目的 监测取暖方式对居室空气卫生质量的影响。方法 以集中供暖的一楼居室为参考,对朝向和面积相同的单居式土暖气、一炉多房用小暖气及煤球炉分散取暖的平房居室,用干湿球温度计测定室温,气相色谱法测定CO,盐酸萘乙二胺比色法测定NO_x,盐酸副玫瑰苯胺比色法测定SO_2,WFC改良培养基和JWL-Ⅱ型空气微生物监测仪检测空气中细菌总数。结果 在室温15～18℃下,不同取暖方式居室内CO浓度为2.62～7.52mg/m~3,NO_x为0.102～0.186 mg/m~3,SO_2为0.522～0.916mg/m~3,细菌总数为980～2960cfu/m~3。不同取暖方式之间居室空气卫生质量存在差别。结论 分散取暖方式对居室空气卫生质量影响较大。
Objective To monitor the influence of heating methods on the hygiene quality of living room air. Methods Based on the first-floor room with central heating, the bungalow room was heated and distributed in the same direction with the same area of single-family soil heating, one-room multi-room heating and briquettes furnace. The room temperature and gas chromatography Determination of CO, naphthylethylenediamine hydrochloride colorimetric determination of NO_x, pararosaniline hydrochloric acid colorimetric determination of SO_2, WFC modified media and JWL-Ⅱ type of air microbial monitoring instrument to detect the total number of bacteria in the air. Results The indoor CO concentration was 2.62 ~ 7.52 mg / m ~ 3, the NO_x was 0.102 ~ 0.186 mg / m ~ 3 and the SO_2 was 0.522 ~ 0.916 mg / m ~ 3 at room temperature 15 ~ 18 ℃ .The total number of bacteria For 980 ~ 2960cfu / m ~ 3. There is a difference in hygiene quality of room air between different heating methods. Conclusion The decentralized heating method has a great influence on the hygienic quality of indoor air.
