What does medium water mean?
Reclaimed water, also known as reclaimed water and reused water, refers to water that can be used beneficially after wastewater or rainwater has been properly treated to meet certain water quality indicators and meet certain usage requirements.
The name "reclaimed water" comes from Japan. There are many interpretations of the definition of "reclaimed water". It is called "reclaimed water" in sewage engineering and "recycled water" in factories. Water quality is generally used as a mark of distinction. . It mainly refers to non-potable water that can be reused within a certain range after urban sewage or domestic sewage has been treated to meet certain water quality standards.
Reclaimed water refers to water that after appropriate treatment of wastewater or rainwater reaches certain water quality indicators, meets certain usage requirements, and can be used beneficially. Compared with seawater desalination and cross-basin water transfer, recycled water has obvious advantages. From an economic point of view, the cost of recycled water is the lowest. From an environmental point of view, sewage recycling can help improve the ecological environment and achieve a virtuous cycle of water ecology.
Advantages of reclaimed water
Non-potable water that can be used within a certain range can be used in many aspects of urban landscape and people’s lives. In order to solve the problem of water shortage, urban sewage recycling has become increasingly important. Urban sewage recycling has advantages compared with the development of other water sources. As a regeneration water source, sewage can basically occur simultaneously with the generation of sewage. That is to say, as long as urban sewage is generated, there will be a reliable source of recycled water.
At the same time, the sewage treatment plant is the source of recycled water, which is relatively close to urban recycled water users and provides convenient water supply. The scale of wastewater recycling is flexible. Large-scale recycled water plants can be built at the edge of the city, or small recycled water plants or integrated treatment equipment can be built in various residential areas and public buildings. The scale can be large or small, depending on local conditions.
