carbon adsorption + reverse osmosis + disinfection” is under research and demonstration to determine if the water’s quality could meet drinking water requirements. In
addition, ozone technology has been widely used in recycled water plants in Beijing
and Tianjin.
At present, the recycled water is mainly used for various purposes, including
for municipal use, industry, agriculture, and eco-environment. For the purposes and
