Liang Zhang.

During his study, Liang Zhang investigated the fate of organic micro-pollutants in constructed wetlands (CWs). CWs are an eco-friendly and cost-effective technology to treat wastewater. In the recent years, they have gained attention for their capacity to remove organic micro-pollutants.

Liang Zhang’s research has focused on the role of the support matrix for the removal of model pharmaceuticals and pesticides. He has studied the effect of enhancing removal of the micro-pollutants by promoting co-metabolisation. Moreover, he has investigated the effects of wetland design and plant species on the removal rates, removal mechanisms and microbial community functions.

The findings obtained during his research contribute to a better understanding of how CWs can be better designed to improve micro-pollutants removal.

The PhD degree was completed at the Department of Bioscience, Aarhus University.
