　　4.2.Production process control.

　　Raw and auxiliary materials containing VOCs should be kept airtight in the process of production, packaging, transportation, transfer, use and storage, etc. They should be opened at will during use and sealed in time after use to reduce volatilization.

　　Allocate (mixing, stirring, etc.), painting (spray, dip coating, spray coating, the roll besmear, brush besmear, coating, etc.), bonding (glue, hot pressing, composite, laminating, etc.), drying (drying and air drying, drying, etc.), clean (dip, spray washing, leaching, rinse and scrub, etc.) of VOCs such as process, should be carried out within the closed negative pressure in the workshop, and set up the exhaust pipe centralized collection import pollution control facilities for processing, and be in line with the relevant requirements of theVOC Unorganized Emission Control Standard (GB37822-2019).

　　Promote the use of electrostatic spraying, spray coating, roller coating, dip coating and other advanced technology.

　　4.3.Install efficient pollution prevention and control facilities.

　　Installation of pollution prevention and control facilities in furniture enterprises should include: exhaust gas collection facilities, exhaust gas treatment facilities and exhaust gas cylinder.

　　Waste gas collection facilities have an organic waste gas collection efficiency of no less than 80%.

　　The exhaust pipe shall be provided with a closed sampling port in accordance with theGuidelines for the Standardized Establishment of Pollutant Discharge Outlets in Guangdong Province (Yue Huan [2008] No. 42) and other requirements, in order to detect the concentration of organic waste gas before and after purification. There shall be no bypasses or waste gas leakage

　　The waste gas treatment facilities should be equipped with the functions of treating paint mist, filtering dust and highly efficient purification of organic waste gas, and can reflect the flow rate of waste gas, total VOCs concentration and total VOCs removal rate (in line with relevant national and provincial standards), so as to ensure the stable emission of waste gas up to the standard. VOCs removal rate should not be less than 50% in the process of using water-based coatings and other raw and auxiliary materials with low VOCs content. For processes using solvent-based raw and auxiliary materials, the VOCs removal rate should reach more than 80%. For furniture enterprises with a pre-purification voc emission rate of more than 2kg/h, the VOCs removal rate should reach more than 80%.

　　The height of the exhaust cylinder shall not be less than 15 meters in general. The exhaust pipe shall be provided with a closed sampling port in accordance with theGuidelines for the Standardized Establishment of Pollutant Discharge Outlets in Guangdong Province (Yue Huan [2008] No. 42) and other requirements, in order to detect the concentration of organic waste gas before and after purification. There shall be no bypasses or waste gas leakage

　　VOCs emission conforms to the relevant requirements ofGuangdong Provincial Volatile Organic Compound Emission Standard for Furniture Manufacturing (DB44/814-2010) and VOC Unorganized Emission Control Standard (GB37822-2019).

　　4.4.Standardize internal management.

　　Furniture enterprises should standardize internal management mechanism, establish ledger management system and operating rules according to actual production conditions, and define the replacement cycle of waste gas treatment consumables.
