摘要
目的通过对北京市朝阳区农村地区生活饮用水水质进行综合评价与分析,为朝阳区农村地区生活饮用水质监测和管理提供科学依据。方法选取2017—2018年朝阳区农村地区自备井集中式供水的生活饮用水288件水样监测数据,运用水质综合指数评价法对水质进行评价和分析。结果 2017—2018年朝阳区农村自备井供水的生活饮用水的整体合格率为99.65%,平均水质综合指数为0.27±0.08。2017—2018年丰水期和枯水期的农村自备井水水样合格率分别为99.31%和100%;总水质综合指数分别为0.27±0.08和0.26±0.08,经非参数检验(Kruskal-Wallis检验),差异有统计学意义(χ~2=5.59,P<0.05)。结论 2017—2018年北京市朝阳区农村地区自备井供水的生活饮用水水质总体较好,主要受到枯丰水期的影响,应加强丰水期饮用水的水质监管。
Objectives To provide a scientific basis for monitoring and management of drinking water quality in rural areas of Chaoyang district by comprehensive evaluation and analysis of drinking water quality in rural areas of Chaoyang district of Beijing.Methods Totally 288 drinking water samples of centralized wells water supply in rural areas of Chaoyang district from 2017 to 2018 were collected,and their qualitie swere evaluated and analyzed by using water quality integrated index methods.Results The overall qualified rate of drinking water supplied by rural wells in Chaoyang district from2017 to 2018 was 99.65%,and the average water quality integrated index was 0.27±0.08.The qualified rate of water samples from rural self-drilled wells during the high-water season and dry season of2017 to 2018 were 99.31% and 100% respectively;the total water quality integrated index were 0.27±0.08 and 0.26±0.08,with statistically significant difference by Kruskal-Wallis test(χ~2=5.59,P<0.05).Conclusion From 2017 to 2018,the quality of drinking water supplied by self-drilled wells in rural areas of Chaoyang district of Beijing was generally good,and it was mainly affected by the dry season and high-water season.We should strengthen the supervision and surveillance of drinking water quality during the high-water season.
