Effect of River Bank Material on Organic Pollution Degradation Capacity |
| |
| Abstract: | Microbial biomass and enzyme activities for dry masonry, cellular gabion, eco-block and masonry were investigated to reveal the effects of different river bank materials on organic pollution degradation capacity. Total organic carbon (TOC) degradation ratio of eco-block bank were 6.14 and 3.15 times significantly higher than that of cellular gabion and masonry, respectively (p<0.05). Dissolved organic carbon (DOC) degradation ratio of eco-block bank, dry masonry and cellular gabion were 10.6, 6.60 and 6.08 times significantly higher than that of masonry, respectively (p<0.05). Lipid phosphorus contents of suspended microbe and microbial film in river with eco-block and cellular gabion were up to 7.27 nmol P/cm2 and 58.16 nmol P/cm2 ,respectively. Dihydroartemisinin of suspended dehydrogenase activity (S-DHA), fluorescein diacetate activity(FDA), nitrate reductase activity of microbial film (F-NRA), alkaline phosphatase activity (APA) of eco-block were also significantly higher than that of dry masonry and masonry (p<0.05). River bank materials affect organic degradation capacity by microbial biomass and enzyme activities. |
