目的掌握淄博市张店区农村饮用水的水质卫生状况,分析影响水质安全的主要因素,为农村饮用水卫生管理提供决策依据。方法依托国家及省市级农村饮水安全工程、监测点水质监测及水质基线调查,选取36个村,于2008—2016年于丰水期和枯水期各采集末梢水1份。结果 2008—2016年共采集水样648份,合格水样320份,总合格率为49.38%;合格率较低的项目为菌落总数(61.62%)、总大肠菌群(84.72%)、耐热大肠菌群(87.22%);城市集中式供水的合格率远高于农村自备井,差异均有统计学意义(均P<0.05)。结论淄博市张店区农村生活饮用水的水质安全问题仍有待改善,影响水质合格的主要因素是细菌学指标。
Objective To understand the sanitary status of rural drinking water in Zhangdian District, Zibo City, analyze the main factors that affect water quality and safety, and provide decision-making basis for rural drinking water health management. Methods Based on the national drinking water safety project at rural and urban areas, water quality monitoring of monitoring points and baseline survey of water quality, 36 villages were selected and 1 peripheral water was collected in both wet and dry periods during 2008-2016. Results A total of 648 water samples and 320 qualified water samples were collected during 2008-2016. The total pass rate was 49.38%. The lower pass rates were total number of colonies (61.62%), total coliforms (84.72%), Coliform (87.22%). The qualified rate of urban centralized water supply was much higher than that of rural self-prepared wells (all P <0.05). Conclusion The water quality and safety of rural drinking water in Zhangdian District of Zibo City needs to be improved. The main factor that affects water quality is bacteriological index.
