There are many aspects of environmental protection. It can be analyzed from the following aspects.
1.Air pollution, environmental governance, environmental protection.
The main pollutants include dust, nitrogen oxides, sulfides, dioxins, organic gases and a series of toxic and harmful gases.
Such as sulfur dioxide, nitric oxide, nitrogen dioxide, etc. Heavy metals can be carried in the dust.
The main treatment methods, dust removal, desulfurization, denitrification. <>
2.Water pollution and environmental protection.
Inorganic pollutants include nitrogen, phosphorus, non-metals (e.g., arsenic, cyanide, etc.), metals, and heavy metals (e.g., mercury, cadmium, chromium). Nitrogen and phosphorus are the main substances that lead to eutrophication of closed water bodies. Many heavy metals have a direct toxic effect on the human body and aquatic life.
Organic pollutants include biodegradable and non-biodegradable pollutants. Among them, the degradation process of biodegradable pollutants consumes dissolved oxygen in the water, causes hypoxia in the water body and the death of aquatic organisms, destroys the function of the water body, and the organic matter is degraded by microorganisms under anaerobic conditions to produce harmful or odorous substances such as hydrogen sulfide, ammonia, and low-grade fatty acids. Refractory biodegradable pollutants such as pesticides, halogenated hydrocarbons, aromatic compounds, etc., are generally highly toxic, chemically and biologically stable, and easy to accumulate in organisms.
The main treatment method is through sedimentation tank, with water treatment equipment circulation and integration.
3.Soil pollution control and environmental protection.
The main pollutants include air and water pollutants, as well as some other chemical contaminants and nuclear pollution.
The main remediation method is up to standard after a long period of soil remediation projects.
Environmental protection is related to people's life, health and safety, and a good environment enables people to have a comfortable job, live with peace of mind and be conducive to physical health. The polluted environment makes people worried, the smelly chemical pollution of the air, the acid rain and alkaline rain, the toxic polluted water is discharged indiscriminately, and the excessive use of pesticides and fertilizers is rotten, all kinds of things have seriously affected people's normal life and caused hundreds of millions of people to demand environmental protection. <>
