摘要
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 of rural drinking water quality in Tangshan City, and provide scientific basis for the surveillance management of rural drinking water. Methods Rural drinking water qualities of 330 monitoring points in 5 counties of Tangshan city were monitored, detected and analyzed according to the Drinking water standard testing method GB/T 5750 -2006, and Hygienic standard for drinking water GB 5749 - 2006. Results A total of 660 water samples were monitored and there were 321 qualified samples, accounting for 48.6%. The detecting indicators that qualified rate of 100% were： chroma, stink and taste, Oxygen consumption, arsenic and chloride; The indicators with a lower qualified rate were the total coliform group （71.54%）, fluoride （84%）, nitrate （94.30%）, turbidity （94.62%）, and the total bacterial count （95.69%） . Conclusions There are still many problems of rural drinking water in Tangshan city, mainly focused on microbial contamination, improper water source management and uneffective improper disinfection not effectively are major causes of microbial exceed the standard in rural drinking water, should strengthen the management and disinfection of drinking water source.
