北京市家具制造业涂料应用过程挥发性有机物排放现状及未来趋势

在调研北京市家具制造业涂料使用现状的基础上,采用排放因子法,分别自上而下计算北京市家具制造业挥发性有机物(VOCs)排放量,自下而上计算重点家具制造企业VOCs排放量,并采用情景分析法对未来北京市家具制造业VOCs排放情况进行预测。结果表明,2015年北京市家具制造业VOCs排放量约为1.37×10~4 t;重点企业VOCs排放量占比约29.4%。通过优化涂料品质使其达到欧美发达国家20世纪末期平均水平,且要求新建企业安装废气末端治理设施,该行业VOCs排放量可控制在1.15×10~4 t;进一步将涂料改进到欧美发达国家先进水平,且规模企业安装废气末端治理设施,该行业VOCs排放量可控制在8.80×10~3 t。对比分析两种控制措施的减排效果,提升涂料品质是控制VOCs排放的最有效措施。

Estimation and forecast of volatile organic compounds emitted from paint uses in Beijing furniture industry

The emission factor method was used to estimate the up to down volatile organic compounds(VOCs)emissions of Beijing furniture industry and the down to up VOCs emissions of the main furniture enterprises based on the current paint consumptions of furniture industry in Beijing.Furthermore,the scenario analysis method was used to forecast the VOCs emissions of Beijing furniture industry in the future.The results indicated that the VOCs amount emitted from furniture industry paint use was 1.37×10^4 t in 2015,while the key enterprises VOCs emissions accounted for about 29.4%.Two control scenarios were developed to evaluate the potential of VOCs emission reduction.VOCs emissions from furniture industry might be controlled at 1.15×10^4 t through the improvement of paints quality to the medium level of that in developed countries in late 20th century and installation of waste gas treatment equipments in newly built factories.VOCs emissions could be further reduced to 8.80×10^3 t if the paint quality would be improved to the current advanced level of that in developed countries and all factories would install waste gas treatment equipments.Comparing and analyzing the emission reduction effect of two control measures,improvement of paint quality was the most effective measure.
