兰西拉光缆工程沿线水源卫生调查

Investigation of Water Sources Along the LanXiLa Cable Line

目的 了解青藏线水源水质卫生状况，为施工部队水源选择、洁治消毒提供参考依据。方法 硬度使用ＥＤＴＡ－２Ｎａ进行滴定，其余指标使用８８型检水检毒箱测定。结果施工沿线基本无现成可利用的水源，所调查２２个水源中９个存在生物污染，３个水源氯化物或硫酸盐严重超标；５个水源总铁严重超标。结论 摸清了放工沿线水源水质卫生状况，为部队施工和以后执行任 务时选择水源、进行水质改善提供了科学依据。

We did this investigation to get the information of the quality of the water soures along the LanXiLa line. So the cable laying troops couid make use of it to choose the right water source for drink and do right disinfection and treatment. We tested the water hardness by us- ing EDTA-2Na, we got the other index result by using 88-type Water Quality And Toxin Quick Test BOX. Through the investigation we find there is almost no water ready for use without treat,nine out of the 22 water sources are biologically polluted,three are much high- er than the normal standard in choride and solphate,five are much higher in ferrite. So we should choose the water source and treat the water specially before drink.
