摘要
利用物料衡算法,结合生产工艺调查、现场采样及实验分析,研究了广州市某典型日化企业生产过程中挥发性有机物(VOCs)从原料输入到产品输出各环节的排放特征。结果表明,有组织排放检测口的总VOCs质量浓度接近,其中柠檬烯成分质量浓度均为最高,而无组织采样点中原料混合区的VOCs质量浓度最高,其中柠檬烯成分质量浓度也是最高。有、无组织排放环节分别检测出11和16种主要的VOCs物种,经分析可知该企业的特征污染物为柠檬烯,且通过物料衡算得出该企业的VOCs综合排放因子为0.199 kg/t。
In combination with the production process investigations, field sampling and experimental analysis, the emission features of volatile organic compounds （VOCs） from raw material input to product output in the manufacturing process of a typical daily chemical enterprises in Guangzhou city were examined via material balance method. Results indicated that the mass concentration of VOCs of organized discharge detection port is basically identical. The mass concentration of VOCs of unorganized sampling at raw material mixing area is the highest. The mass concentration of limonene component is the largest both in organized discharge port and unorganized sampling. 11 and 16 kinds of main VOCs were detected in the organized discharge and unorganized emission respectively. The main pollutant of this enterprise is limonene. The comprehensive emission factor of this enterprise was 0. 199 kg/t based on the material balance method.
