2017至2019年江西省农村生活饮用水浑浊度影响因素分析

Analysis on influencing factors of turbidity of rural drinking water in Jiangxi Province from 2017 to 2019

目的分析江西省农村生活饮用水浑浊度的影响因素。方法选取2017至2019年连续进行农村生活饮用水水质监测的71个项目县(市、区),收集水质浑浊度监测数据,采用多因素Logistic回归分析农村生活饮用水浑浊度的影响因素。结果2017至2019年共检测水样19435份,浑浊度的总合格率为95.88%。在不同水期、水源、工程规模、水处理工艺、管网使用时间浑浊度合格率比较差异有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,水期类型、水源类型、工程规模、水处理工艺、管网使用时间均为影响水质浑浊度合格的因素(P<0.05)。结论江西省农村生活饮用水水质浑浊度与水期类型、水源类型、水处理方式、工程规模和管网使用时间有关。

Objective To analyze the influencing factors of turbidity in rural drinking water in Jiangxi Province.Methods 71 counties(cities and districts)were selected for continuous monitoring of rural drinking water quality from 2017 to 2019,the monitoring data of turbidity were collected,multivariate Logistic regression was used to analyze the influencing factors of rural drinking water turbidity.Results 19435 samples were collected between 2017 to 2019.the total qualified rate of turbidity was 95.88%.There were differences in the qualified rate of turbidity in different water period,water source,project scale,water treatment process and pipe network service time(P<0.05).Multivariate Logistic regression analysis showed that water period type,water source type,project scale,water treatment process and pipe network service time were the factors affecting the qualified water turbidity.Conclusion The turbidity of rural drinking water quality in Jiangxi Province is related water period type,water source type,water treatment mode,project scale and service time of pipe network.
