目的研究比较游泳池水质自动监测和人工监测结果,为探索水质自动监测技术在游泳池场所中的应用提供依据。方法利用自动监测设备检测游泳池水水温、游离性余氯、浑浊度和p H值,用人工监测作为对照,比较2种方法监测结果的一致性。结果 2种方法监测游泳池水水温、余氯、浑浊度和p H值的相关系数分别为0.644、0.940、0.423和0.451(P<0.001),p H值监测结果的最大误差分别为-0.86、-0.05、0.02和-0.07,浑浊度相对误差绝对值均值分别为35.5%、2.2%、7.3%和11.2%。通过两样本非参数检验分析水温和余氯的监测结果,发现自动监测和人工监测方法对游泳池水的监测结果比较,差异无统计学意义(Z_(水温)=-0.562,P_(水温)=0.574>0.05;Z_(余氯)=-1.487,P_(余氯)=0.137>0.05)。结论自动监测与人工监测游泳池水质结果比较,数据的一致性好。
Objective To compare and analyze the results of automatic monitoring and manual monitoring of swimming pool water quality and provide the basis for exploring the application of automatic monitoring technology in swimming pool. Methods The water temperature, free residual chlorine, turbidity and p H values of swimming pool water were detected by automatic monitoring equipment. The monitoring results were compared by manual monitoring. Results The correlation coefficients of water temperature, residual chlorine, turbidity and p H of the two methods were 0.644, 0.940, 0.43 and 0.451 respectively (P <0.001). The maximum error of p H value was -0.86, 0.05, 0.02 and -0.07, and the relative mean relative errors of turbidity were 35.5%, 2.2%, 7.3% and 11.2%, respectively. Through the two samples non-parametric test and analysis of water temperature and residual chlorine monitoring results, found that automatic monitoring and manual monitoring methods for the comparison of the monitoring results of swimming pool water, the difference was not statistically significant (Z_ (water temperature) = -0.562, P_ (water temperature) = 0.574 > 0.05; Z_ (residual chlorine) = -1.487, P_ (residual chlorine) = 0.137> 0.05). Conclusion The results of automatic monitoring and manual monitoring of swimming pool water quality comparison, the data consistency.
