Étude de l'épuration d'effluents de composition complexe par électrocoagulation et des couplages intervenants entre le traitement électrochimique et l'étape de séparation : application à l'industrie textile et papetière

Abstract : Electrocoagulation eliminates simultaneously a large spectrum of organic pollutants, dyes and heavy metals; therefore, it has been studied extensively. However, little work has been undertaken to investigate more thoroughly its behaviors. The complexity of the effluent for which it is particularly interesting to use this method also makes it difficult to analyze the results. This thesis aims to contribute to understanding the coupling electrocoagulation - settling and interactions associated with complex effluent multi-pollutants. Also a continuous reactor has been addressed in the case of a simple synthetic sewage to better understand the differences from the batch operation. This study is based on a systematic approach based on the elementary processes of electrocoagulation: Electrochemistry, coagulation and physical separation. Each process provides a basis for studying the interactions that then the overall modeling process. To study the electro-decantation couplings, industrial textile effluents were treated by electrocoagulation followed by a settling step, without flocculent. The effect of parameters on electrocoagulation settleability of treated effluent and removal efficiency of pollution has been studied in particular by following the settling velocity in the test tube and calculating the SVI. The second objective of this our work was to study the coupling between the different types of pollution and to eliminate a particular paper mill effluent containing organic pollutants and arsenic. Finally, we conducted a study on the performance of EC-coupling settling for the treatment of a synthetic textile effluent flow reactor. The latter is composed of two elements, the electrochemical cell followed by a settling chamber
