摘要

采用多孔混凝土为生态护岸载体，联合微生物、绿色植物等生态因子构建特定岸坡生态系统来研究水源地水质改善效果。实验结果表明，在停留时间(RT)为6 d时，系统对CODMn、UV254、NH+4-N、NO2--N、TN的平均去除率分别达到20.9％、13.4％、81.4％、96.8％和67.7％，相比硬质化岸坡的空白渠，CODMn、UV254、NH+4-N、NO2--N、TN的平均去除率仅为9.6％、5.0％、70.8％、42.4％和34.6％。通过该系统中多孔混凝土载体、水生植物和基质上富集的微生物等生态因子协同作用，使得有机物、氮类污染物去除效果明显。

Abstract

An experimental model was made on the improvement of sources water quality through the construction of a special riverine ecosystem using ecological embankments

which consisted of porous concrete

microorganism and hydrophytes. It was found that

with six day as retention time (RT)

the removal rates were 20.9% for CODMn

13.4% for UV254

81.4% for NH+4-N

96.8% for NO2-N and 67.7% for TN. In contrast

in the control pool with hard embankment

the removal rates only reached 9.6% for CODMn

5.0% for UV254

70.8% for NH+4-N

42.4% for NO2-N and 34.6% for TN. Through coordination of all constituent elements of special aquatic ecosystem such as porous concrete

hydrophytes and substrate microorganisms

organic pollutants and nitrogen can be removed effectively.
