农村饮用水安全与水质卫生监测探究

Monitoring and Exploration the Safety and Sanitary Quality of the Village Drinking Water

目的探究农村饮用水安全与水质卫生监测结果。方法回顾性分析2013年1月—2015年9月该县疾病预防控制中心监测的272份农村生活饮用水水质监测数据,对比不同年份本市农村地区水质合格率,不同水期水质合格率以及不同年份水样监测感官性状指标与微生物指标监测超标率对比。结果该县2014年、2015年农村饮用水合格率依次为43.75%、25.00%,均显著低于2013年63.33%,其中属2015年农村饮用水合格率最低;并且丰水期水质监测合格率38.97%显著高于枯水期23.53%,对比差异均具有统计学意义(P<0.05)。结论近年来,该县农村地区生活饮用水总体合格率偏低,微生物指标超标较严重,相关部门应重视该问题,加大监管力度,加强饮用水消毒工作,为农村生活饮用水提供安全保障。

Objective To explore the safety and sanitary quality monitoring results of the village drinking water. Methods To retrospective analyse the 272 cases of the village drinking water quality monitoring data of our country from the January,2013 to the September, 2015. To compared with the qualification rate of the water quality in village of our city that in the different year, the qualification rate of the water quality during the different water period, and the water monitoring sensory properties index, microbiological index monitoring over-standard rate in the different year. Results The qualification rate of the village drinking water was 43.75% and 25.00% of our country in 2014 and 2015, that significantly lower than the63.33% in 2013. Among of them, the qualification rate of village drinking water was the lowest in 2015;The qualification rate of water quality monitoring was 38.97% at the high flow period, that significantly greater than the 25.53% at the low flow period.（P 0.05）. Conclusion For the past few years, the total qualification rate of the drinking water was on the low side at the rural area of our country, the microbiological index was exceeded seriously. The relevant departments should pay attention on this problem, to reinforce the supervision and the disinfection of drinking water. By this way, that provided the safety guarantee for the village drinking water.
