兰州市绿色建筑室内空气中苯和TVOC污染研究

Study on Benzene and TVOC Pollution in Green Building Indoor Air in Lanzhou City

为了解兰州市绿色建筑室内空气中苯和TVOC污染程度,通过对兰州市碧桂园二期一星级绿色居住建筑长期检测,确定绿色建筑室内空气苯和TVOC浓度水平及影响因素。试验结果表明:同一房间不同功能区室内空气苯浓度表现为卧室>客厅>厨房,TVOC浓度表现为卧室>厨房>客厅;随着高度的增加,室内空气苯和TVOC浓度逐渐降低;新风系统的运行可有效降低室内空气苯和TVOC污染;室内装饰装修会显著增加室内空气苯和TVOC污染;兰州市绿色建筑室内空气苯和TVOC污染相对较轻。

In order to understand the degree of benzene and TVOC pollution in the indoor air of green buildings in Lanzhou,the long-term detection of 1-star green residential buildings in the second phase of country garden in Lanzhou city was conducted to determine the concentration level of benzene and TVOC in the indoor air of green buildings and the influencing factors.The results showed that benzene concentration in different functional areas of the sa me room was>living room>kitchen,and TVOC concentration was>kitchen>living room;with the increase of the height,the concentration of benzene and TVOC in indoor air decreased gradually,the fresh air system can effectively reduce indoor air benzene and TVOC pollution;indoor decoration will significantly increase indoor air benzene and TVOC pollution;the indoor air pollution of green buildings in Lanzhou is relatively light in benzene and TVOC.
