Furniture Factory 4 environmental

[Editor's note] Furniture production process will often release a variety of pollutants, such as air pollution, dust pollution, etc., which will bring a number of furniture manufacturing practitioners physical harm. However, the good news is that the environmental protection department is stepping up its efforts to screen the environment. Will the remediation strength bring benefits to manufacturing practitioners and consumers?
Articles made in the consumer and consumer goods industry network, edited by the billion Europe home for the industry reference.

Wood-based storage, sawing, machine engraving, scraping (sand) light and other processes produce dust, paint, drying and other processes produce volatile organic compounds, and these landless wood chips, dust, no control of volatile organic compounds ... ... was the focus of the fire department to prevent fire-induced furniture companies, the main cause of fire has now become more serious blow to the environmental protection department of the blowhole.
Environmental protection department said that in order to strictly control the PM2.5, PM10, TSP and other furniture in the production of air pollution caused by health hazards and practitioners, furniture manufacturing industry emissions of air pollutants emission control is the focus of the prevention and control of emissions, are taken All-round investigation, investigation will not miss any dead ends and details.
Investigation process, the main sources of dust pollution in the cutting area of timber, wood processing workshops, paint grinding workshop, white stubble polishing area, the factory sector and other environmental protection departments thorough investigation of the dead ends.
Among them, the specific dust emissions mainly exist in the opening, drilling, machining, sanding and polishing process.
Second, most areas of furniture "standard" in the provisions of the total VOCs emission interval ranged between 80mg / m3 - 40mg / m3, in some areas to adopt a more stringent concentration limits.
Furniture manufacturing coating process to use more oily coatings, mainly polyurethane coatings, nitro coatings, alkyds, etc., the general business of the top paint spray paint shop in order to ensure the finish are clean closed spray booth, and the end Paint, paint process Although there are independent spray booths, but due to poor finish on the spray surface, most enterprises are open spray paint room.
Relatively well-managed companies remove paint mist by installing filter cotton at the paint booth, while poorly managed businesses discharge directly through exhaust fans installed on the wall of the shop floor, with very poor environmental impact.
As a main part of VOCs emission process (including drying process), the coating process can directly cause the environmental protection department to seize, rectify and stop the fines due to the atmospheric pollution caused by the dilution and volatilization of coating raw materials.
In addition, from Dongyang EPA for mahogany furniture business pollution problems developed by the program, you can also learn more about mahogany furniture manufacturers existing environmental problems and rectification requirements:
1, prevention and control of wastewater pollution

The implementation of clean diverting, rain diverting. In the plant area, the production and management of products, sub-regions, sawdust wastewater, drying cooking wastewater, bleaching wastewater, mahogany leaching water and marsh landfill leachate are all collected into the wastewater treatment system and discharged after reaching the standard. Uncontrolled mahogany furniture enterprises discharged into the environmental wastewater must meet the "Integrated Wastewater Discharge Standard" (GB8978-1996) a level of standards; in principle, the management of enterprises should be preconditioned to meet the regulatory standards into the sewage treatment plant centralized treatment . At the same time, encourage enterprises to entrust qualified, capable third parties to collect and process.
2, air pollution prevention and treatment

1) boiler. Mahogany furniture concentration area to encourage the implementation of district heating and promote the use of clean energy. 6 tons of steam (6 tons of steam produced per hour) The following combustion boilers must be completely phased out before the end of December 2015. The new batch of boiler must meet the relevant requirements. Without centralized heating conditions, the desulfurization rate of the coal-fired boiler above 35t / h should be not less than 90% and the desulfurization rate below 35t / h should not be less than 60%, and the boiler air pollutant emission standard (GB13271 -2014) and total control requirements.
2) workshop dust. The process of dusting, woodworking, polishing and grinding should be installed. The workshop shall be equipped with a dust absorption device and discharged after it reaches the comprehensive discharge standard of air pollutants (GB16297-1996).
3) paint exhaust. Painting, painting and other organic waste gas production processes, the workshop must be installed exhaust gas treatment device, after the discharge of air pollutants reached the comprehensive discharge standards (GB16297-1996) emissions.
3, solid waste

The classification of solid waste collection, standardize disposal. The temporary storage of general solid waste and hazardous solid waste respectively meets the requirements of the Control Standard for Pollution from Storage and Disposal of Industrial Waste and the Control Standard for Pollution from Storage of Hazardous Waste. Including sawdust, scrap and other materials are not allowed to be piled in the open; waste paint drums that contain or are directly contaminated with paint residues are hazardous wastes and should be entrusted to qualified units for disposal.
4, noise

Low noise equipment, and reasonable layout. Silence noise reduction measures should be taken for high noise sources and daily maintenance of noise prevention and control facilities should be strengthened. Ensure that the factory noise reaches the industrial enterprises environmental noise emission standards (GB12348-2008).
