| Abstract: | From printing and dyeing actived sludge, PVA- degrading symbiotic bacteria was isolated. The symbiotic bacteria is composed of B1 and B2. During PVA biodegradation, B1 produces a certain growth factor for B2, B2 produces PVA-degrading enzyme. The PVA-degrading characters of the symbiotic bacteria are examined. When the concentration of PVA was 0.1, 0.5, 1g/L respectively,more than 80% of PVA was degradated after 7days. During the treatment of the dyeing and printing wastewater, when the temperature was 30 degree C ,the removal of COD(Cr) was 69.75%, the proper treating time was 12h. |
