Recently, the Ministry of Ecology and Environment issued the “Technical Specifications for Application and Issuance of Pollution Emission Permits for the Furniture Manufacturing Industry” (HJ1027-2019) (hereinafter referred to as the “Technical Specifications for the Furniture Manufacturing Industry”), which comprehensively Promote the reform of the pollution discharge permit system in this industry. Therefore, the furniture industry must also apply for a national emission permit!
At the same time, according to the requirements in the “Classified Management Directory of Stationary Pollution Source Discharge Permits”, the furniture manufacturing industry needs to In 2019, we successfully applied for the national pollution discharge license. In addition, according to the “Technical Specifications for Application and Issuance of Pollutant Discharge Permits – Boilers” (HJ 953), units that have boilers discharging pollutants also need to apply for a national pollutant discharge license!
There are 5 medium categories from 211 to 219 in the national economic industry classification; some industries in 203 2032 (Manufacturing of wooden doors and windows), 2039 (manufacturing of wooden toys and custom furniture manufacturing of cork products and other wood products) and some industries in 243 shall refer to this standard.
Pollution production and discharge links and permitted pollutant discharge
The pollution production and emission links involved in the production process of the furniture manufacturing industry include base material processing, painting and construction Glue, assembly and other production units. Among them, the painting and gluing workshops produce the largest amount of pollutants. A total of 6 exhaust gas permitting factors were determined, including particulate matter, volatile organic compounds (non-methane total hydrocarbons), benzene, toluene, xylene, formaldehyde, etc.; a total of 6 wastewater permitting factors were determined, including 1 Category 1 pollutant involved in metal furniture (total nickel), and 5 second-category pollutants (pH value, chemical oxygen demand, ammonia nitrogen, suspended solids, five-day biochemical oxygen demand).
Difference between key points and general sewage outlets
The exhaust outlets of the coating and sizing workshops in furniture manufacturing sewage discharge units that implement key management are used as The main discharge outlet and the others are general discharge outlets, all subject to concentration control. The wastewater discharge outlets of furniture manufacturing sewage discharge units are set as general discharge outlets and concentration control is implemented.
Accounting emissions
This standard does not set the allowable emissions of the furniture manufacturing industry, but is based on the management of organized pollution control facilities. Requirements serve as a starting point to refine requirements for facility maintenance, ledger records, and management systems in technical specifications to strengthen the operation of pollution prevention and control facilities and improve the effect of pollutant emission reduction. At the same time, combined with the requirements of the “Volatile Organic Compounds Unorganized Emission Control Standard”, the quantifiable assessment and operable measures in the “Volatile Organic Compound Exhaust Gas Collection and Treatment System Requirements” will be implemented into the technical specification licensing management matters to improve the industry’s unorganized emissions. Pollutant collection capacity.
Requirements for self-monitoring frequency
Exhaust gas monitoring, focusing on management of non-methane total hydrocarbons, benzene, toluene, dioxins at the main emission outlets of pollutant discharge units Toluene and formaldehyde should be monitored every six months, and the general discharge outlets of key management pollutant discharge units and the exhaust gas discharge outlets of simplified management pollutant discharge units should be monitored once a year. The unorganized exhaust gas emissions under key management shall be monitored once every six months, and the unorganized exhaust gas emissions under simplified management shall be monitored once a year.
Wastewater monitoring, metal furniture manufacturing sewage unit phosphate tank or production facility workshop wastewater treatment facility discharge outlet The total nickel of the furniture manufacturing sewage discharge unit is monitored once a quarter; the chemical oxygen demand and ammonia nitrogen of the furniture manufacturing sewage discharge unit are monitored once a quarter, and the chemical oxygen demand and ammonia nitrogen of the comprehensive wastewater treatment facility discharge outlet are monitored once a year.
