計畫中文摘要	本計畫為二年期之計畫，今年主要工作項目為：(一)實驗室先導試驗；(二)八斗子漁船加油站場址現地模場試驗；(三)台中供油中心場址現場離地模場試驗及(四)生物炭生產系統建置及生物炭製備、特性分析。 在實驗室先導試驗的部分，完成生物炭搭配土壤通氣法、生物堆法及植生復育法對土壤TPH污染分解效率之試驗，其結果顯示，添加生物炭可提升生物通氣法對TPH之分解效率達27%；另在生物堆法及植生復育法，可能因土壤濃度較低，有足夠通氣，不同試驗組之間之分解效率並未有顯著差異，以至於沒有特別凸顯添加生物炭的功效。但在培地茅株高及生質量方面，添加生物炭試驗組之株高及生質產量都較未施用生物炭組高，施用樹枝生物炭2.5%及5%試驗組，培地茅地下部生質量提升1.4倍及2.2倍，地上部提高1.4倍及1.6倍；添加稻殼生物炭2.5%，地下部生質量提高1.5倍，地上部提高1.4倍；以兩種生物炭相比較，樹枝生物炭效果優於稻殼生物炭。而施用菌液亦可提升培地茅株高及生質量，推測主要原因應在於菌液提供營養成分，促進培地茅生長。綜合上述，實驗室先導試驗結果顯示，土壤添加生物炭可達到提升TPH分解速率及提升作物生長情形。對於土壤TPH污染土壤的整治可達到一定程度的促進作用。且生物炭的添加可以達到固碳作用，具有綠色永續，低碳固碳效益。 模場試驗的部分，進行了「八斗子漁船加油站場址」及增加完成「台中供油中心場址」兩個現地試驗。本年度主要係以八斗子場址為主，目前已完成試驗場址整地，因受到生物炭量產系統自日本輸入期程的延誤，系統建置有延遲情形，所幸9月底系統已完成建置，並進行測試運轉。目前已完成連續運轉測試，可進行連續投產，預估於10月底前可產出本年度計畫所需之生物炭，預計在11月初可完成現場模場試驗建置工作，後續持續進行場址管理及定期監測。台中供油中心模場試驗為本計畫額外增加之工作內容，為配合綠色永續整治案例影片的製作以供未來進行綠色永續整治(GSR)之參考，已完成一年的試驗，對於高濃度TPH污染土壤，培地茅的種植及生物炭的施用皆有助於土壤TPH的分解效率；在種植前期添加生物炭，對植體高度未有太大差異，但在種植後8個月開始，添加生物炭試驗組明顯高於未添加。 在生物炭製備及特性比較分析方面，目前已完成市售以慣用悶燒法製備之相思木炭、菱殼炭，及實驗室高溫爐以三種溫度，自製稻殼、梨樹樹枝及玉米桿生物炭，共十一種生物炭的特性分析。後續將針對高效率厭氧還原系統製備各種資材生物炭，分析其特性。比較各種資材、製備方法生物炭之碳穩定性，評估其施用於土壤對作物生長、污染整治之效益提升情形，並評估其固碳效益。
計畫英文摘要	This project is a two-year plan. The main work items this year are: (1) Laboratory pilot test; (2) On-site mock-up test at Badouzi Fishing Boat Gas Station site; (3) Taichung Fuel Supply Center site On-site off-ground mold field test and (4) biochar production system construction and biochar preparation and characteristic analysis. In the pilot test part of the laboratory, a test was completed on the decomposition efficiency of soil TPH pollution by biochar combined with soil aeration method, bio-pile method and replantation method. The results showed that adding biochar can improve the decomposition efficiency of TPH by bio-aeration method. Reaching 27%; in addition, in the biopile method and the replantation method, perhaps because the soil concentration is low and there is sufficient aeration, there is no significant difference in the decomposition efficiency between different test groups, so that the effect of adding biochar is not particularly highlighted. . However, in terms of plant height and biomass quality of Pedimus, the plant height and biomass yield of the biochar-added test group were higher than those of the non-biochar application group. In the test groups with 2.5% and 5% branch biochar, the underground biomass quality of Pedimus increased by 1.4 times and 2.2 times, the above-ground part increased by 1.4 times and 1.6 times; adding 2.5% of rice husk biochar, the quality of underground parts increased by 1.5 times, and the above-ground part increased by 1.4 times; comparing the two biochars, the effect of branch biochar was better than that of rice husk Biochar. The application of bacterial liquid can also increase the plant height and growth quality of Pedemora. It is speculated that the main reason should be that the bacterial liquid provides nutrients and promotes the growth of Pedemora. Based on the above, laboratory pilot test results show that adding biochar to soil can increase the decomposition rate of TPH and improve crop growth. It can promote the remediation of TPH-contaminated soil to a certain extent. The addition of biochar can achieve carbon sequestration, which is green, sustainable, and low-carbon. As for the mock-up field test, two on-site tests were completed at the "Badouzi Fishing Boat Gas Station Site" and the "Taichung Fuel Supply Center Site". This year, the main focus is on the Badouzi site, and the test site preparation has been completed. Due to delays in the import of the biochar mass production system from Japan, the system construction was delayed. Fortunately, the system construction was completed at the end of September. and conduct a test run. The continuous operation test has been completed and can be put into continuous production. It is expected that the biochar required for this year's plan will be produced by the end of October. It is expected that the on-site mold field test and construction work will be completed by the beginning of November. Site management will continue in the future. and regular monitoring. The Taichung Oil Supply Center mold field test is an additional work content of this project. In order to cooperate with the production of green sustainable remediation case videos for reference in future green sustainable remediation (GSR), the one-year test has been completed. For high-tech The concentration of TPH contaminates the soil. The planting of Pedigree and the application of biochar all contribute to the decomposition efficiency of soil TPH. Adding biochar in the early stage of planting does not have much difference in the height of the plant, but starting 8 months after planting, The test group with added biochar was significantly higher than those without addition. In terms of biochar preparation and comparative analysis of characteristics, we have currently completed the commercially available acacia charcoal and water chestnut charcoal prepared by the conventional smoldering method, and the laboratory high-temperature furnace at three temperatures to make homemade rice husk, pear tree branches and corn stalk biomass. Charcoal, characteristic analysis of a total of eleven biochars. In the follow-up, various biochar materials will be prepared for high-efficiency anaerobic reduction systems and their characteristics will be analyzed. Compare the carbon stability of biochar from various materials and preparation methods, evaluate the effect of its application on soil on crop growth and pollution control, and evaluate its carbon sequestration efficiency.
