Résumé
Constructed Wetlands (CWs) are nature-based solutions that can effectively provide treated wastewater for irrigation with variable nutrient contents to meet the specific needs of different crops, thus promoting sustainable agricultural practices. However, emerging organic pollutants are often not eliminated completely. The intensification of wastewater treatment plants through continuous or intermittent active aeration has been successfully implemented, but at the cost of higher investment and operating costs. In this context, bioaugmentation of CWs appears to be a promising strategy for improving treatment efficiency by taking advantage of the interactions between plants and microorganisms, and the central role of the latter in contaminant degradation processes and their transfer in agroecosystems. Here, we present the results of our studies using commercially available products containing spores of symbiotic fungi Trichoderma asperellum for enhancing the biodegradation of micropollutants in a pilot-scale partially saturated vertical flow constructed wetland.
