A new symbiotic microorganism strain for treating polyvinyl alcohol-containing waste water and a method for treating polyvinyl alcohol-containing wastewater using the same

摘要

The present invention relates to a new symbiotic microorganism strain for treating polyvinyl alcohol-containing wastewater, and a method for treating polyvinyl alcohol-containing wastewater using the same, wherein polyvinyl alcohol, which is a polymer synthesizing compound used in the dyeing industry and the like, Decomposition of vinyl alcohol decomposes microorganisms into dyeing wastewater. In summer, water temperature of about 40C, biodegradability of polyvinyl alcohol used as a crude detergent, and difference in decomposition rate depending on the degree of polymerization of polyvinyl alcohol There is a problem in that the efficiency of wastewater treatment is greatly reduced. To solve this problem, polyvinyl alcohol having a polymerization degree of from 500 to 30,000, which can utilize at least 80% A new symbiotic strain, Pasteurela sea It is the process of developing the genus Molytica and Pseudomonas sp. And supplying it to the wastewater processors to treat dyeing wastewater that contains more than 40C at room temperature and contains a large amount of PVA.
