    摘要:

    通过微宇宙试验,以添加碳源、翻耕、覆膜为调控因子,研究生物强化措施对多氯联苯污染土壤的修复效果,并对修复前后土壤微生物数量以及功能多样性进行研究。结果表明,土壤翻耕处理是最有效的修复措施,修复效率达到29.3%;添加淀粉与覆膜处理,效果相近,并且均显著高于对照。添加淀粉和翻耕均显著增加了土壤中细菌、真菌和放线菌的数量,但降低了土壤微生物功能多样性。而覆膜处理则使土壤微生物数量及其活性和多样性均下降。可见,不同的调控措施不仅能够强化土壤中多氯联苯的降解,同时也会影响到土著微生物群落结构及其活性和功能。

    Abstract:

    A microcosmic experiment was set to investigate effects of controlling measures like adding carbon sources,plowing and mulching,on bioremediation of polychlorinated biphenyls (PCBs) polluted soils and changes in soil microbial ecology. Results showed that soil stirring was the most effective method,being 29.3% in depletion rate,and adding starch and mulching with plastic film came the next,similar in effect to each other,PCBs degradation was significantly enhanced in all these treatments. Compared to the control,the treatments of addition of starch and cultivation of soil showed much higher density of soil microbiology,but lower-utilization ability of communities for carbon(AWCD) and lower functional diversity. In the treatment of mulching,the density of soil microbiology,the utilization ability of communities for carbon and the functional diversity all decreased. The results indicate that the controlling measures could not only influence the depletion rate of PCBs,but also alter the structure and affect activity and function of the soil microorganism.
