1. What is water recycling
What is intermediate water: in terms of sewage engineering, it is called "reclaimed water"; in terms of factories, it is called "reclaimed water", and water quality is generally taken as the distinguishing mark.
It mainly refers to the non-drinking water which can be reused within a certain range after the treatment of urban or domestic sewage reaches a certain water quality standard.
The water after the deep purification treatment of urban sewage treatment facilities (including the water after the secondary treatment of sewage treatment plants and the water after the further treatment and large buildings, the bath water of the living community, dish water and other concentrated water after the treatment) is collectively referred to as "intermediate water".
The water quality is between the tap water (upper water) and the sewage (water) discharged into the pipeline, so it is also called "middle water".
Middle water utilization is also called sewage reuse.
Water recycling, on the one hand, opens up a second water source for urban water supply, which can greatly reduce the consumption of "sheung shui" (tap water).
On the other hand, it solves the pollution problem of "sewage" to water resources to a certain extent, playing an economic and environmental role.
