昆山市20家星级酒店餐厅空气质量监测分析

Analysis on the Monitoring of Air Quality of 20 Star Hotel Restaurants in Kunshan

摘要

摘要:
目的通过对江苏省昆山市20家星级酒店餐厅空气质量的调查分析，了解星级酒店餐厅的空气质量现状。
方法随机选取昆山市使用集中空调通风系统的3~5星级酒店20家。在其餐厅内，依据《公共场所卫生监测技术规范》(GB 17220-1998) 的要求设立监测点，共设立监测点127个，于2010年4月到2011年3月对餐厅内温度、湿度、细粒子等11项指标进行连续监测。
结果共监测到数据1 472个，风速、照度、一氧化碳、二氧化碳和菌落总数5项指标的合格率均较高，分别为97.5%、95.1%、100.0%、97.9%、97.6%。温度、湿度、新风量的合格率较低，分别为69.3%、61.4%、16.0%。
结论昆山市星级餐厅的空气质量总体良好，但餐厅的新风量、温度、湿度合格率较低，应该发挥集中空调在餐厅小气候调节方面的作用。

Abstract:
Objective To explore the sanitary quality of indoor air in star hotel restaurants in Kunshan city.
Methods According to the rule of health monitoring for public places, continuously monitoring the temperature, relative humidity, PM2.5 and other indicators were conducted in 127 stations of 20 three to five star hotel restaurants which use central air conditioning as ventilation system in Kunshan city from Apr. 2010 to Mar. 2011.
Results There were 1472 environmental surveillance data, the passing rates of wind velocity, luminance, carbon monoxide, carbon dioxide and aerobic bacterial count were 97.5%, 95.1%, 100.0%, 97.9%, 97.6% respectively, and which was relatively high. The passing rates of temperature, relative humidity and fresh air volume were 69.3%, 61.4% and 16.0% respectively, which were relatively low.
Conclusions The air quality in star hotel restaurants was good in general in Kunshan city, however the passing rates of temperature, relative humidity and fresh air volume were low; the role of regulating the microclimate conducted by central air conditioning should be strengthened.
