Reclaimed water reuse
Reclaimed water refers to wastewater or rainwater after appropriate treatment, to attain certain water quality indicators, and can meet certain use requirements, which can be beneficially use. Reclaimed water is the second source of water for cities.Urban wastewater recycling is one of the effective ways to improve the comprehensive utilization of water resources and reduce water pollution.Reasonable reuse of reclaimed water can not only reduce the water environment pollution, but also to alleviate the contradiction of water scarcity. And this is an important measure to achieve sustainable development. The recycling and resource utilization of wastewater has considerable social, environmental and economic benefits, and has become a necessary choice for solving water problems in the world.
