摘要
依据中华人民共和国国家标准《生活饮用水卫生标准》GB5749—2006和《生活饮用水标准检验方法》GB/T5750—2006对我校的几种饮用水(特别是教师村)的水质指标进行检测。检测结果表明:1)学校生产的桶装水各项指标均符合要求;2)校园自来水公司正常送水水质符合要求,但教师村水管爆裂修缮后12小时内供水水质色度、浑浊度、铝、铁、硫酸盐及水的总硬度不达标;3)安装净水处理装置对水质理化及毒性指标未见异常,但大肠菌群及菌落总数计数两项微生物指标均显著异常,表明净水处理装置并不一定完全有效,可能造成二次细菌污染。
The methods according to＂Drinking Water Standards＂,GB5749—2006,and＂living standards for drinking water testing methods＂,GB/T5750—2006 to detect our campus several kinds of drinking water quality （especially for our university faculty and staff residential district）.The results indicated that：1） water quality from our university barreled water factory can meet the standard requirements;2） the water quality of the campus from water supply company also meet the standard requirements,but the water quality of our university faculty and staff residential district in 12 hours after being repaired after pipe bursted is of being worried such as color,turbidity,aluminum,iron, sulfate and total hardness of water;3） the water quality of physics,chemistry and the toxic target has not been seen exceptionally after installing the water purifying equipment,but the total number of coliform bacteria and the total colony count of bacteria are significantly abnormal.Therefore,the water purifying devices are not completely effective. It may cause secondary bacterial contamination.
