The high grade gray water was pretreated by biologic contact oxidation on load of 0.72 KgBOD5·m-3·d-1
and then posttreated by constructed wetland. On the basis of experiment
it was found that: Totle nitrogen (TN) was the restrictive index of the combinational technique. To meet the reclaimed water quality standard and reuse for waterscape
the peak hydraulic load of constructed wetland was 0.50 m·d-1 in summer (30~36 ℃)
and 0.33 m·d-1 in winter (8~12 ℃). And the load ratio of the peak hydraulic under the summer and winter conditions was 3:2. With the experimental results and reclaimed water quantity requirements in different seasons of buildings
