A vertical-flow wetland system was tested for treatment of liquid sludge with high organic concentrations using an organic substrate (peat/crushed pine bark, 1/1) as growing medium. Mesocosms (1 m(3)) were planted with either Phragmites australis Cav., Typha latifolia L., or Iris pseudacorus L. The aim of the work was to determine the feasibility of using an organic substrate in treatment wetlands, through the study of its temporal patterns and of its impact on the water output quality. Results confirmed that the organic substrate can be used in such wetlands treating highly organic sludge, without clogging phenomena for the experimental period. The organic substrate released soluble organic matter but few mineral elements. Over the experimental period, substrate TOC concentration did not change while N concentration increased. Plants showed positive impact on substrate temporal patterns and also on the outflow water quality. Overall, Phragmites seemed to be more beneficial than Typha and Iris.
使用有机基质(泥炭/碎松树皮,1/1)作为生长介质,对垂直流湿地系统处理高有机浓度液体污泥进行了测试。中型试验池(1立方米)种植了芦苇、宽叶香蒲或黄菖蒲。该工作的目的是通过研究其时间模式及其对出水水质的影响,确定在处理湿地中使用有机基质的可行性。结果证实,有机基质可用于此类处理高有机污泥的湿地,在实验期间不会出现堵塞现象。有机基质释放出可溶性有机物,但很少释放矿物元素。在实验期间,基质的总有机碳(TOC)浓度没有变化,而氮浓度增加。植物对基质的时间模式以及出水水质都有积极影响。总体而言,芦苇似乎比香蒲和黄菖蒲更有益。
