摘要
通过正交试验研究了白腐真菌在煤炭降解转化过程中煤样粒度、菌液用量、降解作用时间等各因素对其降解率的影响.还对白腐真菌对煤降解转化产物进行了元素分析,在此基础上探讨了白腐菌对煤生物降解转化的规律.实验结果表明,白腐真菌对经硝酸预处理后的义马褐煤样有较强的降解作用,15 d的时间能把粒度-0.2 mm的经硝酸预处理的义马褐煤降解41.54%,降解作用主要是白腐真菌在培养过程中释放出来的酶作用的结果.
The influence of coal granularity, quantity of white rot fungus liquid, and time of degradation on biodegradation percentage was studied by orthogonal test. The production of coal degradation by white rot fungus was also studied. Based on these studies, the degradation law of coal biodegradation was also worked out. The results show that white rot fungus has a great role in coal biodegradation of lignite sample that was pretreated by nitric acid. It can degrade lignite with granularity 0. 2 minus, which was pretreated by nitric acid, by 41.54% within 15 days. The biodegradation is mainly attributed to the enzyme released from the fungus in the process of cultivating.
