摘要
目的:为探讨直饮水与末梢水微生物指标的优劣情况。方法:将直饮水与末梢水配对采样监测。结果:直饮水的合格率(89.6%)不及末梢水的合格率(95.8%)(均按CJ94-2005饮用净水水质标准)。结论:直饮水存在二次污染的危险,原因可能是用户的人工维护不够或直饮水机的性能尚需进一步优化。特建议相关部门引起重视。
Objective: To compare the microbial indexes of directly drinking water with that of table - water. Methods: Control samples separately from directing drinking water and table - water were inspected and compared ( under the CJ94 - 2005 criterion of drinking water quality). Results:The eligibility rate of directly drinking water was 89.6% ,which was inferior to that of table - water(95.8% ). Condusion:There is risk of secondary pollution in directly drinking water. The causes are possibly the deficiency of personal maintenances or the disadvantage of water fountain. We suggest that relavent departments pay attention to this problem.
