目的为了解济南铁路地区生活饮用水卫生质量,保障铁路运输和职工生活饮用水的卫生和安全。方法对济南铁路地区供水单位的供水水质进行菌落总数和总大肠菌群检测分析。结果共采集水样808份,总合格638份,总合格率为78.96%。二次供水合格率最高,为84.43%;其次为集中式供水,合格率为82.19%;分散式供水合格率最低,为68.64%。不同供水方式影响水质卫生安全,差异有统计学意义(P<0.01)。不同年份生活饮用水菌落总数和总大肠菌群检测合格率不同(P<0.01),不同季度检测合格率不同(P<0.05),市区供水合格率高于农村。结论虽然济南铁路地区生活饮用水的卫生质量逐年提高,但是仍受供水方式、季度及地区等因素影响,因此应加强对水厂制供水人员及各单位供水管理人员的卫生知识、卫生法律法规的学习培训,提高饮用水卫生保护意识。
Objective To understand the hygienic quality of drinking water in Jinan railway area and to ensure the hygiene and safety of railway transportation and drinking water for staff and workers. Methods The total number of colony and total coliforms in water supply units of Jinan Railway Region were detected and analyzed. Results A total of 808 water samples were collected, totaling 638 samples, with a total pass rate of 78.96%. Secondary water supply the highest pass rate of 84.43%; followed by centralized water supply, with a pass rate of 82.19%; decentralized water supply with the lowest pass rate of 68.64%. Different ways of water supply affect the hygiene and safety of water quality, the difference is statistically significant (P <0.01). The total number of drinking water colony in different years and the total coliform test pass rate were different (P <0.01). The passing rates in different quarters were different (P <0.05), and the passing rate of urban water supply was higher than that in rural areas. Conclusions Although the sanitary quality of domestic drinking water in Jinan railway area has been increasing year by year, it is still affected by factors such as water supply method, quarterly period and area. Therefore, it is necessary to strengthen the hygiene knowledge of water supply staff and water supply managers of all units, health laws and regulations Learning and training to raise awareness of drinking water health protection.
