本文利用空气离子浓度和耗氧量为室内空气质量监测指标,对几家饭店及舞厅进行了监测,结果显示,三个舞厅开场前的CO、CO_2浓度低,耗氧量也低,开场后一小时,CO、CO_2浓度增高,耗氧量也增高。空气负离子浓度与耗氧量呈负相关,r=-0.354(P<0.01),即空气耗氧量越高,负离子浓度越低。空调房间负离子浓度降低,使用现代装璜材料的场所耗氧量高因其含有机物多。我们建议,以上两项可用作空气质量的评价指标。
In this paper, air ion concentration and oxygen consumption for indoor air quality monitoring indicators, several hotels and dance halls were monitored, the results show that before the opening of the three ballroom CO, CO 2 concentration is low, the oxygen consumption is also low, after the opening of a Hour, CO, CO 2 concentration increased, oxygen consumption also increased. Air anion concentration and oxygen consumption was negatively correlated, r = -0.354 (P <0.01), that is, the higher the air oxygen consumption, the lower the concentration of negative ions. Air-conditioned room to reduce the concentration of negative ions, the use of modern materials, decorative places high oxygen consumption because of its organic matter and more. We recommend that the above two can be used as air quality evaluation indicators.
