This standard is formulated with a view to implementing the Environmental protection law of the People's Republic of China and the Law of the People's Republic of China on the prevention and control of atmospheric pollution, controlling environment pollution, improving environmental quality and enhancing technical progress and sustainable development for paint, ink and adhesive industry. This standard specifies the control requirements, monitoring and supervision of emission of air pollutants for paint, ink and adhesive industry. For emission of water pollutants, odor pollutants and ambient noise made by paint, ink and adhesive industrial enterprises or production facilities, related national standards apply; for identification, treatment and disposal of the generated solid wastes, national control standards for solid waste apply. This standard is issued for the first time. New facilities and existing facilities perform this standard for control of emission of air pollutants as of July 1, 2019 and July 1, 2020 respectively instead of GB 16297-1996 Comprehensive emission standard of air pollutants. Upon approval of provincial people's government, all regions may implement this standard in advance according to the need of local environmental protection and economic and technical conditions. This standard specifies the basic control requirements for emission of air pollutants in paint, ink and adhesive industry. Local provincial people's government may formulate local pollutant emission standards for the items not specified in this standard; and it may also formulate local pollutant emission standards stricter than this standard for the items specified in this standard. Annexes A and B of this standard are informative. This standard is formulated by the Department of Air Environment and the Department of Laws and Regulations and Standards under the Ministry of Ecology and Environment. This standard was approved by the Ministry of Ecology and Environment on April 16, 2019. This standard shall be implemented from July 1, 2019. The Ministry of Ecology and Environment is responsible for the explanation of this standard.

储罐附件开口（孔），除采样、计量、例行检查、维护和其他正常活动外，应密闭。 c） 定期检查呼吸阀的定压是否符合设定要求。 5.2.4.3 维护与记录 挥发性有机液体储罐若不符合 5.2.4.1 条或 5.2.4.2 条规定，应记录并在 90 d 内修复或排空储罐停止使用。如延迟修复或排空储罐，应将相关方案报生态环境主管部门确定。 5.3 VOCs 物料转移和输送无组织排放控制要求 涂料、油墨及胶粘剂企业 VOCs 物料转移和输送无组织排放控制要求应符合 GB 37822 规定。 5.4 工艺过程 VOCs 无组织排放控制要求 5.4.1 工艺过程控制要求 5.4.1.1 VOCs 物料的配料、投加、反应、混合、研磨、分散、调色、兑稀、过滤、干燥以及灌装或包装等过程，应采用密闭设备或在密闭空间内操作，废气应排至废气收集处理系统；无法密闭的，应采取局部气体收集措施，废气应排至废气收集处理系统。 5.4.1.2 移动缸及设备零件清洗时，应采用密闭系统或在密闭空间内操作，废气应排至 VOCs 废气收集处理系统；无法密闭的，应采取局部气体收集措施，废气应排至 VOCs 废气收集处理系统。 5.4.1.3 真空系统应采用干式真空泵，真空排气应排至 VOCs 废气收集处理系统。若使用液环（水环） 真空泵、水（水蒸气）喷射真空泵等，工作介质的循环槽（罐）应密闭，真空排气、循环槽（罐）排气应排至 VOCs 废气收集处理系统。 5.4.1.4 载有 VOCs 物料的设备及其管道在开停工（车）、检维修和清洗时，应在退料阶段将残存物料退净，并用密闭容器盛装，退料过程废气应排至 VOCs 废气收集处理系统；清洗及吹扫过程排气应排至VOCs 废气收集处理系统。 5.4.1.5 工艺过程产生的含 VOCs 废料（渣、液）应按照 5.2 条、5.3 条要求进行储存、转移和输送。 盛装过 VOCs 物料的废包装容器应加盖密闭。 5.4.1.6 企业应按照 HJ 944 要求建立台账，记录含 VOCs 原辅材料名称、使用量、回收量、废弃量、 去向以及 VOCs 含量等信息。台账保存期限不少于 3 年。 5.4.2 工艺过程特别控制要求 重点地区的企业除符合 5.4.1 条规定外，还应满足下列要求： a）高位槽（罐）进料时置换的废气应排至 VOCs 废气收集处理系统或气相平衡系统。
