乌鲁木齐铁路局管辖地区生活饮用水水质卫生调查

为了全面了解乌鲁木齐铁路局管辖地区生活饮用水卫生状况，对乌铁局所管辖范围的南疆、北疆、东疆铁路沿线及乌鲁木齐共１２７个水源点分别在丰水期和枯水期进行了２７个项目的全面系统的水质检验，采集样品共２５４份，共测有效数据６７７７个，结果表明：大多粉分析指标符合国家生活饮用水卫生标准，超标项目分别为氯化物超标率１１．２％，硫酸盐超标率２３．１％，总硬度超标率为１６．３％，溶解性总固体超标率为２７．１％，总

Hygienic Survey of Dringking Water Quality in Area Controlled Over by WuLuMuQi Railway Department

To understand the hygienic situation of drinking water quality in the areas controlled over by WuLuMuQi Railway Department,we made a 27\|item water quality inspection along Nanjiang,Beijiang,Dongjiang and WuLuMuQi Railway in 1994,which consisted of 127 water sources and was carried out in high and low water season respectively.254 Samples were examined and 6 777 indexes were available.It showed that most items were accorded to the National Hygienic Standard of drinking water.Items over the standard were:chloride(11 2%),sulphate(23.1%),total hardness(16 3%),resoluble total solid(17.5%),fluoride(2.0%),total coliform group(27.1%),ammonia\|nitrogen(5.6%),nitrite(3.2%),turbidity scale(5.2%),degree of color (0.8%) and oxygen demand (0.4%).Except for total coliform group and few items,the maximum values over the standard were not too high,the range of them was between (0.1~3.2).These excesses were caused by bad natural quality of ground water and pollution of surface water.We also proposed that water\|borne communicable diseases had decreased gradually these years and analyzed the relationship between drinking water quality and water\|borne communicable diseases,and pointed out the importance and requirement of hygienic protection of water supply sources.
