目的了解唐山市农村生活饮用水水质现状,为农村生活饮用水监督管理提供科学依据。方法对唐山市5个县区330个监测点的农村生活饮用水水质进行监测,按照《生活饮用水标准检验方法》GB/T5750-2006、《生活饮用水卫生标准》GB5749-2006进行检测、评价和分析。结果共监测水样660份,合格321份,样品合格率为48.6%。合格率达100.00%的指标为:色度、臭和味、耗氧量、砷、氯化物;合格率较低的指标是:总大肠菌群(71.54%)、氟化物(84.00%)、硝酸盐(94.30%)、浑浊度(94.62%)、菌落总数(95.69%)。结论唐山市农村饮用水卫生仍然存在较多问题,以微生物污染为重,水源管理不当及消毒工作未有效开展是农村饮用水微生物超标的主要原因,应加强饮用水水源管理及消毒工作。
Objective To understand the status quo of drinking water quality in rural areas of Tangshan City and to provide a scientific basis for the supervision and management of rural drinking water. Methods The water quality of rural drinking water at 330 monitoring points in 5 counties of Tangshan City was monitored. According to “Standard Test Method for Domestic Drinking Water” GB / T5750-2006, “Sanitation Standard of Domestic Drinking Water” GB5749-2006, it was tested and evaluated And analysis. Results A total of 660 water samples were collected, of which 321 were qualified. The pass rate of samples was 48.6%. The pass rate of 100.00% was: color, odor and taste, oxygen consumption, arsenic and chloride. The indicators with low passing rate were total coliforms (71.54%), fluoride Salt (94.30%), turbidity (94.62%), total number of colonies (95.69%). Conclusion There are still many problems in drinking water hygiene in rural areas in Tangshan City. The main reason is the microbial pollution, improper management of water sources and the ineffective disinfection of drinking water in rural areas. Therefore, the management and disinfection of drinking water sources should be strengthened.
