Roginska, Joanna Maria. « Microbial electrochemical snorkel for nitrate reduction in constructed wetlands ». Electronic Thesis or Diss., Université de Lorraine, 2021. http://www.theses.fr/2021LORR0314.
Texte intégralThe exceeded nitrate concentration in water is caused by the use of nitrogen fertilizers in agriculture and may result in negative environmental consequences. One of the solutions are constructed wetlands – wastewater treating engineered systems. However, this approach might not be fast enough, especially in periods when nitrate concentration is high and in not sufficiently big wetlands. This thesis is exploring strategies for accelerating nitrate reduction. The denitrification requires an electron donor, such as organic carbon. These compounds appear more in the sediment, while nitrate is present in water, hence we hypothesized that increasing the sediment/water interface will facilitate the access to electron donors and accelerate denitrification, and we evaluated this in the first part of this work. Other strategy to increase this interface was to implement a bioelectrochemical system (BES) with nitrate-reducing biocathode. The BES we studied is a Microbial Electrochemical Snorkel (MES), which consists of one piece of electrode immersed in two different media, here in sediment and water. On the part in sediment an anodic biofilm is developed, which is oxidizing the organic matter. The electrons are then transported to the part of electrode in water, where the cathodic biofilm grows and the reduction of oxygen or nitrate process occurs.This work aims to create the conditions for developing MES with nitrate-reducing biocathodic part and to characterize its electrochemical properties, microbial community and nitrate reduction efficiency. A literature review about the nitrate-reduction biocathodes is provided in Chapter 1. Chapter 2 describes the materials and methods used in this work. Chapter 3 explores the effect of increasing the water/sediment interface on nitrate reduction. To increase this interface, sediment was arranged vertically in the tubes made of water-permeable tissue. This experiment was first performed in stationary state and by increasing the interface area 10 times, the nitrate reduction was increased up to 6.5 times. The volume of the sediment, its origin and composition, did not have a significant influence on nitrate reduction. This experiment was later repeated in flow, which resulted in 3.5 times faster nitrate reduction, stable for 53 days. The scenario of applying this method in the constructed wetland is considered.Chapter 4 covers the preliminary studies of MES: the choice of electrode materials and the ratio between part in water and sediment. The development of MES is confirmed by electrochemical analysis and study of microbial community. The addition of nitrate caused the increase of cathodic current and shift of potential. The laboratory results were compared with the results on the field.Next, MES of increased size and optimized distribution between sediment and water was built (Chapter 5), which confirmed the improvement in nitrate reduction. An increase of cathodic current was observed after addition of nitrate, and it decreased after nitrate was reduced. This current was linked to electron transfer reaction occurring at relatively high potentials when compared to the literature. Microbial analysis showed the significant differences between the community on biocathodes and in sediment and water.The final chapter is exploring potential role of electrodes in sediments for accelerating nitrate removal. It was implemented by integrating electrode in vertical sediment tubes that were studied in Chapter 3. Stainless steel and carbon felt electrodes were tested, and the latter caused indeed fast nitrate reduction. However, additional experiments showed that the mechanism is not nitrate reduction on the electrode. Carbon felt in sediment caused the release of species and the rapid nitrate reduction occurring in water. Changing the water eliminated the advantage in nitrate reduction. But, clear electrochemical reaction could still be observed at the electrode in sediment after nitrate addition
