Environmental engineering technology is an engineering field involving the protection and improvement of environmental quality. The main goal of environmental engineering technology is to reduce environmental pollution, protect natural resources and improve the quality of human life. The following are some main aspects and tasks usually involved in environmental engineering technology:

Water resources management: Environmental engineering technology helps to manage and protect water resources, including water supply, wastewater treatment, water quality monitoring and water resources sustainability. This includes designing and maintaining water treatment facilities to ensure the safety and sanitation of drinking water, and treating industrial and municipal wastewater to reduce water pollution.

Air pollution control: This field mainly studies how to reduce air pollution, including monitoring and controlling air pollutants, designing and managing air quality improvement projects, and taking measures to reduce greenhouse gas emissions.

Solid waste management: Environmental engineering technology helps to design, plan and manage the solid waste treatment and disposal system, so as to reduce the amount of waste, improve the recovery rate and reduce the dependence on landfills.

Soil protection and restoration: the focus of this field is to protect soil quality, including the cleaning and restoration of contaminated soil, and to prevent soil erosion and degradation.

Sustainable energy: Environmental engineering technology is also related to the production and use of sustainable energy, including the development and utilization of solar energy, wind energy and biomass energy to reduce dependence on fossil fuels.

Environmental monitoring and data analysis: Environmental engineering technology also involves monitoring environmental quality, collecting and analyzing data to assess the seriousness of environmental problems and formulate solutions.

Abide by environmental laws and regulations: Environmental engineering technology helps enterprises and government agencies to abide by environmental laws and standards to ensure that their activities have the least impact on the environment.

In a word, environmental engineering technology is a multi-field engineering field, aiming at improving and protecting our natural environment and creating a healthier and more sustainable living environment. It requires engineers to have interdisciplinary knowledge and skills to solve complex environmental problems.
