ACTIVATED SLUDGE EXAMINATION METHOD, METHOD OF DETERMINING OPTIMAL OPERATION CONDITIONS FOR ACTIVATED SLUDGE TREATMENT APPARATUS, METHOD OF IDENTIFYING MICROORGANISMS WITH ACTIVATED SLUDGE ABNORMAL FACTORS AND METHOD OF IMPROVING OPERATION OF ACTIVATED SLUDGE TREATMENT APPARATUS
ACTIVATED SLUDGE EXAMINATION METHOD, METHOD OF DETERMINING OPTIMAL OPERATION CONDITIONS FOR ACTIVATED SLUDGE TREATMENT APPARATUS, METHOD OF IDENTIFYING MICROORGANISMS WITH ACTIVATED SLUDGE ABNORMAL FACTORS AND METHOD OF IMPROVING OPERATION OF ACTIVATED SLUDGE TREATMENT APPARATUS
PROBLEM TO BE SOLVED: To provide a method of examining activated sludge and identifying microorganisms with activated sludge abnormal factors, as well as a method of optimizing the operation of an active sludge treatment apparatus and a method of improving operations, with a simple method without the need for detailed gene analysis of DNA and/or RNA and without specifying the name of the microorganism species.;SOLUTION: An activated sludge examination method is a method of examining activated sludge with an activated sludge treatment apparatus that determines abnormalities in the waste water treatment capacity of microorganisms of the activated sludge by comparing the quantitative ratio (rRNA/rDNA) of rRNA and rDNA thereof, or determines abnormalities in the waste water from changes in the number of rRNA bands of measured microorganism bands of rRNA of microorganisms of the activated sludge separated by nucleic acid electrophoresis. Furthermore, by examining the microorganisms of the activated sludge tested by varying the operation conditions of the activated sludge by a test device using the examination method, it is possible to determine the optimal operation conditions for the activated sludge treatment apparatus.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
