During Oscar Wilde's "Twelve-Five" period, the "new member" was expected to be added to the pollutant binding index (Fang Xuyan).  This reporter learned from the authoritative channels, is being drafted in the "Twelve-Five" environmental planning, there have been two "total control of the implementation of" new indicators, namely, ammonia nitrogen and nitrogen oxides, the two substances are water pollutants and air pollutants in the "large".  Specific mitigation indicators have been formulated, the total amount of ammonia-nitrogen emissions control target is 10% less than 2010, the key industries and key areas of NOx emissions than in 2010 reduced by 10%. "In terms of pollutant control, we are moving from a single pollutant control to a multiple pollutant control." This will greatly improve the environmental protection threshold of high energy consuming enterprises and improve the environmental quality to a certain extent.  An official at the Ministry of Environmental Protection said to reporters. The reporter learned that, compared to ammonia nitrogen, nitrogen oxides control situation will be more complex, difficult.  Because of the air pollution in China's urban agglomeration, it is transforming from soot-type to soot-type and motor vehicle exhaust pollution.  If you want to complete NOx reduction targets, a number of air pollution management experts suggest that during the "Twelve-Five" period, should carry out the power industry compulsory denitration pilot, and in the automotive air pollution problems highlighted key cities, the total amount of motor vehicle ownership control pilot.  Multi-pollutant control put on the agenda Zhao Hualin, director of the Ministry of Environmental Protection, said publicly that the "Eleven-Five" period of pollutant emission reduction achieved a phased outcome, China's local environment has improved, but the overall deterioration of the environment is still continuing. "In the present circumstances, the completion of the ' Eleven-Five ' period of sulphur dioxide (SO2) and chemical oxygen demand (COD) emissions reduction targets should not be very difficult, but the environmental problems remain outstanding." Ammonia nitrogen and the high emission of oxides, to some extent, offset the effect of cod and sulfur dioxide emissions.  "A local environmental system official confessed to reporters.  In fact, the impact of "environmental quality" is a series of pollutants, only by restricting sulfur dioxide and chemical oxygen demand is difficult to bear fruit. Taking the treatment of water pollution as an example, by controlling the total amount of cod, the cod is decreasing, but the phenomenon of ammonia-nitrogen exceeding in water is increasingly outstanding.  In recent years, the Bulletin of Environmental quality shows that ammonia nitrogen in surface water has gradually become the most important pollution project, even exceeding the chemical oxygen demand has become the primary index to affect the quality of surface water environment. This situation also exists in the treatment of air pollution.  Satellite monitoring found that 2006 years later in China, the SO2 began to decline sharply, down about 20%, but the concentration of nitrogen oxides in the air increased, resulting in acid rain and haze phenomenon did not reduce, some areas have become more serious. Taking Jiangsu province as an example, the frequency of acid rain in some areas is still high, because nitrogen oxides are not effectively controlled, the type of acid rain changes from sulfuric acid type to nitric acid type.  The incidence of acid rain in the first half of 2010 reached its highest in nearly 4 years. In this case, it is necessary to incorporate ammonia nitrogen and nitrogen oxides into total control. "This at the same time indicates that the state wants to improve the ringThe quality of the force, otherwise can not achieve the 2020 environmental well-off goal.  "said the former official of the Ministry of Environmental Protection to reporters.  Ammonia nitrogen into the total control, will be in the chemical and chemical products manufacturing, non-ferrous metal smelting and rolling processing industry, petroleum processing coking and nuclear fuel processing, agricultural and food processing industry, textile industry, leather fur Feather (velvet) and its products industry, beverage manufacturing, food industry, the 8 industries have a significant impact. According to the "China's first national census Bulletin" published in early 2010 (hereinafter referred to as "Bulletin"), the above 8 industries accounted for 85.9% of the total ammonia-nitrogen emissions from the industrial wastewater plant.  This also means that some of these ammonia-nitrogen emissions are substandard or difficult to meet the small and medium-sized enterprises, will be forced to shut down, stop production or conversion.  The power industry or mandatory denitration and ammonia nitrogen emission reduction targets are different, NOx emission reduction targets more "key industries and key areas" restrictions. "In a sense, NOx pollution is not a national problem, but should be localized in regional issues, after all, in addition to the eastern region, the central and western regions of the nitrogen oxides pollution problem is not outstanding."  "Wang Jinnan, chief engineer of the Environmental Planning Institute, said publicly. The reporter learned that the so-called key areas are mainly concentrated in the Yangtze River Delta, Pearl River Delta, Beijing-Tianjin-Hebei and Chengdu-Chongqing and other regions, and the so-called key industries, according to the bulletin shows relatively high NOx emissions industries, mainly concentrated in the production and supply of power heating, non-metallic mineral products industry ferrous metal smelting and calendering processing industry, Chemical raw materials and chemical products manufacturing, petroleum processing coking and nuclear fuel processing industry in these 5 industries.  Among them, the electric power industry mainly. "Therefore, in the industrial sector to treat nitrogen oxides, mainly in the electricity industry to be out of stock." "The previous scholars to the reporter analysis," and the current emission of nitrogen oxides of electricity emissions are relatively low standards, to be improved.  "The reporter learned that the 2004 implementation of the" Thermal power plant air pollutant emission standards (GB13223-2003), according to the time period and fuel characteristics of the coal-fired, fuel boiler nitrogen oxide emission limits, but this principle is based on low nitrogen combustion technology can achieve emissions levels. "If this is the standard, 10% of the cuts must be difficult to achieve."  "A power industry worker, who declined to be named, told reporters.  In this respect, Zhu Fahua, deputy director of the Institute of Environmental Protection, said in the media, nitrogen oxides can learn from the power industry forced desulfurization experience, the pilot forced denitration.  He suggested that, in addition to Xinjiang, Tibet and other regions in the remote areas, all new 100MW of coal-fired units (including thermoelectric units) NOx emission standards should be strictly to 200mg/m3, that is, on the basis of low nitrogen combustion, the simultaneous installation of flue gas denitration device. The corollary policy of compulsory out-of-stock is also indispensable. "The power industry desulfurization effect is good, because there is a tariff subsidy policy, that is, the installation of desulfurization facilities, the internet price in the current on-grid electricity price per kilowatt hour increase of 0.015 yuan in the desulfurization plus subsidyPolicy。 "A worker at an environmental engineering company in Chongqing said," Mandatory denitration should also have ancillary subsidies, otherwise enterprises can not be on the denitrification facilities.  At an industry forum held at the end of last year, Peng, deputy Inspector of the National Development and Reform Commission, said the national Development and Reform Commission is working on economic policies and tariff policies for denitration.  Motor vehicle emission standards increase in addition to the industrial emission sources of power plants, vehicles in the source of life is also a key source of NOx emissions. According to the bulletin, 30% of the nitrogen oxides in the atmosphere are emitted from motor vehicle emissions.  Data show that Beijing, Shanghai, Guangzhou and other motor vehicles in the top 40 cities, about 50% of NOx pollution from motor vehicle exhaust emissions, Shenzhen emissions of nitrogen oxides accounted for 56.4% of the city's emissions. This reporter was informed that the proposed "Twelve-Five" environmental protection planning, which also gave a solution to the idea.  That is, the state will carry out "Twelve-Five" period of "vehicle oil synergy" control means, that is, by increasing emission standards to reduce exhaust emissions, by improving the quality of fuel, reduce the concentration of nitrogen oxides in the tail gas. In terms of emission standards, the threshold for vehicle access will be increased. That is, prohibit the production, sale and registration of vehicles that do not conform to the National motor vehicle emission standards, and strictly enforce the old compulsory elimination system of motor vehicles, and continue to push the car "to replace the old" and accelerate the elimination of "Yellow tagged car".  2015 years ago all the elimination of Beijing-Tianjin-Hebei, Yangtze River delta, Pearl River Delta area, such as "Yellow tagged car." At the same time, a set of control schedules is shown in the planning draft. That is, since 2011, strict implementation of the national Ⅳ phase of motor vehicle emission standards. 2013, the country-wide heavy duty diesel vehicles strictly implement the national Ⅴ phase of motor vehicle emission standards.  During the "Twelve-Five" period, some key regions and cities implemented the national Ⅴ stage emission standard in advance. In addition to vehicle emission standards, the fuel quality of motor vehicles will also be strictly controlled.  The draft plan shows that, since 2011, the country-wide supplier of Ⅲ standard vehicle fuel, in Beijing-Tianjin-Hebei, Yangtze River delta, Pearl River Delta, the three major regional supply countries Ⅳ standard vehicle fuel, 2015 years ago, nationwide supplier of Ⅳ standard vehicle fuel, key regional supplier Ⅴ standard vehicle fuel.  Taking into account the rapid growth of motor vehicles, the National Environmental Planning Institute chief engineer Wang Jinnan has said that in the automotive air pollution problems highlighted the key cities, the total amount of motor vehicle ownership control pilot. Wang Jinnan's views have been recognized by renowned air pollution control experts and academician Kiggiming of Chinese Academy of Engineering. Kiggiming that the pilot cities should choose the number of vehicles to increase the rate of too fast, the traffic environment pressure huge tens of millions of people above the city.
