2018—2020年河北省农村饮用水水质分析

Analysis of drinking water quality in rural areas of Hebei Province, China, 2018—2020

摘要

摘要:
目的了解2018—2020年河北省农村饮用水水质卫生现状，为进一步解决农村饮用水卫生安全问题提供数据支撑。
方法 2018—2020年对河北省农村地区开展水质卫生监测，按照《生活饮用水卫生标准》（GB 5749-2006）对水质常规指标及氨氮结果进行分析评价。
结果 2018—2020年河北省农村饮用水总体达标率由高到低依次为2020年（81.38%）、2019年（68.21%）和2018年（65.23%），差异有统计学意义（χ²=754.69，P < 0.01）。主要未达标指标为氟化物，其次为总大肠菌群、硝酸盐、菌落总数、总硬度、氯化物、溶解性总固体和硫酸盐。氟化物超标主要在河北省东南部。
结论 2018—2020年河北省农村饮用水水质达标率逐年增高，氟化物和微生物指标为主要影响因素。

Abstract:
Objective To investigate the current status of drinking water quality in rural areas of Hebei Province in China from 2018 to 2020, and to provide data support for further solving the issues of rural drinking water safety.
Methods Water quality monitoring was conducted in rural areas of Hebei Province from 2018 to 2020, and the results of water quality routine indicators and ammonia-nitrogen were assessed according to the Standards for Drinking Water Quality (GB 5749-2006).
Results From 2018 to 2020, the overall qualified rates of rural drinking water in Hebei Province from high to low were 81.38% in 2020, 68.21% in 2019, and 65.23% in 2018, with a significant difference among the years (χ²=754.69, P < 0.01). The main unqualified indicator was fluoride, followed by total coliforms, nitrate, total numbers of colony, total hardness, chloride, total dissolved solids and sulfate. Excess fluoride content was mainly observed in the southeast of Hebei Province.
Conclusion There is a gradual increase in the qualified rates for rural drinking water quality in Hebei Province from 2018 to 2020. Fluoride and microbiological indicators were the main influencing factors.
