摘　　要：通过实验室模拟试验及现场观测研究了泰达再生水景观河道底泥TP和PO4-P(磷酸盐以P计)沉积特性,分析了再生水中的TP和PO4-P沉积到河道底泥的原因,得出了水溶液的TP和PO4-P随时间变化的沉积规律.结果显示,以再生水作为水源时,水体中TP和PO4-P是沉积的;同时在实验室模拟试验研究中,TP和PO4-P沉积量达到最大值时所需时间为1d,TP和PO4-P的最大沉积量分别为95.15%和96.56%;实际观测研究中TP和PO4-P沉积量达到最大值所需时间比室内试验所需时间长,约为7.5d,TP和PO4-P的最大沉积量小于实验室试验的沉积量,分别为85.10%和87.43%.The deposition effects of the total phosphorous （TP） and phosphate （PO4-P）in TEDA Reuse Water ＆ Landscape River are studied, and the sedimentation reason of TP, PO4-P are analyzed, then the settling curve of TP and PO4-P is drawn in recycled water which is changed with time. When the reuse water is used as the water source, TP and PO4-P deposit bottom silt. In laboratory simulation test, the needed time of the max deposition ratio for TP and PO4-P is 1 day, meanwhile, the max deposition ratio of TP and PO4-P are 95.15%, 96.56% respectively. According to practical observation, the needed time of the deposition ratio is 7.5 days, longer for TP and PO4-P to reach max deposition level than in the laboratory test, and the deposition ratio of the TP and PO4-P is 85.10% and 87.43% respectively, lower than in the laboratory test.
