At present, the environmental protection issue is the printing industry is particularly concerned about the key topic. In this context, April 28, Beijing printing enterprises environmental management laws and regulations training held in Beijing. Industry associations, industry experts, business executives on the current printing enterprises facing environmental protection situation, the printing industry volatile organic matter emission standards and other topics to explore the implementation of environmental governance, for the Beijing's clear water and blue sky out of a force.
 
Policies and regulations to establish standards for production
 
Beijing from March this year, will continue to carry out a year of "special air law enforcement week" to upgrade to "joint law enforcement week", based on daily law enforcement, the use of a week to carry out multi-sectoral joint law enforcement action. The Joint Law Enforcement Week, launched in March this year, was the first "Joint Law Enforcement Week" in 2015 in Beijing. The "joint law enforcement week" period, the city's environmental protection, urban management departments to check all kinds of pollution sources 1056 units. Environmental protection departments to file a penalty for illegal units 61, the amount of punishment to be 138 million, all the illegal units of exposure. Among them, Beijing Hengjia Printing Co., Ltd., Beijing Canaan Printing Co., Ltd. two printing enterprises were "dangerous waste problem" "abnormal operation of environmental protection facilities" by the case on file punishment.
 
For the printing industry, environmental pollution problems, in recent years, Beijing Municipal Environmental Protection Bureau in conjunction with the relevant departments of Beijing to develop specific policies and regulations. In the elimination of backward technology, the Beijing Municipal People's Government on the issuance of the Beijing Municipal Economic and Information Commission, the Municipal Environmental Protection Bureau to develop the "Beijing industrial pollution industry, production process adjustment and equipment out of the directory (2014 version)", which involves There are four backward processes that need to be eliminated in the printing industry. They are plastic printing processes using benzene and ketone organic solvents, screen printing processes and lead, lead printing and gravure printing using aniline inks.
 
In carrying out cleaner production, the Beijing Municipal Development and Reform Commission, the Municipal Finance Bureau and the Municipal Environmental Protection Bureau jointly issued the Measures for the Administration of Cleaner Production in Beijing. According to reports, Beijing to 2017, 36 printing companies need to carry out cleaner production audit, is now more than 10 companies to carry out or is being carried out. For the implementation of the unit through the audit assessment, enjoy the audit fee subsidies.
 
At the same time, the Beijing Municipal Bureau of Finance, the Municipal Environmental Protection Bureau, the Municipal Economic and Information Technology Commission, the Municipal Development and Reform Commission also issued the Beijing "air pollution control technology transformation project incentive fund management approach" to encourage enterprises to carry out environmental protection technology.
 
In the development of emission standards, the Beijing Municipal Environmental Protection Bureau is developing the "printing industry volatile organic matter emission standards", which provides the printing production activities in the volatile organic matter emissions control requirements, as well as the "standard" implementation and supervision and other relevant provisions. Printing production activities refers to the use of lithography, letterpress, gravure printing, paper, plastic, metal, glass and ceramics and other materials for the printing of prepress, India, India and other production activities.
 
Beijing Municipal Environmental Science Research Institute Wang Minyan introduction, the "standard" will be introduced this year, the relevant pollution charges will be promulgated. The preparation of the "standard" embodies the following three principles: to reflect the whole process of pollution prevention thinking, not only consider the end of the treatment of pollutants and disposal; reference value set to consider the domestic level of existing technology and management level, and a certain incentive ; Focus on practical and operational, try to choose the printing industry production sector, statistical management and health, safety and environmental management departments daily use of indicators.
 
"Shadow killer" VOCs to seize the PM2.5 source clear powers and responsibilities
 
Why are printing companies classified as key polluting enterprises? The reason is that VOCs (ie, volatile organic matter) "to blame." According to reports, in 2013, China's average haze days for the most 52 years, 104 cities severe "fall." Three major economic circles, the Beijing-Tianjin-Hebei region more than 100% of air pollution standards, the Yangtze River Delta region exceeded 60% of the total. While the Pearl River Delta region exceeded 20%. The main pollutants are PM2.5 and ozone, and VOCs are the main precursor material for the formation of PM2.5 and ozone (ie, the first stage of a metabolic intermediate).
 
