【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%.

【Abstract】 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.
