How to reduce exhaust emissions
1, reducing pollution emissions
Reforming the energy structure, using pollution-free energy (such as solar energy, wind energy and hydropower) and low-pollution energy (such as natural gas), pretreating fuel (such as desulfurization before burning coal) and improving combustion technology can reduce pollution emissions. In addition, before pollutants enter the atmosphere, some pollutants in waste gas can be eliminated by dust removal and smoke elimination technology, condensation technology, liquid absorption technology and recycling technology, so as to reduce the amount of pollutants entering the atmosphere. Plant purification method, China has used plant sources for disinfection and sterilization for more than 3000 years.
2. Self-purification ability
Different meteorological conditions have different atmospheric capacity of pollutants, and the same pollutant discharge will cause different pollutant concentrations. For areas and time periods with strong wind, good ventilation, strong turbulence and strong convection, the atmosphere has strong diffusion and dilution ability and can accept more activities of factories and mines. In the area and time period of inversion, the diffusion and dilution ability of the atmosphere is weak, and it cannot accept more pollutants, otherwise it will cause serious air pollution. Therefore, effective emission control should be carried out in different regions and different time periods.
Step 3 start with yourself
Don't litter; Try to travel by bus and subway to reduce the use of private cars; Participate in greening activities such as tree planting; Private cars are equipped with tail gas treatment devices, and lubricating oil is used to fully burn fuel and reduce harmful gas emissions.
Reduce going out in foggy days (according to relevant explanations, ozone refers to ozone, while PM2.5 refers to fine suspended particles with a diameter less than 2.5 microns, also known as particles that can enter the lungs. This suspended particle is a "health killer" in the air. Extensive damage to respiratory system, heart and blood system).
Wear a mask when going out (mask material, service life, technical level and other factors are the criteria to define the quality of a mask. If consumers have no special needs, there is no need to snap up "concept masks" marked with various functions.
Cultivate some green plants indoors, such as chlorophytum.
Pay attention to cleaning (deeply clean the dust and bacteria in pores and protect the skin as the first line of defense).
Supplement nutrition, and properly supplement selenium through 100 micrograms. Selenium is a "natural antidote" to enhance resistance.
4. Industrial Zone
The site selection, chimney design, urban and industrial zone planning should be reasonable to avoid excessive concentration and repeated pollution of atmospheric emissions, resulting in serious pollution incidents in some areas. 5. afforestation
Dense forests can reduce wind speed and large particles of dust carried in the air. The surface of leaves is rough, some have fluff, and some can secrete mucus and oil, so they can absorb a lot of floating dust. Dusty leaves can continue to absorb dust after being washed by rain. Such reciprocating blocking and adsorption of dust can purify the air.
6, change the fuel composition
Implement coal to gas. At the same time, step up research and development of other new energy sources, such as solar energy, hydrogen fuel and geothermal energy. This can also greatly reduce the pollution of smoke.

Monitoring institutions shall use monitoring equipment that meets national standards and abide by monitoring norms. Monitoring institutions and their responsible persons are responsible for the authenticity and accuracy of monitoring data.
Article 40 The State promotes clean production and recycling of resources.
Relevant departments of the State Council and local people's governments at all levels shall take measures to promote the production and use of clean energy.
Enterprises should give priority to the use of clean energy, adopt technologies and equipment with high resource utilization rate and low pollutant discharge, as well as technologies for comprehensive utilization of wastes and harmless treatment of pollutants to reduce the generation of pollutants.
Article 42 Enterprises, institutions and other producers and operators that discharge pollutants shall take measures to prevent and control environmental pollution and harm caused by waste gas, waste water, waste residue, medical waste, dust, malodorous gas, radioactive substances, noise, vibration, light radiation and electromagnetic radiation generated in production, construction or other activities.
Enterprises and institutions that discharge pollutants shall establish a responsibility system for environmental protection, and clarify the responsibilities of the person in charge of the unit and relevant personnel.
Key pollutant discharge units shall install and use monitoring equipment in accordance with relevant state regulations and monitoring norms, ensure the normal operation of monitoring equipment, and keep original monitoring records.
It is strictly prohibited to illegally discharge pollutants through concealed pipes, seepage wells, seepage pits, perfusion or tampering with or forging monitoring data, or through the abnormal operation of pollution prevention facilities to avoid supervision.
