Ministry of Environmental Protection: Increase vehicle emissions control Major multi-city major traffic points will build remote sensing equipment to screen vehicles

The legendary "Clairvoyance" and "Shunfeng Ear" have already entered our daily environmental protection and safety supervision by modern scientific and technological means. In the future, we will add the "electronic nose" as an advanced technical means.


Although the environmental protection department has been increasing the pollution control of motor vehicles, it is still difficult for diesel vehicles and some high-pollutant gasoline vehicles to screen and identify whether they exceed the standard. However, with the introduction of advanced remote sensing technology, this problem will be solved.
“The Ministry of Environmental Protection will soon issue a draft of the work plan for the prevention and control of volatile organic pollutants during the“ 13th Five-Year Plan ”period, and set out the overall requirements for VOCs (volatile organic compound) pollution prevention and control during the“ 13th Five-Year Plan ”period. Regional emissions include Beijing, Tianjin and Hebei, the Yangtze River Delta, the Pearl River Delta, Wuhan and its surroundings, and central Liaoning and other areas with heavy air pollution. "

On June 13, during the "2017 Environmental Protection Industry Innovation and Development Conference", Liu Bingjiang, director of the Department of Atmospheric Environment Management of the Ministry of Environmental Protection, made the above statement when introducing the next focus of air pollution control.
Among them, in terms of prevention and control of motor vehicle pollution, Liu Bingjiang introduced that the Ministry of Environmental Protection is constructing remote sensing networks in "2 + 26" cities in the Beijing-Tianjin-Hebei region. At the end of the year, about 10 fixed remote sensing systems have been installed in the main traffic points of "2 + 26" cities Equipment, focusing on screening diesel vehicles and high-emission gasoline vehicles.
VOCs pollution prevention in key industries <br /> /> Recently, Huang Runqiu, deputy minister of environmental protection, revealed in an interview that there are currently four major difficulties in the prevention and control of air pollution in Beijing, Tianjin and Hebei, including:

High-pollution and high-energy-consumption industries have gathered in large numbers, and the output of major gas-related products in 6 provinces and cities accounts for 30% to 40% of the national total;
The number of "scattered and polluted" enterprises is large and extensive, and preliminary statistics show that there are about 60,000 "scattered and polluted" enterprises in "2 + 26" cities;
The energy consumption structure is irrational. Beijing, Tianjin and Hebei and the surrounding provinces and cities consume 1/3 of the country's coal;
The contribution of motor vehicle emissions is large, and motor vehicle ownership accounts for 28% of the country.
This year is the assessment year of the "Air Pollution Prevention and Control Action Plan" (also known as the "Article 10 of the Atmosphere"). Based on this, the Ministry of Environmental Protection further improved the air pollution control targets and issued the "Beijing-Tianjin-Hebei and surrounding areas 2017 air pollution control" working plan".
To this end, Liu Bingjiang introduced that in the next step, the focus of air pollution prevention and control will be promoted from comprehensive industrial control, prevention and control of volatile organic matter pollution, and clean coal loosening. Among them, in terms of industrial facilities reform, it will promote the upgrading of pollution control in metallurgy, building materials, coal-fired boilers and other industries. In the near future, it will comprehensively strengthen the control of fugitive pollution; strengthen the comprehensive management of VOCs, promote low VOCs content and products; Pollution control.
Han Yingjian, a researcher at the Vehicle Pollution Monitoring Center of the Ministry of Environmental Protection, said that the treatment of VOCs involves many aspects, among which motor vehicles are one of the key points, especially the gas recovery at gas stations varies widely across Beijing, Tianjin, and Hebei, and law enforcement must be strengthened to achieve unity.
The environmental protection monitoring of motor vehicles will be strengthened. In 2016, the number of motor vehicles in China reached 295 million and the preliminary accounting of pollutant emissions was 44.725 million tons. Motor vehicle pollution has become an important source of air pollution in China and an important cause of fine particle and photochemical smog pollution. As a key area of air pollution, the number of motor vehicles in Beijing, Tianjin, Hebei, and the surrounding provinces is 80 million, of which 2.6 million are heavy vehicles, accounting for 28% of the country's total. A country III heavy-duty diesel car has the same pollutant emissions as 200 country IV cars.

Compared with the problem of the large number of motor vehicles in Beijing, Tianjin, Hebei and the surrounding areas, the problem of excessive emissions of motor vehicles has caused more social concern. During a heavy polluting weather in Beijing last October, the Ministry of Environmental Protection and the Beijing Municipal Environmental Protection Bureau jointly conducted road inspection sampling tests, and the results showed that vehicles exceeding 10 years of age had a higher rate of exceeding standards; taxis with mileage exceeding 300,000 kilometers The emission rate exceeds 80% ~ 90%.
According to Liu Bingjiang, in order not to affect the normal traffic and reflect the actual emissions of motor vehicles, the Ministry of Environmental Protection is constructing a remote sensing network in "2 + 26" cities in the Beijing-Tianjin-Hebei region. At the end of this year, all major traffic points in "2 + 26" cities will be installed Ten or so fixed remote sensing devices cover the main crossings where high-emission vehicles pass, with a focus on screening diesel and high-emission gasoline vehicles.
In response to this, Han Yingjian said that from the perspective of in-use vehicles, gasoline vehicles are mainly taxis, and national and national standard vehicles. Due to their long service life, exhaust gas purification devices are more damaged, and owners generally replace less actively , The probability of exceeding the standard is relatively high. Diesel cars The cars before the National III were yellow-labeled, and all requirements were eliminated. Although the national third and fourth standard vehicles do not need to be eliminated, the emissions are not very satisfactory, especially the national third cars do not have any exhaust environmental protection devices. It depends on the engine maintenance. If the maintenance is not in place, there will still be some emissions from Guosan vehicles.
Yan Ziqing, executive director of the Chinese Academy of Environmental Sciences, revealed that the current methods of testing vehicles are not uniform, the emission standards of new vehicles are not synchronized with the standards of in-use vehicles, the management of motor vehicle testing agencies is not standardized, and the accuracy, repeatability and consistency of test data are low. It is impossible to grasp the amount of pollution emissions by issuing a qualified mark management. Many problems have caused insufficient technical support for the government's control of pollution by current vehicle emissions detection and related measures.
