摘要
为了掌握哈尔滨市建筑装饰装修造成的室内空气污染状况,对哈市7区百余户室内空气甲醛、氨和苯系物进行了检测分析,污染物超标率甲醛85 2%,氨53 1%,苯50 7%.针对哈尔滨地域特点进行了冬季通风、光催化和臭氧氧化降低室内空气甲醛和氨污染效果的现场实验,结果表明:延长通风时间室内甲醛质量浓度降低程度比氨大.光催化空气净化器在开启的前30min效果显著,氨浓度净化效果有起伏,效果不明显.臭氧氧化对降低室内空气甲醛和氨质量浓度没有明显效果.
A survey was conducted to investigate the indoor air pollution after room decoration within 7 districts in Harbin and such pollutants as formaldehyde, ammonia and benzene series were sampled and analyzed for over 100 houses. Of all the samples collected, 85.2% of formaldehyde, 53.1% of ammonia and 50.7% of benzene exceeded the standard criterion. Pertinent to the regional status in Harbin, a study was carried out to investigate into the effect of ventilation, photocatalysis and ozonization on the reduction of indoor formaldehyde and ammonia. Experimental results showed that extended ventilation had better reduction of formaldehyde than ammonia, obvious pollutants reduction might be achieved within 30 min of photocatalysis although fluctuated for ammonia, and no obvious reduction of formaldehyde and ammonia were observed in the case of ozonization.
