Abstract[English]
This invention is to provide a method for stably, inexpensively and highly efficiently treating amide compounds containing organic wastewater.
It is enabled that treat the organic wastewater containing amide compounds by activated-sludge treatment in one or more aeration tanks. The amide compounds include amide ether solvents such as 3-methoxy-N,N-dimethyl propanamide and 3-methoxy-N,N-dimethyl propenamide; N,N-disubstituted acrylamides such as N,N-dimethylacrylamide, N,N-diethyl acrylamide and N-[3-(dimethylamino)propyl]acrylamide; N-monosubstituted acrylamides such as N-isopropyl acrylamide, N-octyl acrylamide, N-(2-hydroxyethyl)acrylamide, N-ethylhexyl acrylamide, N-oleyl acrylamide and N-stearyl acrylamide; acryloyl morpholine and diacetone acrylamide.[French]
L'invention concerne un procédé permettant de traiter de manière stable, peu coûteuse et très efficace des eaux usées organiques contenant des composés amides. Il est possible de traiter les eaux usées organiques contenant des composés amides par traitement de boues activées dans un ou plusieurs réservoirs d'aération. Les composés amides comprennent : les solvants éthers amides tels que le 3-méthoxy-N,N-diméthyl propanamide et le 3-méthoxy-N,N-diméthyl propénamide ; les acrylamides N,N-disubstitués tels que le N,N-diméthylacrylamide, le N,N-diéthyl acrylamide et le N-[3-(diméthylamino)propyl]acrylamide ; acrylamides N-monosubstitués tels que l'acrylamide N-isopropyle, l'acrylamide N-octyle, l'acrylamide N-(2-hydroxyéthyle), l'acrylamide N-éthylhexyle, l'acrylamide N-oléyle et l'acrylamide N-stéaryle ; la morpholine acryloyle et l'acrylamide diacétonique.
