2019—2023年惠州市惠阳区城乡生活饮用水水质监测分析

Monitoring and Analysis of Urban and Rural Drinking Water Quality in Huiyang District,Huizhou City from 2019 to 2023

目的:分析惠州市惠阳区城乡生活饮用水水质存在的问题,并对水质存在问题提出针对性改善建议,为加强惠州市惠阳区城乡生活饮用水卫生管理提供技术支持。方法:按照GB/T 5750.1—2006到GB/T 5750.13—2006及GB/T 5750.1—2023到GB/T 5750.13—2023进行水样检测,结果参照《生活饮用水卫生标准》(GB 5749—2006)及《生活饮用水卫生标准》(GB 5749—2022)进行卫生评价。结果:2019—2023年惠阳区城乡生活饮用水的水质总体合格率为90.09%,枯水期合格率为91.75%,丰水期合格率为88.61%,枯水期比丰水期水质合格率高。不同类型水样合格率差异无统计学意义(χ^(2)=0.613,P>0.05)。城区的水质合格率比乡镇高。水质合格率最低项目为肉眼可见物(98.41%),其次为浑浊度(98.68%)。结论:惠州市惠阳区城乡生活饮用水水质合格率相对较高,但仍有不合格项目指标,需加大监督及检测力度,重点加强乡镇饮水管理,提高乡镇的水质合格率。

Objective:To analyze the problems of urban and rural drinking water quality in Huiyang district of Huizhou city,and put forward suggestions for the improvement of water quality problems,so as to provide technical support for strengthening urban and rural drinking water sanitation management.Method:Water samples were detected according to GB/T 5750.1—2006 to GB/T 5750.13—2006 and GB/T 5750.1—2023 to GB/T 5750.1—2023.Result:The overall qualified rate of urban and rural drinking water quality in Huiyang district from 2019 to 2023 was 90.09%,91.75% in dry season and 88.61% in wet season,and the qualified rate in dry season was higher than that in wet season.There was no significant difference in the qualified rate of different types of water samples (χ~2=0.613,P>0.05).The qualified rate of water quality in urban area is higher than that in township.The lowest qualified rate of water quality was visible matter (98.41%),followed by turbidity (98.68%).Conclusion:The qualified rate of urban and rural drinking water quality in Huiyang district of Huizhou city is relatively high,but there are still unqualified project indicators.It is necessary to strengthen supervision and testing,focus on strengthening drinking water management in towns and villages,and improve the qualified rate of water quality in towns and cities.
