目的 了解哈尔滨市2013—2015年农村生活饮用水中微生物指标状况,为保障农村地区生活饮用水卫生安全提供科学依据。方法 按照哈尔滨市饮用水卫生监测工作方案要求,对农村生活饮用水开展监测,根据《生活饮用水标准检验方法》(GB/T 5750-2006)进行菌落总数、总大肠菌群和耐热大肠菌群3项微生物指标检验,根据《生活饮用水卫生标准》(GB 5749-2006)对水质进行评价。结果 2013—2017年共检测4 010份水样,微生物总体合格率为95.26%(3 820/4 010),各年度合格率之间存在差异(χ2=120.34,P<0.01)。2013—2017年各年度饮水中菌落总数、总大肠菌群和耐热大肠菌群合格率存在显著性差异(χ2分别为107.15、70.12和84.62,P<0.01);5年间枯水期和丰水期水样微生物合格率分别为95.31%(1 911/2 005)和95.21%(1 909/2 005),各年度枯水期和丰水期饮水中微生物合格率之间存在显著性差异(枯水期和丰水期χ2分别为66.02和54.62,P<0.01);5年间出厂水和末梢水微生物合格率分别为95.22%(1 794/1 884)和95.30%(2 026/2 126),各年度出厂水和末梢水中微生物合格率之间存在显著性差异(出厂水和末梢水χ2分别为58.60和61.79,P<0.01);各年度未予处理饮水微生物合格率之间存在显著性差异(χ2=128.64,P<0.01)。结论 哈尔滨市农村生活饮用水微生物指标监测结果相对较好。需要进一步规范生活垃圾污水排放及粪便有序排放,加强饮用水消毒等措施以促进农村居民生活饮水质量的提高。

Objective To investigate the microbial indices in rural drinking water in Harbin, China from 2013 to 2017, and to provide a scientific basis for maintaining drinking water safety in rural areas. Methods The rural drinking water was monitored according to the requirements of the drinking water safety monitoring program in Harbin. The total number of bacterial colonies, total coliform, and heat-resistant coliform bacteria were examined according to the Standard Examination Method for Drinking Water (GB/T 5750-2006), while the water quality was evaluated according to the Standards for Drinking Water Quality (GB 5749-2006). Results A total of 4 010 water samples were tested from 2013 to 2017. The overall microbial qualified rate was 95.26% (3 820/4 010). There was a significant difference in the overall qualified rate among different years (χ2=120.34, P<0.01). There were significant differences in the qualified rates for the total number of bacterial colonies, total coliform, and heat-resistant coliform bacteria among different years in 2013-2017 (χ2=107.15, P<0.01; χ2=70.12, P<0.01; χ2=84.62, P<0.01). During the five years, the overall microbial qualified rates in dry and wet seasons were 95.31% (1 911/2 005) and 95.21% (1 909/2 005), respectively. There were significant differences in the overall microbial qualified rates in dry and wet seasons among different years (dry season:χ2=66.02, P<0.01; wet season:χ2=54.62, P<0.01). During the five years, the overall microbial passable rates for finished water and terminal piped water were 95.22% (1 794/1 884) and 95.30% (2 026/2 126), respectively. There were significant differences in the overall microbial passable rates for finished water and terminal piped water among different years (finished water:χ2=58.60, P<0.01; terminal piped water:χ2=61.79, P<0.01). There was a significant difference in the overall microbial passable rate for untreated drinking water among different years (χ2=128.64, P<0.01). Conclusion The rural drinking water in Harbin achieves a satisfactory result for microbial indices monitoring. In order to improve the quality of rural drinking water, domestic sewage and fecal discharges should be further standardized and disinfection of drinking water should be enhanced.
