Printingenterprises are one of the main sources of generation and emission of VOCs, and also one of the important generators of hazardous waste. Tianhe Branch of Guangzhou Municipal Bureau of Ecology and Environment explored the practice of "three-book account management andprinting" through study and research, practical exploration and in-depth summary, identified the focus of the whole process supervision of printing enterprises, and effectively improved the efficiency of ecological and environmental law enforcement .
The source of "raw and auxiliary material ledger". The "raw and auxiliary material ledger" mainly registers the product names, serial numbers, VOCs content ratio, purchase volume, storage volume, usage volume and other information of various inks , organic solvents and other materials, and attaches the purchase contract and the chemical safety of the products. Original materials such as technical specifications (MSDS) or VOCs content test reports, warehouse entry and exit vouchers, etc.
"Exhaust gas treatment facility operation and maintenance ledger" management process. Printing enterprises in Tianhe District generally adopt activated carbon adsorption method, UV photo-oxidation catalytic method, microbial absorption method, water spray adsorption method and other methods to support the construction of exhaust gas treatment facilities. The "Exhaust Gas Treatment Facilities Operation and Maintenance Account" records the exhaust gas treatment facilities Daily start-up and shutdown time of equipment, power consumption (water), replacement or addition of activated carbon (UV lamps, microorganisms), equipment abnormality or temporary outage, etc.
"Hazardous Waste Ledger" tube end. The "Hazardous Waste Register" registers information on the generation, storage, transfer and disposal of hazardous waste such as waste ink, waste organic solvent, waste ink tank (box), waste cleaning agent barrel, waste activated carbon and waste UV lamp tube.
By checking the above-mentioned "three ledgers", law enforcement officers can grasp the specific content of VOCs in the raw and auxiliary materials purchased by the printing company from the source, and clarify whether the raw and auxiliary materials used by the enterprise meet the clean substitution of raw and auxiliary materials in the printing industry in Guangzhou Requirements; At the same time, it can judge whether there are environmental violations such as abnormal operation of waste gas treatment facilities and smuggling of waste gas during the operation of the enterprise, and grasp whether the replacement frequency and quantity of consumables for the enterprise's waste gas treatment facilities meet the requirements of the specification; it can also basically grasp the hazardous waste of the enterprise Production, storage, transfer and disposal, etc. management status, by comparing with the management system data, can also determine whether the enterprise has any environmental violations in violation of hazardous waste management.
The relevant person in charge of the Tianhe branch said that the "three books of account management and printing" are the results of the detailed implementation of the "Guidelines for the Standardized Management of the Branch of the Guangzhou Ecological Environment Bureau" issued by the Municipal Bureau of Ecology and Environment. The epitome of the work of "one specific industry, one work guideline, one inspection point, and one checklist" has effectively promoted the enforcement work of the sub-bureau to be more strict, standardized, accurate and efficient.
