摘要/Abstract

摘要： 目的了解新疆供水系统中水pH值变化趋势及与其他水质参数间的关系。方法收集2020—2022年新疆维吾尔自治区87个监测单位对城乡各供水厂的水质监测数据,并对数据进行分析。结果 2020—2022年共监测18 656份水样,pH值[M（P₂₅,P₇₅）]为7.78（7.40,8.00）,总合格率为99.69%。2020—2022年pH值合格率呈逐年递增趋势（χ²_趋势=16.045,P<0.01）;不同采样类型下,城市饮用水与农村饮用水pH值比较,差异有统计学意义（χ²=14.213,P<0.05）。不同水源类型下,地表水水源饮用水与地下水水源饮用水pH值比较,差异有统计学意义（χ²=116.034,P<0.05）;总硬度（β=-0.101,P<0.01）、色度（β=-0.192,P<0.01）、氯化物（β=-0.069,P<0.01）显著负向预测水pH值,硫酸盐（β=0.106,P<0.01）显著正向预测水pH值。浑浊度和色度值与预测饮用水pH值合格的概率相关。结论 pH值与部分水质参数相关联,并可以反映水质情况。不同的水源类型中,水pH值与其他水质参数的关系不同,且会受到其他理化参数的影响。

Abstract: Objective To understand the trend of pH value changes in water supply system in Xinjiang and its relationship with other water quality parameters. Methods The water quality monitoring data of 87 monitoring units for urban and rural water supply plants in Xinjiang Uygur Autonomous Region from 2020 to 2022 were collected,and the data were analyzed. Results From 2020 to 2022,a total of 18 656 water samples were monitored,with pH values[M（P₂₅,P₇₅）] of 7.78（7.40,8.00） and the total qualified rate of 99.69%. The pH qualification rate showed an increasing trend year by year from 2020 to 2022（χ²=16.045,P<0.01）. There was a statistically significant difference in pH values between urban drinking water and rural drinking water under different sampling types（χ²=14.213,P<0.05）. There was a statistically significant difference in pH values between surface water source drinking water and groundwater source drinking water under different water source types（χ²=116.034,P<0.05）. The total hardness,chroma,and chloride significantly negatively predicted the pH value of water（β=-0.101,-0.192,-0.069,all P<0.01）,while sulfate significantly positively predicted the pH value of water（β=0.106,P<0.01）.Turbidity and chromaticity values were correlated with the probability of predicting the pH value of drinking water to be qualified. Conclusion pH value is associated with some water quality parameters and can reflect water quality situation. In different water source types,the relationship between water pH value and other water quality parameters is different,and it is affected by other physical and chemical parameters.
