目的:了解南丹县农村饮用水水质状况,对2006年-2011年南丹县农村饮用水监测结果进行分析。方法:每年采集枯水期和丰水期水样按《生活饮用水标准检验方法》(GB/T5750-2006)进行检测分析。结果:599份水样不合格项目主要为浑浊度、肉眼可见物、砷、氨氮、菌落总数、总大肠菌群、耐热大肠菌群,水样总合格率为23.04%,年度合格率有显著性差异(χ2=26.19、P<0.01),枯水期与丰水期合格率有显著性差异(χ2=13.11、P<0.01),出厂水与末梢水合格率无显著性差异(χ2=1.39、P>0.05)。结论:南丹县农村饮用水水质卫生状况较差,合格率低,因此应加强农村饮用水水质监测,以保障农村饮水安全。
Objective: To understand the water quality of rural drinking water in Nandan County and analyze the monitoring results of rural drinking water in Nandan County from 2006 to 2011. Methods: The water samples collected during the dry season and wet season were collected and analyzed according to “Standard Test Method for Domestic Drinking Water” (GB / T5750-2006). Results: The 599 water samples were mainly turbidity, macroscopic, arsenic, ammonia nitrogen, colony, total coliforms, heat-resistant coliform bacteria, the total qualified rate of water samples was 23.04%, the annual pass rate was significant (Χ2 = 26.19, P <0.01). There was a significant difference in pass rates between dry season and wet season (χ2 = 13.11, P <0.01) > 0.05). Conclusion: The quality of drinking water in rural areas in Nandan County is poor and the pass rate is low. Therefore, the monitoring of drinking water quality in rural areas should be strengthened to ensure the safety of rural drinking water.
