摘要:

目的 了解2015—2023年成都市某区居民生活饮用水水质状况,分析影响该区饮用水水质状况的因素。方法 2015—2023年采集不同时期的城市和农村生活饮用水进行实验室检测,并分析影响水样合格率的风险因素。结果 2015—2023年该区生活饮用水合格率呈逐年上升趋势,从2015年的72.83%上升到2023年的100.00%(P<0.05)。枯水期水样合格率高于丰水期(χ2=8.003,P<0.05);江河水的合格率高于湖泊水、水库水、浅井水及深井水(P<0.05);城市水的合格率高于农村水(χ2=31.166,P<0.05),使用次氯酸钠消毒的水样合格率最高(P<0.05);经过常规处理的水样合格率高于机器取水和人工取水(P<0.05)。供水处理方式为机器取水(OR=187.662,95%CI:24.721~1 424.589)是水样不合格最大的危险因素;水源类型为江河水(OR=0.031,95%CI:0.009~0.103)是水样不合格最大的保护因素。结论 2015—2023年间该区生活饮用水水质状况不断改善,但仍需加强枯水期农村地区水质监测,消毒剂指标和消毒副产物指标应重点关注。

Abstract:

Objective To understand the sanitary status of drinking water quality for residents in a district of Chengdu from 2015 to 2023,and analyze the factors affecting the quality of drinking water in this district. Methods Domestic drinking water samples from urban and rural areas were collected in different periods for laboratory testing,and the risk factors influencing the water sample qualification rate were analyzed. Results The qualified rate of domestic drinking water in the district increased year by year from 2015 to 2023,from 72.83% in 2015 to 100.00% in 2023(P<0.05). The pass rate of water samples in dry season was higher than that of wet season(χ2=8.003,P<0.05),and that of river water was higher than that of lake water,reservoir water,shallow well water and deep well water(all P<0.05).The pass rate of urban water was higher than that of rural water(χ2=31.166,P<0.05),and that of water samples disinfected with sodium hypochlorite was the highest(P<0.05). The pass rate of water samples treated by conventional treatment was higher than that of machine water and manual water intake(both P<0.05). Machine water intake(OR=187.662,95%CI:24.721-1 424.589) was the biggest risk factor for unqualified water samples,and the water source type of river water(OR=0.031,95%CI:0.009-0.103) was the biggest protective factor for unqualified water samples. Conclusion From 2015 to 2023,the quality of drinking water in this area has been continuously improved,but it is still necessary to continuously strengthen the monitoring of rural water quality during the dry season,and the indicators of disinfectants and disinfection by-products should be paid more attention to.
