集中供热工程实施前后黑碳气溶胶排放的对比分析

Comparative Analysis of Black Carbon Aerosol Emissions before and after the Implementation of the Central Heating Project

燃煤烟尘中的黑碳气溶胶不仅会导致区域气候变化,还会影响大气环境质量和人类健康,已成为近几年研究的热点问题。本文以定西市新城区集中供热工程为例,利用公式法和污染源清单法对集中供热和分散供热两种供热方式产生的黑碳气溶胶进行了量化计算,用以说明集中供热工程的实施产生的环境效益。结果表明,集中供热对改善或减少黑碳气溶胶的排放量、保护大气环境质量、减少大气污染起到了重要的作用。

Black carbon aerosol in coal soot and dust not only causes the change of climate system energy, but also affects the quality of atmospheric environment and human health, so it is one of the very popular research topics in recent years. This paper takes the central heating project in the new urban area of Dingxi City as an example, quantitatively calculates the black carbon aerosol emission of the central heating project and the decentral heating project by using formula method and pollution sources list method to demonstrate the great environmental benefits of the central heating project. The results show that the improvement of central heating plays an important role of reducing the emission of black carbon aerosol, protecting atmospheric environment quality and reducing air pollution.
