摘要
目的了解内蒙边境沿线生活饮用水的卫生状况,针对饮用水的水质开展安全评价研究,为相关部门改善水质提供基础性参考。方法采集内蒙边境沿线生活饮用水样品108份(自备水源水70份、自备供水末梢水21份和市政末梢水17份),依据GB 5749—2006《生活饮用水卫生标准》对水质的感官性状指标、一般化学指标、毒理学指标以及微生物学指标进行卫生学评价。结果 108份检测水样中,合格58份,总合格率为53.7%。其中,总大肠菌群不合格率最高(20.4%),其次是氟化物(19.4%);深井水、浅井水和地表水的不合格率比较,差异无统计学意义;自备供水末梢水的不合格率(28.6%)稍高于市政末梢水(17.7%)。结论内蒙边境沿线生活饮用水合格率偏低,微生物指标超标最严重,部分地区氟化物超标。建议增加饮用水水处理消毒设施和水质检测设备,定期对自备供水单位储存水箱进行去垢消毒和保洁维护,同时加大监测力度,防止水性传染病的发生。
Objective To find out about the sanitary conditions of drinking water along the border line of Inner Mongolia via safety evaluation of drinking water along the border line of Inner Mongolia. Methods 108 samples of drinking water along the border line of Inner Mongolia （70 samples of self-supply source water, 21 ones of self-supply tap water and 17 ones of municipal tap water）were collected. Hygienic evaluation of sensory indexes, normal chemical indexes, toxicological indexes and microbiology indexes of water quality was performed according to hygienic standards for drinking water （ GB 5749--2006）. Results 58 samples were qualified with a total qualified rate of 53.7%. The unqualified rate of the total number of coliforms was the highest （20.4%） , followed by fluoride （19.4%）. As for deep wells, shallow wells and surface water, there was no statistically significant difference. Compared with municipal tap water, the unqualified rate of self-supply water （ 28.6% ） was higher （ 17.7% ）. Conclusion The qualified rate along the border line of Inner Mongolia of drinking water is low. Treatment and disinfection facilities for drinking water, detection devices of water quality are needed. The cleaning and disinfection of storage tanks should be performed periodically in oder to prevent waterborne infectious diseases.
