新建本科院校室内空气中甲醛含量的现状及影响因素与治理措施

The Status of Formaldehyde Content in the Indoor of Newly-Built Universities and Its Influencing Factors and Management Measures

为了解新建大学室内空气中甲醛的含量状况,分析其影响因素,并提出科学合理的治理措施,对大学普通教室、新改建教室、校办公室、校会议室、纪念馆、图书馆、实验室等典型样地进行了室内空气中甲醛指标的测定。经研究发现,校会议室空气中甲醛含量最大,新改建教室甲醛含量次之,仍高于国家室内空气甲醛含量标准。甲醛含量偏高的主要来源是新家具与新装修材料中甲醛的释放,应该采取经常通风的措施,放置固体活性炭和可吸收甲醛的植物等措施,降低室内甲醛浓度,保障师生的健康。

In order to understand the status of the newly-built university of formaldehyde content in indoor air,analyze its influencing factors,and put forward the scientific and reasonable control measures,the formaldehyde content was measured in the indoors air of ordinary university classrooms,newly-rebuilt classroom,the school offices,conference rooms,libraries,museum and laboratories.The results showed that the formaldehyde content was the highest in the air of the conference rooms.And the formaldehyde content was the second highest in the newly-rebuilt classroom.Both of the formaldehyde contents were higher than the national indoor air formaldehyde content standard.The main source of formaldehyde content was released by new furniture and decoration materials.To reduce the formaldehyde content,it should be often ventilation,put activated carbon and formaldehyde-absorbed ornamental plants to protect health of teachers and students.
