Novel Nitrogen Removal Process Using Attached Activated Sludge

Autor: Kenji Furukawa, Sakai Yukihiro, Motonobu Nakaoka, Wataru Takatsuji

Publikováno v: Japanese Journal of Water Treatment Biology. 38:211-218

In a conventional activated sludge aeration tank, organic nitrogen was almost completely converted to ammonium but very little was converted to oxidized forms of nitrogen (nitrite and nitrate) . Nitrification and denitrification in the aerated unit p

Publikováno v: Sen'i Gakkaishi. 53:125-130

To establish a textile dye wastewater treatment methods, the ozonation and the successive biodegradation of carboxymethyl cellulose (CMC) which was widely used as thickener for textile printing process were investigated. The degradation of CMC by the

Mineralization and desulfonation of 3-nitrobenzenesulfonic acid by Alcaligenes sp. GA-1

Autor: Motonobu Nakaoka, Masahiro Takeo, Yoshimichi Maeda, Ken Takatani, Takeya Nagayama

Publikováno v: Journal of Fermentation and Bioengineering. 83:505-509

A 3-nitrobenzenesulfonic acid (3-NBS)-degrading bacterium was isolated from a batch enrichment culture containing 3-NBS and yeast extract, and identified as an Alcaligenes sp. In a batch degradation test, the isolate, named GA-1, utilized 3-NBS as a

Publikováno v: Sen'i Gakkaishi. 53:507-511

Three kinds of azo dyes underwent rapid biodegradation under anaerobic condition. Aromatic amines were produced as the degradation products of azo dyes determined by HPLC analyses. The products were further degraded and 60% of the COD components coul
