目的调查成都双流国际机场航空器二次供水卫生状况,为确保机组和旅客用水卫生安全提供依据。方法对双流国际机场2007—2013年航空器二次供水的水样进行细菌总数、总大肠菌群、游离性余氯、色度、臭和味、p H值、浑浊度、肉眼可见物8项指标进行检测和评价。结果加水站水质合格率最高,加水站出水水质长期保持合格状态;加水车水质合格率能够保持较高的水平;但航空器水抽样结果合格率偏低;加水车水质合格率与加水站水质有明显联系,而航空器水水质与其他两项水质无明显关系;经检测双流国际机场航空器二次供水主要问题是游离氯和菌落总数不合格。结论双流国际机场加水站能够为双流国际机场提供符合卫生要求的航空器二次供水,加水车能够为航空器中转提供安全的机用饮用水,但是航空器水依然存在安全隐患,应加强水中游离氯水平和微生物污染控制。
Objective To investigate the sanitary status of secondary water supply of Chengdu Shuangliu International Airport aircraft and provide the basis for ensuring the hygiene and safety of the crew and passengers. Methods The total number of bacteria, total coliform bacteria, free residual chlorine, color, odor and taste, p H value, turbidity, and macroscopic indexes of eight secondary water samples of Shuangliu International Airport from 2007 to 2013 were measured. For testing and evaluation. Results The qualified rate of water quality in water station was the highest, and the water quality of water station was maintained in good condition for a long time. The qualified rate of water quality in water tanker could be maintained at a high level. However, the qualified rate of water sampling in aircraft was low. , While the quality of aircraft water has no obvious relationship with the other two water quality. The main problem of secondary water supply of aircraft tested at Shuangliu International Airport is that the total number of free chlorine and colony is unqualified. Conclusions Shuangliu International Airport refueling station can provide Shuangliu International Airport with secondary water supply meeting the hygiene requirements. Water tankers can provide safe drinking water for aircraft transit. However, there are still potential safety hazards in aircraft water, and the level of free chlorine in water should be strengthened. Microbial contamination control.
