摘要
目的了解黄山市2018年农村生活饮用水卫生现状,为提高农村生活饮用水卫生质量提供科学依据。方法按照GB/T 5750-2006《生活饮用水标准检验方法》于2018年对530份农村生活饮用水进行采样检测,并按GB 5749-2006《生活饮用水卫生标准》对检测结果进行评价。结果 2018年共监测水样530份,合格338份,合格率为73.2%;以地面水、地下水为水源的水样合格率分别为77.7%和71.6%,差异有统计学意义(χ~2=10.100,P<0.05);检测指标中,游离余氯、二氧化氯、总大肠菌群合格率最低,分别为63.2%、76.8%、73.2%。结论黄山市农村饮用水以地下水为水源的水质合格率显著高于以地面水为水源的水质合格率,影响农村生活饮用水水质合格率的主要因素是消毒剂指标和微生物指标,加强监督管理和规范饮水安全工程建设是提高农村生活饮用水卫生质量的有效途径。
Objective To understand the current situation of rural drinking water sanitation in Huangshan City in 2018,provide scientific basis for improving the quality of rural drinking water. Methods 530 samples of rural drinking water were samples and tested according to the "Standard examination methods for drinking water"(GB/T 5750-2006),and the test results were evaluated according to the "drinking water health standards"(GB 5749-2006). Results A total of 530 water samples were monitored in2018,338 were qualified with the qualified rate of 73.2%. The qualified rate of water samples with surface water and groundwater as water source was 70.8% and 88.7% respectively,and the difference was statistically significant(χ~2=10.100,P<0.05). Among the indicators,the qualified rate of free residual chlorine,chlorine dioxide,and total coliform was 63.2%,76.8% and 73.2%,respectively. Conclusion In Huangshan City,the qualified rate of rural drinking water with groundwater as the source is significantly better than that of water with surface water as the source. The main factors affecting the qualified rate of drinking water in rural areas are disinfectant indicators and microbial indicators. Strengthening the supervision and management and standardizing the construction of drinking water safety project is an effective way to improve the quality of drinking water in rural areas.
