensor.
