摘要
本文通过调查阜新市农村小型集中供水和城市生活饮用水的微生物和理化指标,检测当地生活饮用水各项数据,以期为居民生活饮用水的安全保障工作提供科学依据。本研究依托国家生活饮用水监测战线任务,在阜新市的2个县和5个区设立监测点。于2017—2019年,每年枯水期(4—6月)、丰水期(8—9月)各检测1次。2017—2019年检测监测点水样共计373份,检测方法和水质评价按照国家标准(GB/T5750-2006、GB/T5749-2006)进行。结果显示,373份水样中,271份合格,总体合格率为72.65%。2017—2019年合格率分别为60.14%、89.81%和72.13%。城市生活饮用水、农村小型集中供水合格率分别为85.96%、29.55%;枯水期、丰水期合格率分别为82.61%、62.96%。由此可见,阜新市城市生活饮用水总体状况良好,农村小型集中供水合格率偏低,且主要不合格项目在于微生物指标,建议加强对农村小型集中式供水的监测力度,改善和加强农村供水和消毒设备,保障用水卫生安全。
To investigate the microbiological and chemical indicators of small-scale centralized water supply and urban domestic drinking water in Fuxin City.This study provided a scientific basis for relevant administrative departments to ensure the safety of residents'drinking water.This study set up monitoring points in two counties and five districts of Fuxin based on the national drinking water monitoring subject.This monitoring operated once each year during the low water period(April to June)and the high water period(August to September)from 2017 to 2019.A total of 373 water samples were monitored from 2017 to 2019,and the testing methods and water quality evaluation were conducted in accordance with national standards(GB/T5750-2006,GB/T5749-2006).373 of the water samples,271 were qualified,with an overall pass rate of 72.65%.The pass rates from 2017 to 2019 are 60.14%,89.81%and 72.13%respectively.The pass rates for urban domestic drinking water and rural small-scale centralized water supply are 85.96%and 29.55%,respectively;the pass rates for dry and high water periods are 82.61%and 62.96%.The overall status of urban drinking water in Fuxin is satisfied?,the qualification rate of small-scale centralized water supply in rural areas is low,and the main unqualified items are reflected in the microbiological indicators.This study suggests strengthening the monitoring of rural centralized water supply,improving and strengthening rural water supply and disinfection equipment to ensure the sanitation and safety of water use.
