2015-2019年济阳区城乡生活饮用水水质监测结果分析

Analysis of Urban and Rural Drinking Water Quality Monitoring Results in Jiyang District from 2015 to 2019

目的:分析2015-2019年济阳区城乡饮用水水质状况,分析及总结影响生活饮用水水质的相关影响因素,从而提出针对性的改善对策。方法:对2015-2019年济阳区城乡生活饮用水水质进行采样、检测与分析。结果:2015-2019年济阳区城乡生活饮用水共监测水样352份,其中合格水样118份,总合格率为33.52%。2015-2018年济阳区城乡生活饮用水合格率分别为12.50%、10.71%、16.67%、41.43%,差异有统计学意义(P<0.05),2019年度合格率为100%;不同年份感官性状和一般化学指标、毒理学指标合格率、微生物指标合格率间比较(P<0.05);感官性状和一般化学指标明显低于毒理学指标合格率和微生物指标合格率(P<0.05)。结论:影响水质超标的原因主要与制水工艺不完善和不采取消毒处理方式有关。

Objective: To analyze the urban and rural drinking water quality in Jiyang district from 2015 to 2019, and analyze and summarize the relevant infl uencing factors affecting domestic drinking water quality, so as to put forward targeted improvement countermeasures. Methods: The drinking water quality in urban and rural areas in Jiyang district from 2015 to 2019 is sampled, tested and analyzed. Results: From 2015 to 2019, 352 urban and rural drinking water samples are monitored in Jiyang district, including 118 qualified water samples, with a total qualified rate of 33.52%. From 2015 to 2018, the qualified rate of urban and rural drinking water in Jiyang district is 12.50%, 10.71%, 16.67% and 41.43%respectively, significant(P<0.05), and in 2019, the qualified rate is 100%, between sensory traits and microbial indicators(P<0.05), and general chemical indexes are significantly lower than that of toxicology and microbial indicators(P <0.05).Conclusion: The reasons affecting the excessive water quality are mainly related to the imperfect water production process and no disinfection treatment.
