摘要：以北京汉石桥潜流湿地为研究对象,分析了2014-2015年水体中总溶解固体(Turb)与浊度(TDS)的去除率,研究潜流湿地对水中总溶解固体与浊度的去除效果。结果表明:①潜流湿地对浊度(TDS)和总溶解固体(Turb)在全年均具有一定的处理效果,1-12月去除率表现为先增加后降低的趋势,平均去除率分别为85.6%和6.4%;②温度成为制约潜流湿地污染物去除的重要因素,其中总溶解固体和浊度与温度的相关系数分别为0.669和0.489;③对总溶解性固体和浊度的比较发现,在估值背景浓度下,面积速率常数均高于零背景值时的面积速率常数,当污染负荷较低时,潜流湿地对总溶解性固体和浊度去除的面积速率常数随进水污染负荷的升高而增加。
Employing the subsurface constructed wetlands in Hanshiqiao Nature Reserve as the study area, this study analyzed the TDS and Turbidity removal rate of the effluent water from 2014 to 2015. The results indicated that:(1)The overall removal rate was positive, which confirmed the TDS and Turb removal effect of the subsurface constructed wetlands in the whole year. The removal rate of each index showed an increasing trend at the beginning then a decreasing trend, and the average removal efficiencies of TDS and Turb in the subsurface constructed wetlands were 85.6% and 6.4%.(2) temperature acted as important restricting factors during the wetland TDS and Turb removal, with a coefficient of 0.669 and 0.489 respectively. However, the temperature had more influence on the removal rate of Turb.(3)Comparison of the TDS and Turb implied that the area rate constants calculated from the estimated background concentration were higher than those calculated from zero background concentration. The area rate constant of DS and Turb increased exponentially with the increasing of influent mass loading when the mass loading was lower.
