新装修房屋室内空气污染物的监测及防治技术

Monitoring and Control Technology of Indoor Air Pollutants in Newly Renovated Houses

本文主要探究了新装修房屋室内空气污染物的监测方法以及预防、治理措施。以某新装修房屋作为研究对象,在室内设置5个采样点,采集空气样品并检测总挥发性有机物、甲醛、氨的浓度。首次检测结果表明,新装修房屋内各类空气污染物的浓度均超出标准规定的限值。一个月后再次检测,除总挥发性有机物和氨的浓度仍然超标外,其他各类空气污染物浓度均符合标准规定。对于新装修房屋室内空气污染物,应当以预防为主、治理为辅;采取定期开窗通风和使用纳米光触媒等措施,能够有效降低室内空气污染物的浓度。

This paper mainly explores the monitoring methods and prevention and treatment measures of indoor air pollutants in newly renovated houses.In this paper,five sampling points were set up in a newly renovated house to collect air samples and detect the concentration of total volatile organic compounds,formaldehyde and ammonia.The first test results showed that the concentration of various air pollutants in the newly renovated houses exceeded the limits specified in the standard.A month later,the concentration of total volatile organic compounds and ammonia still exceeded the standard,and the concentration of other types of air pollutants met the standard.For indoor air pollutants in newly renovated houses,prevention should be the main,and treatment should be supplemented;The concentration of indoor air pollutants can be effectively reduced by regularly opening Windows for ventilation and using nano-photocatalysts.
