    • Phosphorus, nitrogen and BOD are removed from organic waste liquid containing the same by mixing the organic waste liquid with activated sludge which is substantially free of oxygen, nitric acid and nitrous acid and subjecting the mixture to the action of the activated sludge under anaerobic conditions which forms a mixture of a liquid rich in soluble phosphorus and an activated sludge low in phosphorus. The sludge and liquid are separated. A portion of the liquid is subjected to solid-liquid separation to form a liquid high in phosphorus and a sludge low in phosphorus. This latter sludge is, along with the other portion of the liquid and the sludge from which the liquid has been initially separated are mixed with oxygen, in the presence of nitric acid or nitrous acid and subjected to aerobic biological oxidation. This results in the formation of a liquid low in phosphorus and an activated sludge. The activated sludge is used as the activated sludge free of oxygen, nitric acid and nitrous acid in the first stage of the process. The liquid high in phosphorus from the portion subjected to solid-liquid separation of the separated liquid is subjected to chemical removal of the soluble phosphorus therein.
    • 通过将有机废液与基本上不含氧,硝酸和亚硝酸的活性污泥混合,并将该混合物在厌氧条件下进行活性污泥的作用,从含有其的有机废液中除去磷,氮和BOD, 形成富含可溶性磷的液体和磷含量低的活性污泥的混合物。 污泥和液体分离。 将一部分液体进行固液分离以形成高磷的液体和低磷的污泥。 在硝酸或亚硝酸的存在下,后一种污泥与液体的最初分离液体和其中最初分离液体的污泥一起与氧气混合并进行有氧生物氧化。 这导致磷和活性污泥中液体低的形成。 在该过程的第一阶段,活性污泥用作无氧,硝酸和亚硝酸的活性污泥。 来自分离液体的固液分离部分的高磷的液体经受化学除去其中的可溶性磷。

    • The present invention relates to a method of treatment of waste water which is characterized by removal of both organic substances and phosphorus from phosphorus-containing organic waste water by novel microorganisms that are fortified in phosphorus-incorporating and/or accumulating abilities. The method for treatment of waste water according to the present invention allows to efficiently remove both organic substances and phosphorus from organic waste water by genetically-engineered microorganisms that have acquired improved abilities in phosphorus incorporation and/or accumulation by genetic transformation using one or more vector plasmids carrying, together with a self-replicative DNA fragment, one of the DNA fragment combinations which include at least one member of the group of (a) a DNA fragment containing a gene involved in phosphate transport through cell membranes; (b) a DNA fragment containing a polyphosphate kinase structure gene; and (c) a DNA fragment containing a structure gene of an enzyme involved in intracellular ATP supply, excluding the sole use of the DNA fragment containing a polyphosphate kinase structure gene.
