【摘要】 [目的]进一步了解农村饮水安全状况,为改进水源、更加完善地改建扩建农村供水工程提供科学依据。[方法]2008年,对滨州市所辖6县1区农村生活饮用水供水点水样检测资料进行分析。[结果]检测水样96份,合格率为37.50%。水样合格率,以地面水为源水的为56.25%,以地下水为源水的为18.75%(P<0.01)。检测的96份水样中,臭和味、肉眼可见物、耗氧量、砷、硝酸盐氮均合格;单项指标合格率,浑浊度为80.21%,铁为92.71%,锰为91.67%,氯化物为68.75%,硫酸盐为73.96%,溶解性固体为77.08%,总硬度为76.04%,氨氮为93.75%,氟化物为92.71%,菌落总数为54.17%,大肠菌群为79.17%。浑浊度、铁、锰、氯化物、硫酸盐、溶解性固体、总硬度、氨氮、氟化物、总大肠菌群合格率以地下水为源水的水样均低于以地面水为源水的水样(P<0.01或<0.05)。[结论]滨州市农村生活饮用水水质合格率很低,以地下水为源水的水质卫生问题尤其严重,主要的问题是部分化学指标严重超标,水质受到微生物污染。更多还原

【Abstract】 [Objective]To understand safety status of drinking water in rural area,provide a scientific basis for improving water source,perfect reconstruction and expending of rural water-supply project.[Methods]Examination data of water samples from drinking water supply in rural areas of 6 counties and 1 district of Binzhou city were analyzed in 2008.[Results]Of the 96 water samples tested,the qualified rate was 37.50%.The qualified rate of surface source water and ground source water was 56.25% and 18.75% respectively(P<0.01).Of the 96 water samples tested,smell and taste,something visible to the naked eye,oxygen consumption,arsenic,nitrate nitrogen were all up to standard.The qualified rate of turbidity,iron manganese,chloride,sulfate,dissolved solid,total hardness,ammonia nitrogen,fluoride,total colony,coli group was 80.21%,92.71%,91.67%,68.75%,73.96%,77.08%,76.04%,93.75%,92.71%,54.17% and 79.17% respectively.The qualified rate of the content of the 11 items in water samples mentioned above was lower in ground water source than that in surface water source(P<0.01 or <0.05).[Conclusion]The qualified rate of drinking water was lower in rural areas of Binzhou city,especially the water from ground water source.Chemical indicators were seriously over the standard,the water was contaminated with microbe.更多还原
