Prevention and control of environmental pollution and chemical pollution caused by production and living activities, including prevention and control of "three wastes" pollution, dust, radioactive substances and noise produced by industrial production, harmful gases produced by transportation activities, pollutants discharged by ships at sea, toxic and harmful chemicals used in industrial and agricultural production and people's life, and smoke, sewage and garbage discharged from urban life.
2, reduce 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.
Step 3 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.
Step 4 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.
5. Actively protect nature.
Protect the natural environment with special value, including providing effective protection for rare species and their living environment, special natural development relics, geological phenomena, landforms and landscapes.
In addition, urban and rural planning, controlling soil erosion and desertification, planting trees, controlling population growth and distribution, and rationally allocating productive forces also belong to environmental protection.
