| 中文摘要: |
| 选取稻草作为碳源物质，探究纤维素分解菌、溶解氧、温度3个因素对稻草释碳效果的影响。研究发现：在30℃缺氧条件下，加入纤维素分解菌的稻草最大释碳量可达8.4 mg/d，而且试验5 d后稻草的释碳量可维持在4 mg/d 以上；未加纤维素分解菌的稻草最大释碳量仅4.1 mg/d。在30℃尧引入纤维素分解菌的条件下，溶解氧浓度高的稻草释碳效果低于溶解氧浓度低的稻草。不同温度下稻草释碳量关系为30℃>20℃>10℃。 |
| 英文摘要: |
| The effect of cellulose decomposition bacteria, DO and temperature on carbon release was explored with straw used as
carbon source. The results showed that the carbon release of straw could be maintained 4 mg/d above after the fifth day of the trial, and the maximal value was up to 8.4 mg/d with cellulose decomposing bacteria under the condition of 30℃ and lack of oxygen, while it was only 4.1 mg/d without cellulose decomposing bacteria under the same conditions. The higher DO was, the less amount of carbon release would be at the temperature of 30℃ with cellulose decomposing bacteria. The relationship between the temperature and the amount of carbon release showed as followed: 30℃>20℃>10℃. |
