北碚区农村集中式供水水质监测结果分析

目的:了解北碚区农村饮用水卫生状况,为改善和提高农村饮用水质量提供依据,促进农村改水事业的发展。方法:按照国家标准于2008年-2011年枯水期(4月)、丰水期(7月)进行水样的采集、检验和评价。结果:2008年-2011年共检测水样300件,合格105件,合格率35.0%。其中,水质合格率2011年最高,2008年最低,丰水期高于枯水期,差异均有统计学意义(P≤0.05)。在各项检验指标中,微生物指标、感官指标和消毒指标不合格率高,毒理学指标全部合格。结论:近4年来,我区农村饮水安全工程在水源保护、工程设计与管理上都有了长足进步,但总体合格率偏低。各相关单位应完善农村饮用水的监督管理,注重人员培训,强化饮用水消毒工作,以保障农村生活饮用水安全。

Analysis of water quality monitoring results in centralized water supply in rural area of Beibei district

Objective: In order to understand the health situation of drinking water in rural area of Beibei district,and provide scientific basis of water quality to accelerate development of rural water improvement project.Methods: According to the national standard,water samples were collected,detected and evaluated in low water period(April) and high water period(July) from 2008 to 2011.Results: 300 water samples were detected during 4 years,and 105 were up to the standard.The acceptance rate was 35.0%,while the rate in 2011 was highest and 2008 was lowest.The rate in high water period was greater than that in low water period.There was statistical significance(P≤0.05) between the results from different period.In all test indexs,microbial indexes,sensory indexes and disinfectant indexes were generally below proof,toxicological indexes passed completely.Conclusion: In the past 4 years,the district has made considerable progress in water conservation,engineering design and management.However,the overall acceptance rate of drinking water in rural area is still at low levels.The relevant departments should pay much attention to perfect the surveillance system,strengthen the training of manpower and reinforce disinfection to ensure the safety of drinking water in rural area.
