1
As a research for treatment of waste water from acetaldehyde plant by biological method, we investigated general characteristics of the waste water, and isolated and identified some useful bacteria which effectively treated its waste water. Among the total number of 53 strains which were grown in waste water from an acetaldehyde plant, the strains AW-6, AW-22, AW-38 and AW-41 were found to be useful for COD removal of waste water. COD. and BODs of the waste water were 5260 ppm and 6452 ppm, respectively, and pH was 1.85. And the main organic component in waste water was acetic acid which was contained 6.76%. By the taxonomical characteristics, the strains AW-6, AW-22, AW-38 and AW-41 were identified as Micrococcus roseus, Micrococcus !oleos, Microbacterium lacticum and Microbacterium laevaniformans or similar strain, respectively.
