摘要
目的掌握安阳市农村饮水安全工程水质卫生现状,为政府制定相关政策提供科学依据,以保障农村饮水安全。方法对204个农村饮水安全工程水质监测点进行枯水期和丰水期出厂水、末梢水的水样采集、保存和检验工作,并对检测结果进行评价、统计分析和对比。结果水质总体合格率为62%。枯水期和丰水期水质差异有统计学意义(P<0.05),且枯水期合格率大于丰水期合格率;枯水期和丰水期微生物学指标差异有统计学意义(P<0.05),且枯水期微生物学指标合格率大于丰水期;枯水期和丰水期肉眼可见物指标差异有统计学意义(P<0.05),且丰水期肉眼可见物指标合格率低于枯水期;枯水期和丰水期浑浊度指标差异有统计学意义(P<0.05),且枯水期浑浊度指标合格率高于丰水期。结论安阳市农村饮水安全工程水质总体合格率较低,主要影响指标包括微生物指标和浑浊度、肉眼可见物等感官性状指标,需要引起相关部门和村民的共同重视。应加强农村饮水安全工程管理,改善农村饮水卫生现况。
OBJECTIVE To acquire the water quality and sanitation status of rural drinking water safety project in Anyang,and provide scientific basis for the government formulating relevant policies to ensure the safety of rural drinking water.METHODS 204 water quality monitoring points of the rural drinking water safety project in Anyang in 2018 were used to collect,preserve and test water samples from the factory water and terminal water in low-water period and high-water period. The test results of water samples were evaluated,statis tically analyzed and compared.RESULTS The overall qualified rate of water quality was 62%. The difference between low-water period and high-water period were statistically significant(P <0.05),and the water quality pass rate in low-water period was higher than highwater period. The difference between microbial index in low-water period and high-water period were statistically significant(P <0.05), and the water quality pass rate of microbiological index in low-water period was higher than high-water period. There were statistically significant difference between the visible indicators in low-water period and high-water period(P <0.05),and the qualified rate of visi ble indicators in high-water period was lower than low-water period. There were statistically significant difference between the turbidity index in low-water period and high-water period(P <0.05),and the qualified rate of turbidity index in low-water period was higher than high-water period.CONCLUSION The overall qualified rate of water quality in the rural drinking water safety project in Anyang was low. The main impact indicators included microbiological indicators and sensory traits. It needed to draw the attention of relevant de partments and villagers,strengthen the management of rural drinking water safety projects,and improve the current situation of rural drinking water.
