目的了解金乡县农村集中式供水的水质现状,为改善农村生活饮用水的水质提供科学依据。方法在2009年和2010年的枯水期、丰水期对金乡县41处农村集中式供水单位328份水样进行采样和检测。结果 2009年、2010年水样检测合格率分别为70.12%和79.07%,2010年明显高于2009年;丰水期和枯水期合格率分别为71.95%和83.54%,超标率较高的是氟化物、硫酸盐、总硬度。结论金乡县农村集中式供水水质合格率较低,其原因主要是受到地质环境的影响。
Objective To understand the current situation of water quality of rural centralized water supply in Jinxiang County and provide scientific basis for improving the water quality of rural drinking water. Methods During the dry season of 2009 and 2010, 328 water samples from 41 rural centralized water supply units in Jinxiang County were sampled and tested during the wet season. Results The passing rates of water samples in 2009 and 2010 were 70.12% and 79.07% respectively, which were significantly higher in 2010 than in 2009; the passing rates in the wet season and the dry season were 71.95% and 83.54%, respectively. The highest rates of over-standard were fluoride Sulfate, total hardness. Conclusion The qualified rate of centralized water supply in rural areas of Jinxiang County is low due to the influence of geological environment.
