Title (EN) METHOD FOR TREATMENT OF AMMONIA-CONTAINING WASTEWATER
(FR) PROCÉDÉ DE TRAITEMENT DES EAUX USÉES AMMONIAQUÉES
(JA) 含アンモニア廃水の処理方法
Abstract:
(EN) The invention aims at providing a method for wastewater treatment by which at least the ammonia nitrogen content and chemical oxygen demand (COD) of wastewater can be lowered to levels satisfying the effluent standards under Sewage Water Law. A method for wastewater treatment, characterized by subjecting a wastewater (except liquid wastes from photograph developing) which has COD of 0.3g/L or above and an ammonia nitrogen content of 0.5g/L or above to physicochemical or biological treatment and then treating the resulting wastewater with a treatment comprising ammonia oxidizing bacteria and an inorganic dispersion medium on which the bacteria are inclusively immobilized.
(FR) L'invention vise à fournir un procédé de traitement des eaux usées selon lequel au moins la teneur en azote ammoniacal et la demande chimique en oxygène (DCO) des eaux usées peuvent être abaissées à des niveaux satisfaisant les normes de l’effluent selon la loi des eaux d’égouts (Sewage Water Law). La présente invention concerne un procédé de traitement des eaux usées caractérisé par le fait de soumettre une eau usée (à l’exception des déchets liquides provenant d’un développement photographique) qui a une DCO supérieure ou égale à 0,3 g/L et une teneur en azote ammoniacal supérieure ou égale à 0,5 g/L à un traitement physico-chimique ou biologique et ensuite de traiter l'eau usée résultante au moyen d’un traitement comprenant des bactéries oxydant l'ammoniaque et un support de dispersion inorganique sur lequel les bactéries sont inclusivement immobilisées.
(JA)  廃水中の少なくともアンモニア性窒素量及びCODを下水道法に基づく排水基準を満たすレベルに低減できる廃水処理方法を提示すること。  化学的酸素要求量(COD)が0.3g/L以上でかつアンモニア性窒素量が0.5g/L以上である、写真処理廃水以外の廃水を、物理化学的に又は生物学的に処理したのちアンモニア酸化細菌と無機物分散体とを含有する包括固定体により処理することを特徴とする廃水処理方法。
