Document Type and Number:
WIPO Patent Application WO/2023/210593
Kind Code:
A1
Abstract:
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.
