摘要
为开展天津市挥发性有机物(volaitle organic compounds,简称VOCs)普查,修正天津市挥发性有机物排放因子,开展了滨海新区重点行业挥发性有机物调查工作,调查企业的原材料使用量、生产工艺、污染治理设施等情况,根据环保部制定的排放因子对被调查企业挥发性有机物排放量进行估算;分析估算结果,并与污普库估算数据及企业填报监测数据进行比对分析。发现估算结果较为准确,且滨海新区单一企业挥发性有机物排放量最大的为石油化工及储运行业,建议下一步重点开展石油化工及储运行业挥发性有机物治理及泄漏检测与修复技术,加强无组织源排放治理。
A full-scale survey for emission of volatile organic compounds（VOCs） and revision of VOCs emission factors was launched in all key industries in Tianjin Binhai New Area. The amount of raw materials used by different industries, production process, and pollution-control facilities were included in the survey. VOCs discharge for different enterprises was estimated based on the emission factor standards set by the Ministry of Environmental Protection. The estimation results were accurate after comparing with the governmental database and the reports of enterprises. Base on the analysis, the petrochemical industry and the storage and transportation industries were found as the major contributors of VOCs emission in Binhai New Area. Therefore, managing VOCs emitted by these particular industries, investigating new techniques to prevent leakage, and strengthening the supervision of unorganized emission sources were suggested to improve air quality in Tianjin.
