Abstract

L'invention concerne des systèmes et des procédés de traitement de gaz brûlé et des eaux usées générés par le traitement du gaz brûlé et consistant à injecter le gaz brûlé, un fluide de traitement de gaz brûlé éliminant le dioxyde de soufre du gaz brûlé et un agent de conditionnement d'acide organique dans un laveur de gaz/absorbeur par oxydation humide; injecter les eaux usées laveur de gaz FGD générées par le laveur de gaz/absorbeur par oxydation humide dans un réacteur biologique anoxique pour sensiblement dénitrifier les eaux usées de laveur de gaz FGD; et injecter les eaux usées de laveur de gaz FGD sensiblement dénitrifiées résultantes dans un réacteur biologique anaérobie pour sensiblement réduire la quantité de sulfate et/ou de métaux lourds sélectionnés dans les eaux usées de laveur de gaz FGD.
