(1) Industry: industry is an important source of air pollution. The pollutants emitted into the atmosphere by industry are varied and complex in nature, including soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc. Some of them are soot, some of them are gases. Some of them are soot and some are gases.
(2) living stoves and heating boilers: a large number of urban civilian living stoves and heating boilers need to consume a large amount of coal, coal in the combustion process to release a large amount of dust, sulfur dioxide, carbon monoxide and other harmful substances pollute the atmosphere. Especially in the winter heating, often make the polluted areas filled with smoke, choking people cough, which is also a source of pollution can not be ignored.
(3) transportation: cars, trains, airplanes, ships are the main means of contemporary transportation, they burn coal or oil produced by the exhaust is also an important pollutant. Especially in the city of the car, the amount of large and concentrated, the emission of pollutants can directly invade the human respiratory organs, the city's air pollution is very serious, and become one of the major sources of air pollution in large cities. Automobile emissions mainly include carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, the first three substances are very harmful.
Countermeasures
1, to carry out regional exhaust gas special rectification. Completed the "cogeneration" project, centralized heat supply to 12 printing and dyeing enterprises, replacing 34 small boilers and 29 chimneys of the above enterprises; supervised the construction of the Ma Wan Power Plant 1 #, 2 #, 3 # units of desulphurization facilities; shut down 8 small oil-fired units. 3 industrial kilns were installed with on-line monitoring instruments for exhaust gases;
2, implemented the "Blue Sky Action", ordered the earth field, Shamkang stone field and other dust pollution enterprises, 9 smoke and dust exceeded the standard enterprises, uncovered dump trucks 416 times for rectification and management, effectively curbing the exhaust gas pollution.
3, comprehensively deepen the prevention and control of motor vehicle exhaust pollution, the initial establishment of a more scientific and reasonable motor vehicle emission control system and long-term regulatory mechanism. New cars strictly implement the environmental protection model catalog management, strengthen the supervision of vehicles in use. It has deepened the environmental protection classification and labeling system, and made it mandatory to add automotive fuel detergents to gas stations in the city. Carrying out research and development and demonstration operation of hybrid and other clean vehicles, establishing the first commercial operation demonstration line of hybrid buses in the province in Longgang, and initiating the feasibility study on the use of hybrid vehicles in cabs and official vehicles. Increased publicity on the prevention and control of motor vehicle exhaust pollution, compiled the Environmental Protection Handbook for Vehicle Owners, and strengthened training for drivers of public transportation operations. Throughout the year***, 34,940 motor vehicles were inspected, and 5,742 vehicles were found to have exceeded the standard.
4, to carry out the work of the Smoke Control Zone, the annual monitoring of boilers, kilns, large stoves and other smoke exhaust facilities used in the districts, to ensure that the emission standards are met.
