The major problems and countermeasures for reclaimed water used for urban landscape waterbody

Nowadays, as the water resource is becoming scarce, application of reclaimed water to urban landscape water body has positive water-saving significance. This paper briefly introduced some domestic and international project cases of reclaimed water reuse. The potential risks of utilizing reclaimed water to landscape water body such as water quality, eutrophication, and safety were also analyzed. Combining with project cases, some water quality protection measures were proposed, and some suggestions such as water purified biology, environmental remediation on the projects of implementing reclaimed water to landscape water body were put forward as well. And some countermeasures such as perfect water quality standards,degrading the functions of water bodies,rational using water treatment measures,etc.were put forward in the end.
