Effect of River Bank Material on Organic Pollution Degradation Capacity

Fund Project:

摘要: 研究了干砌石、浆砌石、蜂巢格宾和生态砖等河岸材料对河流有机污染物降解能力的影响。4种材料中,以生态砖为河岸的河流中总有机碳(TOC)沿程降解率分别是蜂巢格宾和浆砌石的6.14和3.15倍(p<0.05);生态砖、干砌石和蜂巢格宾河段中溶解性有机碳(DOC)沿程降解率分别是浆砌石的10.68、6.60和6.08倍(p<0.05)。生态砖和蜂巢格宾构筑的河岸的河流中,悬浮和附着微生物脂磷含量显著高于干砌石和浆砌石(p<0.05),最多可达到7.27nmolP/cm²和58.16nmolP/cm²,悬浮微生物脱氢酶(S-DHA)、荧光素双醋酸酯(FDA)、附着微生物硝酸还原酶活性(F-NRA)、碱性磷酸酶活性(APA)也显著高于干砌石和浆砌石(p<0.05)。河岸材料影响了微生物生物量及硝化等关键生化反应过程的酶活性,从而影响了河流中有机污染物的降解。

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.

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.
