我国工业VOCs减排控制与管理对策研究

对我国工业挥发性有机物（VOCs）排放进行了研究,其中包括工业VOCs的排放特征、控制现状与管理政策.我国工业VOCs具有排放强度大、波动范围宽、地域分布不平衡等特点,集中分布在京津地区、山东半岛、长三角和珠三角地区.现有的主流控制技术包括吸附回收、催化燃烧、蓄热燃烧、生物净化以及吸附浓缩/催化燃烧联用技术,污染控制的重点领域在石油化工、油气回收、造船与集装箱以及印刷、制药、皮革加工等行业.VOCs管理比较薄弱,相关的法律/法规/标准较少,监管尚不到位.研究认为VOCs治理应以重点区域、典型行业为对象,逐步推进,以实际削减量为目标,通过技术筛选、示范工程等途径,建立健全相关行业VOCs排放法规/标准,并辅助于相关的排放登记制度与分级收费制度,可有效减少VOCs的整体排放量.

Study on Control and Management for Industrial Volatile Organic Compounds (VOCs) in China

Volatile organic compounds (VOCs) emitted from industrial sources account for a large percent of total anthropogenic VOCs. In this paper, VOCs emission characterization, control technologies and management were discussed. VOCs from industrial emissions were characterized by high intensity, wide range and uneven distribution, which focused on Bejing-Tianjin Joint Belt, Shangdong Peninsula, Yangtze River Delta and the Pearl River Delta. The current technologies for VOCs treatment include adsorption, catalytic combustion, bio-degradation and others, which were applied in petrochemical, oil vapor recovery, shipbuilding, printing, pharmaceutical, feather manufacturing and so on. The scarcity of related regulations/standards plus ineffective supervision make the VOCs management difficult. Therefore, it is suggested that VOCs treatment be firstly performed from key areas and industries, and then carried out step by step. By establishing of actual reducing amount control system and more detailed VOCs emission standards and regulations, applying practical technologies together with demonstration projects, and setting up VOCs emission registration and classification-related-charge system, VOCs could be reduced effectively.
