【摘要】 通过49d的室内模拟实验,研究了3种不同构造的复合型生态浮床对富营养化水体的净化效果。结果表明,整个实验周期内,A浮床(香菇草+火山岩浮球填料)、B浮床(狐尾藻+海绵浮球填料)和C浮床(黄花水龙+组合填料)总磷最大去除负荷分别达到13.33、17.29和18.17mg/(d.m~2),氨氮最大去除负荷分别达到64.92、75.53和84.38 mg/(d.m~2),COD最大去除负荷分别达到619.45、614.06和1050.18 mg/(d.m~2)。研究发现,复合型生态浮床的污染净化能力受到浮床构造和底物浓度的影响。

【Abstract】 In this work,three integrated ecological floating bed systems,the AFB(planted with Hydrocotyle vulgaris and suspending volcanic rock as biofilm carrier),BFB(planted with Myriophyllum verticillatum L and suspending sponge as biofilm carrier)and CFB(planted with Jussiaea stipulacea Ohwi and suspended with combined biofilm carrier),were constructed to study their purifying effeciecies for treatment of eutrophic freshwater.The AFB,BFB and CFB was fould to have a biggest removal efficience of 13.33、17.29 and 18.17 mg/(d.m~2)for TP purification,64.92、75.53 and 84.38 mg/(d.m~2)for ammonium nitrogen purification,and 619.45、614.06 and 1050.18 mg/(d.m~2)for COD.The results indicated that the purifying capacities of the integrated ecological floating bed systems are affected by the system construction and the substrate concentraction as well.
