The Ministry of environmental protection issued five new standards for pollutant discharge
Learned from the Ministry of environmental protection, to implement the State Council "air pollution prevention action plan" and "water pollution prevention action plan", through the transformation and upgrading of the formulation and revision of emission standards in key industries "forced" industry, the Ministry of environmental protection jointly with the State Quality Inspection Administration formulated the "ship launch limits and measurement methods for exhaust pollutants from the first (China two)", "stage, motorcycle emission limits and measurement methods (fourth Chinese stage)", "light motorcycle emission limits and measurement methods (fourth Chinese stage)", "light hybrid electric vehicle pollutant emission control requirements and measurement methods" and "caustic soda, PVC industrial pollutant emission standards" five national pollutant emission standards.
Ministry of Environmental Protection Technology Standards Department Director Zou Shoumin said that the implementation of these five criteria can substantially reduce particulate matter (PM), nitrogen oxide (NOx), sulfur dioxide (SO2) pollution, promote technological progress and improve the environmental quality of the industry.
Zou Shoumin said that China is a country with rich inland waterway transport resources, the problem of environmental pollution has become increasingly prominent, especially in port cities, rivers and coastal cities. In view of the urgent situation of China's ports and ship air pollution control, environmental protection ministry formulated the emission standard of ship engine emission control, strengthen the ship pollutant emission standard of air pollutants, fill the blank of ship.
The new standard applies to China registry in China waters or operations (such as inland ships, coastal ships, Jianghai direct ship, the ship and all kinds of fishing net rated power) with more than 37 kilowatts, the new production of marine environmental management of the engine, is not suitable for ocean shipping. The relevant provisions of the international convention of shipping execution. In addition, the standard also provides for the requirements of the use of fuel and ship and ship after the implementation of major overhaul emissions requirements. After the implementation of new standards, marine engine emission levels of pollutants will be significantly reduced, according to an annual increase of 10 million kilowatts ship life, for a period of 25 years, the implementation of the first phase of the standard 3 years, the ship manufacturing machine is put into use in the whole life period of the NOX emissions of about 1 million 400 thousand tons, about 400 thousand tons of PM; if the implementation of the second the stage for 3 years, with the vessel ship machine in its life period will be further NOX emissions of about 1 million 150 thousand tons, about 60 thousand tons of PM. Pollution reduction effect will be more significant if all inland waterway, coastal and fishing vessels meet the requirements of the standard.
Zou Shoumin said that China's rapid growth in the motorcycle industry, as of the end of 2015, the number of motorcycle ownership reached 95 million 140 thousand. According to estimates, in 2015 the proportion of motor vehicle emissions in the country accounted for the proportion of motor vehicle emissions: carbon monoxide (CO) accounted for 12.7%, hydrocarbons (HC) accounted for 13.5%, NOx accounted for 1.6%. Although our country is a big country in the production and use of motorcycle, but the overall level of the motorcycle technology and the international advanced level there is still a significant gap. In order to effectively control the pollution of the motorcycle and promote the technical progress and structure optimization of the related industries, the Ministry of environmental protection formulated the four standard of motorcycle and portable motorcycle.
Compared with the third stage of the current standard, major revisions in five aspects: one is to expand the scope of the standard, the new diesel motorcycle emission control requirements; two is the new pollution projects, the new particle control requirements for diesel tricycle; three is the pollutant limits further tightened; the four is to further enhance the requirement of durability of emission control; five is the request of more perfect environmental management and technology.
Zou Shoumin pointed out that since July 1, 2019, all new sales and registration of motorcycles and light motorcycles should meet the requirements of the new standard. In the implementation of 3 years of national four standard estimates, the new production of all motorcycles during its entire service life will be less than the implementation of the three standard CO emissions of about 6 million 500 thousand tons, about 2 million tons of HC emissions, NOx emissions of about 300 thousand tons.
Zou Shoumin said that in recent years the countries actively encourage the development of energy-saving, including hybrid electric vehicles and new energy vehicles, and as the technology continues to develop and mature, from the beginning of 2014, China's hybrid electric vehicle production and sales increased significantly, and with the continuous upgrading of China's automobile fuel consumption and emission standards, the automobile production sales growth will remain. Due to the auxiliary power, the traditional method can not accurately judge the emission of pollutants in the hybrid electric vehicle, so it is needed to establish a special measurement method for the discharge of pollutants.
The new standard is to "light hybrid electric vehicle emissions measurement method" (the revised provisions of the pollution control requirements and methods of measurement, light hybrid electric vehicle emission limits the implementation of emission standards for light-duty vehicles the corresponding section of the specific requirements of the project, the control of pollutants. "Light hybrid electric vehicle light hybrid electric vehicle emissions measurement method" is only applicable to the two stage, environmental management of light hybrid car new standard is applicable to the four, the five phase of the country. The implementation of the measurement method standard will not bring the cost of additional vehicle technology upgrade.
Zou Shoumin pointed out that in recent years, China's caustic soda and PVC enterprises have grown in size, has become the largest producer of caustic soda and polyvinyl chloride. The industry not only discharges conventional environmental pollutants, but also discharges heavy metals and other toxic and harmful pollutants, endangering human health and environmental safety. PVC industry belongs to the "Minamata Convention" the focus of governance involving mercury industry, industry annual mercury consumption of about 850 tons, accounting for about 85% of domestic consumption accounted for 51% of global consumption.
The status, production and emission control of domestic industry production process and pollutant emission control technology development and standards of economic costs and other factors to consider in the new standards, increase the air pollutant emission control requirements, adjust the water pollutant emission control project, tighten the control requirements of water pollutant discharge, cancelled in accordance with the provisions of sewage to classification management the. After the implementation of the new standard, is expected to wastewater chemical oxygen demand (CODCr), five, biochemical oxygen demand (BOD5), total mercury and chlorine emissions and the implementation of the existing standards, respectively, 77%, 67%, 67% and 87% respectively. Emissions of waste gas particulate matter, vinyl chloride, and non methane total hydrocarbon emissions were reduced by 51%, 72%, 58%, respectively, compared with the current standard.
