污水处理外文文献
Wastewater treatment is a critical process that involves the
removal of pollutants and contaminants from water, making it
safe for discharge back into the environment or for reuse. This
process is important because it ensures that water resources are
not polluted or depleted, which can have severe consequences on
the environment and public health. In this document, we will
explore some important foreign language literature on
wastewater treatment, its different types, and the various
techniques used in the process.
Types of Wastewater Treatment
Generally, wastewater treatment can be classified into two
categories: primary treatment and secondary treatment. Primary
treatment involves the physical removal of large, suspended
solids from wastewater. This process primarily relies on
sedimentation and filtration techniques. Secondary treatment, on
the other hand, is a biological process that involves the use of
microorganisms to break down organic matter in wastewater. It
usually follows primary treatment and is more effective at
removing pollutants than primary treatment.
Techniques Used in Wastewater Treatment There are several techniques used in the treatment of
wastewater. Some of these techniques include:
1. Biological Treatment: This is the most commonly used
method in secondary treatment, and it involves the use of
biological agents such as bacteria and microorganisms to degrade
organic matter in wastewater. The process involves aerobic or
anaerobic degradation of pollutants in wastewater. During this
process, microorganisms convert organic matter into carbon
dioxide and water.
2. Chemical Treatment: This method involves adding
chemicals, such as coagulants and flocculants, to wastewater to
remove suspended solids and other contaminants. Chemical
treatment is commonly used in primary treatment processes.
3. Physical Treatment: This method involves the removal of
solids and other particles from wastewater using physical
processes such as sedimentation, filtration, and screening.
Physical treatment is usually used at the beginning of the
treatment process.
4. Membrane Technology: This is a newer process in
wastewater treatment that uses filters with tiny pores to separate
contaminants from wastewater. It is mainly used in tertiary
treatment, which is the final stage of treatment before discharge.
Foreign Language Literature on Wastewater Treatment There are several foreign language literature sources on
wastewater treatment. Some of the most important ones include:
1. The Water Environment Federation: This is a non-profit
organization that provides publications and research on
wastewater treatment. They offer peer-reviewed journals and
books that provide valuable information on the latest research
and technology in wastewater treatment.
2. Water Research Journal: This is an international journal
that publishes research on water treatment and related fields. It
offers peer-reviewed articles on topics such as wastewater
engineering, water quality, and water resources.
3. Environmental Science and Technology Journal: This is a
publication that covers various aspects of environmental science
and technology, including water treatment. It provides
peer-reviewed articles on research in environmental science and
technology.
Conclusion
Wastewater treatment is an essential process that ensures
that water resources are not polluted or depleted. It involves
different treatment methods, such as physical, chemical, and
biological treatment. Among the different sources of literature on
wastewater treatment, the Water Environment Federation, the
Water Research Journal, and the Environmental Science and
Technology Journal are valuable sources of information. New advances in technology mean that wastewater treatment is
becoming more efficient and effective, ensuring the safe
discharge of treated wastewater back into the environment or for
reuse.
