目的了解北京市房山区农村自备水源生活饮用水水质状况,为有关部门采取措施提供科学依据。方法采取普查方式,采集19个乡镇168件自备水源水样,按照国家标准方法进行微生物指标的检测。结果房山区农村自备水源生活饮用水水质合格率仅为85.9%,其中平原地区合格率为89.4%,山区合格率为72.4%,平原地区合格率高于山区,差异有统计学意义(P<0.05)。平原地区菌落总数、大肠菌群、耐热大肠菌群合格率均高于山区,差异有统计学意义(P<0.05)。结论北京市房山区农村自备水源水质状况堪忧,应尽快采取措施,加强水源管理,改善水质状况。生活饮用水水质状况受人们的生活环境、居住条件、卫生意识的影响,改善生活饮用水水质状况必须加强水源管理。
Objective To understand the water quality of drinking water sourced from rural areas in Fangshan District of Beijing and provide scientific evidence for the relevant departments to take measures. Methods Census method was adopted to collect 168 water samples from 19 villages and towns, and the microbial index was tested according to the national standard method. Results The water quality of drinking water sourced from rural areas in Fangshan District was only 85.9%. The pass rate in plain area was 89.4% and that in mountain area was 72.4%. The pass rate in plain area was higher than that in mountainous area (P < 0.05). The total number of colony, coliform and heat-resistant coliform bacteria in the plain area were higher than that in mountainous area, the difference was statistically significant (P <0.05). Conclusion The water quality of self-provided water sources in Fangshan District, Beijing is worrying. Steps should be taken to speed up water source management and improve water quality.
