Graduates can work in government environmental planning departments, environmental resources consulting companies, or as environmental professionals or engineers in some companies in the fields of chemistry, manufacturing, engineering, mining and petroleum.
So far, people still have different understandings of the subject of environmental engineering. Some people think that environmental engineering is a subject to study the principles and methods of environmental pollution prevention and control technology, mainly to study the prevention and control technology of waste gas, waste water, solid waste, noise, radioactive substances, heat and electromagnetic waves that cause pollution; Some people think that environmental engineering should include environmental system engineering, environmental impact assessment, environmental engineering economy and environmental monitoring technology besides pollution prevention technology.

Although there are different views on the research contents of environmental engineering, according to the present situation of environmental engineering development, its basic contents mainly include air pollution prevention and control engineering, water pollution prevention and control engineering, solid waste treatment and utilization, comprehensive prevention and control of environmental pollution, environmental system engineering and so on.
Environmental Engineering Everyone exchanges gases with the atmosphere through breathing. The amount of gas exchange between an adult and the atmosphere in one day is about 10 ~ 12 cubic meters. Usually, a person can live for five weeks without food and water. But if you don't breathe for five minutes, you will die. Therefore, air, especially clean air, is indispensable for human life all the time.
However, since the mid-20th century, the types and quantities of pollutants entering the atmosphere have been increasing. There are about 100 kinds of pollutants that have polluted the atmosphere and substances that may pollute the atmosphere, which has aroused people's attention. Among them, there are sulfur oxides, nitrogen oxides, fluoride, hydrocarbons, carbon oxides and other harmful gases, as well as particles and aerosols floating in the atmosphere containing a variety of harmful substances.
Some pollutants in the atmosphere come from the physical movements and changes of nature itself, and some come from human production and consumption activities. The main task of air pollution prevention and control project is to control harmful gases emitted by human production activities, and to study the principle and method of removing particulate matter from industrial waste gas.
Water is indispensable for the survival and development of all living things. The substances contained in water are very complex, and almost all the elements in the periodic table can be found in water. Wastewater discharged from human production and consumption activities, especially industrial wastewater and urban sewage, enters the water body and causes water pollution.
Therefore, it is the main task of water pollution prevention and control project to adopt the methods of wastewater physical treatment, wastewater chemical treatment, wastewater biological treatment and wastewater physical and chemical treatment, make full use of environmental self-purification ability, prevent, reduce and even eliminate water pollution, improve and maintain the quality of water environment, formulate wastewater discharge standards, rationally utilize water resources and strengthen water resources management.
