Environmental protection projects mainly refer to water pollution prevention and control projects, air pollution prevention and control projects, solid waste treatment and disposal projects, physical contamination prevention and control projects and pollution restoration projects.
1, air pollution prevention and control project
Air pollution prevention and control engineering is a technical field in environmental protection engineering. Its function is to take engineering measures to prevent and control air pollution caused by human production and consumption activities, thus improving air quality. The common methods to prevent and control air pollution are condensation recovery method, absorption method, combustion method and adsorption method.
2, water pollution prevention and control project
Water pollution prevention and control engineering is also the first technical field in environmental protection engineering, which is closely related to local natural conditions. It is an environmental protection engineering technical measure to prevent, reduce or even eliminate water pollution, improve and maintain the quality of water environment, and rationally utilize water resources. First of all, it systematically detects water pollution and provides data for studying water pollution and environmental capacity. According to the function of water body, various environmental standards are stipulated to protect the quality of water environment, so as to determine the reasonable treatment degree of sewage. Water pollution prevention and control projects include the establishment of urban sewage treatment, industrial sewage treatment and rural sewage treatment.
3, solid waste prevention and control project
Solid waste treatment refers to the process of reducing the volume of solid waste and muddy substances discarded by human beings in production activities and life through physical means or chemical and biological effects, and accelerating their natural purification. However, in the process of treatment, secondary pollution should be avoided to ensure that toxic and harmful substances will not cause harm to human beings. Its contents include: solid waste compaction technology, crushing technology, curing treatment technology, incineration and pyrolysis technology, biological treatment technology.
4. Noise control project
Noise control engineering is to control the output of noise sources, control the emission and reception of noise, and ensure the acoustic environment required by people. Noise control projects cover a wide range, including air-conditioning rooms, garages, hotels, hospitals, shopping malls, office buildings and other environments.
