目的为了解建平县农村生活饮用水水质卫生状况,为农村安全饮水工程和政府部门制定政策提供基础依据。方法根据GB/T5750-2006标准要求进行采样、检测;按GB/T5749-2006标准进行评价。结果 2009-2012年共检测样品776份,合格648份,合格率83.5%,各年度合格率分别为77.9%、81.2%、81.1%和91.8%,差异有统计学意义(χ2=16.29,P<0.01);所检测的26项指标中,微生物指标合格率最低;枯水期与丰水期水质合格率无统计学意义(χ2=0.05,P>0.05)。人、畜粪便及有机物污染为本地区水质卫生的主要问题。结论选择水量充足、水质良好、易于防护和取水方便的水源作为取水点;加强水质净化和消毒的管理,确保水质安全卫生。
Objective To understand the sanitary conditions of drinking water quality in rural areas in Jianping County and provide the basis for the formulation of policies for rural safe drinking water projects and government departments. Methods According to GB / T5750-2006 standard requirements for sampling, testing; according to GB / T5749-2006 standard for evaluation. Results A total of 776 samples were tested in 2009-2012, with a pass rate of 648 and a pass rate of 83.5%. The pass rates in each year were 77.9%, 81.2%, 81.1% and 91.8%, respectively, with significant differences (χ2 = 16.29, P < 0.01). Among the 26 indicators tested, the passing rate of microbial indicators was the lowest. There was no significant difference in water quality between dry season and wet season (χ2 = 0.05, P> 0.05). Man, livestock excrement and organic pollution as the main problems of water quality in this area. Conclusions The water source with sufficient water quantity, good water quality, easy protection and water abstraction is selected as the water abstraction point. The management of water quality purification and disinfection should be strengthened to ensure the water quality safety and hygiene.
