目的掌握新疆南疆铁路管辖人群聚集较集中的4个地区水源水质卫生状况,确保铁路职工家属的饮水卫生安全。方法按照《生活饮用水标准检验方法水样的采集与保存》(GB/T5750-2006)的规定采样,并依照《生活饮用水标准检验方法》(GB/T5750-2006)卫生学检测。结果感官性状指标检测72项,合格率100.00%;化学指标检测234项,合格率88.03%;毒理学指标检测198项,合格率100.00%;微生物指标检测72项,合格率100.00%;消毒剂指标检测36项,合格率0。结论水源水均为地下水,氯化物、硫酸盐的含量较高,水质硬度较高,可能与所处的地理位置有关,也可能是由于地下水位改变造成个别指标超标;应该加强水质净化消毒、水源卫生管理、水质监测和卫生监督工作。
Objective To understand the hygienic condition of water quality in the four areas where the jurisdiction of railway population of Xinjiang southern Xinjiang is concentrated and to ensure the hygiene and safety of the families of railway workers. Methods Sampling was conducted according to the requirements of “Collection and Preservation of Water Samples for Drinking Water Standard Test Method” (GB / T5750-2006), and the hygiene test was conducted according to “Standard Test Method for Domestic Drinking Water” (GB / T5750-2006). Results Sensory traits index test 72, the pass rate of 100.00%; 234 chemical indicators, the passing rate of 88.03%; toxicological indicators of 198, the pass rate of 100.00%; 72 microbial indicators, pass rate of 100.00%; disinfectant indicators 36 tests, the pass rate of 0. Conclusions The water of source water is groundwater, with high content of chlorides and sulfates, high hardness of water, which may be related to the geographical location, or may be due to the exceeding of some indexes due to the change of groundwater level. It is necessary to strengthen the purification and disinfection of water quality, Health management, water quality monitoring and health supervision.
