摘要
印刷行业是挥发性有机物(VOCs)的重要排放源之一,为了全方位地推进印刷行业VOCs治理工作,各印刷企业积极开展"源头替代、过程严控、末端治理"三管齐下的治理方案.末端治理作为VOCs治理的技术性手段,对VOCs减排水平起到至关重要的作用.结合印刷行业VOCs产生及治理措施,以河北省石家庄市某印刷企业为例,由于该企业排放的VOCs主要为乙酸乙酯和乙酸正丙脂,故采取增设光解催化氧化法+活性炭吸附设备的方案,对VOCs排放进行治理.实践检测证明,该方案在设备正常运行时,VOCs处理率为97.25%,满足VOCs排放要求.
Abstract
The printing industry is one of the important sources of volatile organic compounds(VOCs)emissions.In order to comprehensively promote the governance of VOCs in the printing industry,various printing enterprises actively carry out a three pronged governance plan of"source substitution,process strict control,and end treatment".End of pipe treatment,as a technical means of VOC treatment,plays a crucial role in reducing VOC emissions.Taking a printing enterprise in Shijiazhuang City,Hebei Province as an example,based on the generation and treatment measures of VOCs in the printing industry,the scheme of adding photocatalytic oxidation method and activated carbon adsorption equipment is adopted to treat VOCs emissions,as the VOCs emitted by the enterprise are mainly ethyl acetate and n-propyl acetate.Practical testing has proven that the VOC treatment rate of this scheme is 97.25%when the equipment is operating normally,meeting the VOC emission requirements.
