摘要
随着国民经济的增长、室内装修的快速发展,其带来的负面影响也不得不被人们所重视。通风是目前解决室内空气污染的首要选择,但是辽宁地区的居民在过渡季时开窗受到室外PM2.5污染影响。为了探究辽宁地区自然通风的过渡季室内甲醛污染现状,采用酚试剂分光光度法对该地区机械通风与自然通风共29户住户进行密闭与通风两种工况的实地入户测试。过渡季密闭工况下的平均甲醛浓度为0.090 mg/m^3,通风工况下甲醛浓度为0.044mg/m^3。过渡季节,在室外条件适宜的情况下,居民应多开窗户达到去除室内甲醛的效果。
With the growth of the national economy,the negative impact of the interior decoration has to be taken seriously.Ventilation is currently the primary choice for addressing indoor air pollution,but residents in Liaoning have been affected by outdoor PM2.5 pollution during the transition season.In order to explore the status of indoor formaldehyde pollution in the transitional season of natural ventilation in Liaoning,phenol reagent spectrophotometry was used to test the 29 local households by both mechanical ventilation and natural ventilation in the closed and ventilated conditions.The results show that average formaldehyde concentration in the closed condition is 0.090 mg/m3,while the formaldehyde concentration in the ventilation condition is 0.044 mg/m3.Therefore,when outdoor conditions are appropriate,residents should open windows during the transitional season to achieve the effect of removing formaldehyde indoors.
