农村沼气建设对室内空气质量影响探析

Analysis of Impacts of Developing Rural Biogas on Indoor Air Quality

结合农村地区室内空气质量污染现状和影响因素,对河南省孟州市赵和乡苏庄村5户沼气用户和3户非沼气用户室内空气中污染物CO、SO2、NH3、PM10等含量进行了动态监测,对比分析了沼气建设对农户室内空气质量的影响。结果表明,沼气建设项目实施后,沼气用户室内空气中CO、SO2、NH3、PM104项污染指标浓度明显下降,较非沼气用户分别减少了93.5%、62.9%、48.1%、25.9%,农户室内空气质量明显改善。

To investigate the rural indoor air quality pollution status and some influencing factors, 5 biogas farmers and 3 non-biogas ones were chosen to analyze the concentrations of CO, SOz, NH3 ,PM10 in the indoor air in Suzhuang village, Zhaohe town, Mengzhou city, Henan province. The results showed that the concentrations of CO, SO2 ,NH3 ,PM10 in the indoor air of household- er building the rural biogas were remarkedly lower than those without the rural biogas,which de- creased 93.5%, 62.9 %, 48.1%, 25.9 %, respectively. In conclusion, developing the rural biogas could improve the indoor air quality.
