湿地是一种有效的废水处理技术，与传统的活性污泥系统相比具有几个优点。微生物群落在处理过程中至关重要，因为微生物能够通过生物降解实现实质性的净化。本工作的目标是监测原生动物的丰度和多样性的基质中的6个实验室规模的自由水面人工湿地和调查其适用性作为指示生物在这些系统中的处理效率。磷和总大肠菌群的去除率之间的相关性，观察到在原生动物类群的存在下，而去除有机负荷和无机氮的增加原生动物的多样性在土壤/水界面的情况下。结果表明，原生动物可以作为人工湿地处理效果的生物指示剂，此外，它们的存在与出水水质有关。
Wetlands represent an efficient wastewater treatment technique, with several benefits over the conventional activated sludge system. Microfaunal community is of outmost importance in treatment processes as the microorganisms are able to achieve substantial decontamination through biodegradation. The objectives of this work were the monitoring of protozoan's abundance and diversity in the matrix of six bench scale Free Water Surface constructed wetlands and the investigation of their applicability as indicator organisms for treatment efficiency in these systems. A correlation between the phosphorous and Total Coliforms removal rates was observed in the presence of increased protozoan taxa, while removal of organic loading and inorganic nitrogen was increased in the case of increased protozoan diversity in the soil/water interface. Results revealed that protozoa may be used as bioindicators of treatment efficiency in constructed wetlands; in addition their presence was related to the effluent quality.
