英文摘要: Five kinds of oxidoreductases in the substrate of integrated vertical flow constructed wetland (IVCW) were determined, and the results indicated that there were significant differences in different seasons for oxidoreductases; the enzyme activities of peroxidase were significantly higher in spring, summer and autumn than those in winter (P < 0.05); and the enzyme activities of polyphenol oxidase and catalase were highest in autumn; the enzyme activity of dehydrogenase was significantly higher in summer and winter than in spring and autumn (P < 0.05) the enzyme activities of nitrate reductase was significantly higher in spring and winter than in summer and autumn (P < 0.01) The spatial characteristics and activities of polyphenol oxidase, catalase and dehydrogenase in down-flow chamber were significantly higher than those in up-flow one, except peroxidase, while the activities were depressive with the deepening of substrate layer. But there was no obvious difference in nitrate reductase activities in the different depths of the substrate of the IVCW. Fig 6, Tab 3, Ref 17.