What is the current level of VOCs emissions in the printing industry? According to the results of the Beijing Industrial Source Inventory in 2014, the emissions of VOCs in the printing industry in Beijing were 5354 tons, accounting for 17% of the total industrial emissions (excluding the petrochemical industry). There were 73 enterprises with set up waste treatment facilities , Accounting for 7.4% of the printing industry. For the printing of printing companies, ink, cleaning agents, fountain solution as the main source of emissions; for packaging and printing enterprises, the ink, composite rubber is the main source of emissions. The distribution of VOCs in the printing business of a publication shows that 41% of the ink, 27% of the cleaning fluid, 18% of the fountain solution, 8% of the varnish and 6% of the adhesive. Wang Minyan introduction, the printing business VOCs emissions for the majority of the form of non-organized escape, so the focus of the printing industry is the source control and process control. The focus of future law enforcement will also be on the technical measures and management requirements.
 
Wang Minyan that the printing industry emissions of air is characterized by large air volume, low concentration, relative to the supporting waste gas treatment equipment into large, high energy consumption, low economic efficiency. At present, in the printing industry more widely used adsorption recovery technology, adsorption enrichment technology, thermal combustion technology, catalytic combustion technology, plasma technology.
 
Wang Minyan analysis, the input of VOCs, the printing industry should be made of organic raw materials VOCs content limit requirements. Control VOCs input, and reduce potential emissions. In the VOCs organized emissions, clear the major VOCs emissions sectors, the use of VOCs containing raw and auxiliary materials must be installed VOCs purification equipment; for VOCs control equipment, put forward operation and maintenance requirements to ensure the stable operation of purification equipment; improve the sampling of organized emissions Methods to improve the scientific and reliability of monitoring results. For waste residue, VOC-containing waste disposal requirements should be proposed to reduce potential emissions. In view of the problem of non-organized fragmentation of VOCs, it should change the control mode, set the unorganized monitoring point, propose the non-organized monitoring point limit requirement, reduce the unorganized emission.
 
In the hazardous waste environmental management, the Beijing Municipal Environmental Protection Bureau of solid waste and chemical management center Huang Hailin introduction, production and waste units common violations are: management system is not perfect, pollution control measures and contingency plans; not declare, not truthfully declare No storage of facilities, hazardous waste open-air, mixed with domestic waste; hazardous waste commissioned by non-qualified units to collect, transport, use, the use of non-qualified, non-certified, And disposal; random discharge, disposal of hazardous waste; transfer of hazardous waste does not run the transfer of the single.
 
Industry supervision efforts to increase targeted
 
"Beijing Printing Association of Beijing printing enterprises in the environmental management will be incumbent." "We have a common name, that is, 'India', therefore, must join hands and forth." Beijing Printing Association, said Ren Yucheng. After the Beijing Printing Association and the Beijing Municipal Environmental Science Research Institute lasted nearly a year of research, the conclusion is: lithography enterprises and gravure printing enterprises of the most prominent pollution sources.
 
Ren Yucheng said: "lithographic printing process of washing water, fountain solution and some auxiliary materials will be discharged from the source, relative to lithography, gravure printing pollution sources are very serious, the use of ink need to dilute the solvent, and even solvent pollution Emissions are more than the ink, which has resulted in an increase in emissions from the printing industry, which is what needs to be taken into account in the future.
 
According to incomplete statistics, in 2014 at least 10 printing enterprises by the municipal environmental protection department punishment. Recently, Beijing Jiazheng Tongda Cardboard Packaging Co., Ltd. coal-fired boiler flue gas emissions exceeded, Xinhua News Agency Printing Co., Ltd. in the printing process in the production of waste ink barrels and other waste ink containing the "National Hazardous Waste List" in the dangerous Waste, the storage site is not set by the provisions of hazardous waste identification signs, both by the Beijing Municipal Environmental Protection Bureau of the administrative penalties.
 
Ren Yucheng said that the recent environmental problems in the printing industry by the unprecedented concern, the Beijing Printing Association will increase the intensity of the Indian printing industry supervision. Recalling 2013, the Beijing Municipal Environmental Protection System has adopted daily inspections and special operations to strengthen the supervision of the volatile organic emissions of the printing industry, 36 printing enterprises due to the existence of non-installed or abnormal use of waste treatment facilities, in violation of the construction project "three simultaneous "And the acceptance system, by the environmental protection department punishment.
 
As the Beijing Municipal Environmental Science Research Institute to undertake a number of Beijing policies and regulations of the revised work, familiar with the contents of Beijing's environmental policy and direction, to this end, Wang Minyan said the hospital familiar with all kinds of VOCs control technology and applicability, understanding of the printing industry Process characteristics and characteristics of sewage, VOCs control technology can be completed screening and assessment, for enterprises to provide environmental protection policy support and effective emission reduction programs.
