技術說明

本研究展示了利用新型生物強化土壤發酵反應槽在適當條件控制下能夠促進高氯戴奧辛快速生物降解而去毒化。我們建立新型生物強化反應器系統在間歇曝氣及添加適量營養鹽等條件下，控制在鹼性環境且添加戴奧辛降解菌劑的反應槽對於戴奧辛的總毒性當量及高氯(7-8氯)戴奧辛同源物在2個月內分別有72 %及88-99 %的去除率，高於中性與酸性條件。在反應槽中發現第56天有66%的OCDF轉換成1,2,3,7,8,9-HxCDF，說明此生物程序的設計與條件控制可使八氯戴奧辛發生還原脫氯反應。菌劑添加強化了土壤菌群的多樣性與數量，有助於土壤戴奧辛的共代謝分解。這些研究成果可推廣應用於實場中。 The study demonstrates the use of a novel bioaugmented bioreactor to detoxify the polychlorinated dioxin-polluted soil under the designed conditions. The bioaugmented reactor that was operated at pH 8.5 could have higher removal efficiency of total toxicity equivalency (72%) and individual congeners (88%-99%) than the performance at pH conditions of 7.5 and 6.5. In the Reactor, we observed that 66% of OCDF has been dechlorinated into 1,2,3,7,8,9-HxCDF at day 56, suggesting that the designed reactor configuration and operation model can enhance the dechlorination of fully-chlorinated dioxins. The bioaugmentation with the bacterial agents developed in this study can enhance the microbial diversity and quantity in soil, which aids the co-metabolism of soil dioxins. The parameters and relevant knowledge obtained from this study can be valuable for future applications.
