北方冬季农村供暖对PM2.5的影响及解决方案研究

为研究北方冬季农村供暖对PM2.5的影响,我们在北方的部分乡镇农村进行了为期一年半的调查走访,结果表明,北方冬季农村供暖用煤总量大,利用效率低,其生活用煤产生的烟尘总量相当于工业用煤的2.7倍,加之村落人口密集,室内通风条件差,故现有的供暖形式对人体健康危害很大。针对供暖方式的研究,我们提出了在农村推行集中供暖的方案。

Impacts and Solutions of Northern China Winter Rural Heating on PM2.5

In order to study the impacts of north China winter rural heating on PM2.5,this paper conducted a survey for one and a half years in parts of rural areas of northern China.The results show that the winter heating consume a huge amount of coal at a low utilization rate and the dust generated by civil use is 2.7 times of the industrial coal.The existing heating method does great harm to human health,with the dense village population and poor indoor ventilation conditions.Focused on current heating mode,this paper puts forward a central heating scheme for rural areas.
