摘  要：
通过空白对照和种植美人蕉2组处理系统,研究了美人蕉对泰达景观河道含盐再生水的净化效果以及水力停留时间(H RT)对水体净化效果的影响。结果表明,H RT对水体中污染物COD、TN、NH3-N、NO3-N、TP、PO4-P的净化效果有明显的影响,各主要污染物去除率随H RT的变化范围为COD的去除率19.64%~45.09%,TN的去除率为17.52%~63.05%,NH3-N的去除率为23.24%~82.47%,NO3-N的去除率为15.67%~62.43%,TP的去除率为24.20%~61.59%,PO4-P的去除率为20.69%~62.26%。水体中TDS含量在4500~6786 m g/L范围内对美人蕉及其水处理系统的净化效果没有影响;美人蕉系统的pH值均比空白对照组的低。由于美人蕉根系和微生物的吸收与分解作用,在水体中种植美人蕉能明显改善水质净化效果,对水体pH值控制也有一定作用。

摘  要：
Canna indica Linn was planted in salty water and without it which were made of 2 systems of purifying water.The effects of Canna indica Linn and hydraulic retention time in the purifying efficiencies for salty water treatment in TEDA Landscape River were studied in this paper.The results showed that the salty water purifying efficiencies for COD,TN,NH_3-N,NO_3-N,TP and PO_4-P were significant different with hydraulic retention time,moreover,removal rate of COD is from 19.64% to 45.09%,TN is from 17.52% to 63.05%,NH_3-N is from 23.24% to 82.47%,NO_3-N is from 15.67% to 62.43%,TP is from 24.20% to 61.59%,PO_4-P is from 20.69% to 62.26%;TDS is from 4500 mg/L to 6786 mg/L in the water which is no effected on purifying efficiencies for water quality and Canna indica Linn's vegetation;pH of Canna indica Linn's system for water treatment is smaller than empty control's.Under the combination function of the absorbability and decomposition of Canna indica Linn roots and microbiology,the water quality of treatment system planted with Canna indica Linn was obvious improved while the water pH was controlled.
